<p>Npolys: /* Candidate Capabilities */</p> <hr /> <div>==Genesis and Strategic Overview==<br /> <br /> Web3D Consortium working groups currently define specification goals and requirements. Working group efforts are often the focus for defining and testing new X3D components.<br /> <br /> We publicly review these goals annually during [http://web3dconference.org/ Web3D Conference] and [http://www.siggraph.org/attend/annual-conferences SIGGRAPH] Birds of a Feather (BOF) meetings ([http://www.web3d.org/event/siggraph-2016-conference-colocated-web3d-2016-anaheim-california SIGGRAPH 2016], upcoming SIGGRAPH 2017).<br /> <br /> Suggestions, development and discussion via the [http://web3d.org/mailman/listinfo/x3d-public_web3d.org x3d-public mailing list] is ongoing.<br /> <br /> X3D version 3.4 Development efforts were evolutionary improvements to the widely proven X3D Graphics architecture. Consortium members decided to skip version 3.4 and go straight to version 4.0, prior goals and requirements have all been merged here.<br /> <br /> The [http://www.web3d.org/wiki/index.php?title=X3D_version_4.0_Development#Candidate_Capabilities Candidate Capabilities] list shows that a lot of interesting capabilities have been proposed and are under way for X3D version 4. However, topics on this list are not guaranteed to be completed! Rather these are all works in progress.<br /> <br /> Activity and approval proceeds based on technical contributions and Web3D Consortium Member priorities. Please consider [http://web3d.org/membership/join joining Web3D Consortium] to help advance 3D graphics on the Web.These X3D version 4.0 Development efforts are considering potentially major additions to the baseline X3D architecture.<br /> <br /> * Major technology under consideration: [http://www.web3d.org/wiki/index.php/X3D_and_HTML5 HTML5], [http://www.w3.org/community/declarative3d/ Declarative 3D], CSS, [http://www.x3dom.org X3DOM] (see [http://web3d.org/wiki/images/f/f2/X3DOM_4_WebGL_audience_10_2013.pdf Summary slides (Oct 2013)]), and [http://titania.create3000.de/cobweb/ Cobweb]<br /> * Major technology under consideration: [http://www.web3d.org/wiki/index.php/X3D_and_Augmented_Reality Mixed and Augmented Reality (MAR)] (renamed from Augmented Reality Continuum (ARC)<br /> * Relaxing prior design constraints can enable a broader new basis for X3D integration<br /> * Normalizing interaction semantics with HTML5 can further open up X3D for the vast majority of Web authors<br /> <br /> Please [http://www.web3d.org/realtime-3d/contact contact us] if you think additional technologies need to be considered. X3D Futures planning is primarily a Web3D Consortium member-only activity, with community input.<br /> <br /> == Legacy Issues ==<br /> <br /> We plan to confirm the existence of complete capabilities for X3D v3.3 prior to final approval of X3D version 4.<br /> <br /> * Full support for all existing X3D v3.3 components:<br /> ** At least two compatible implementations (including at least one in open source) plus repeatable example scenes<br /> ** Layer, ParticleSystems, RigidBodyPhysics, Shaders, TODO others<br /> ** TransformSensor node: [http://doc.instantreality.org/documentation/nodetype/TransformSensor/ IGD] and [http://www.parallelgraphics.com/developer/products/cortona/extensions/transformsensor/ old Cortona]<br /> ** Note that it is not a requirement that all features and capabilities in X3D V3.3 are included in V4.0<br /> <br /> * Is it necessary for Layout component to be deprecated or improved?<br /> * Are there other features or capabilities that should not or are not able to move into V4.0?<br /> <br /> == Candidate Capabilities ==<br /> <br /> Each of the following possibilities for X3D version 4 have been discussed by the various X3D working groups during meetings and on mailing lists.<br /> Each potential capability is considered to be a feasible (and in most cases, straightforward) addition to the existing X3D version 3.3 architecture.<br /> <br /> *'''Appearance'''<br /> **'''Images''': recommended formats for imagery and video (.gif .bmp .flv .exr .hdr etc.) - details below:<br /> ***'''GIF''': [http://www.w3.org/Graphics/GIF/spec-gif89a.txt &quot;Graphics Interchange Format, Version 89a&quot;], W3C. 31 July 1990.<br /> ***'''BMP''': [https://en.wikipedia.org/wiki/BMP_file_format BMP].

X3D V3.x presumes a controlled environment that interacts with the rest of the (computing) world through a well defined API (called SAI).

Are they still needed, perhaps for multiscreen or CAVE support?<br /> * Mashup and interoperability support: is anything else needed for broader use with the Web?

<p>Npolys: /* Papers, Tutorials and Presentations */</p> <hr /> <div>=== The Medical Working Group ===<br /> The International Standards Organization (ISO) standard for 3D graphics over the Internet is Extensible 3D (X3D), which is maintained and developed by the Web3D Consortium. The initiative of the Web3D Consortium’s <br /> Medical Working Group (MWG) is to specify and implement MedX3D – an extension to the open and royalty-free X3D standard to support advanced medical visualization functionality and medical data exchange (for more information see [[#MedX3D: X3D and Volume Rendering|MedX3D: X3D and Volume Rendering]]). '''The MWG has specified and demonstrated cross-platform volume rendering styles (i.e., transfer functions), segmentation and ontology support, and data import/export capabilities for interactive presentation'''.<br /> <br /> The Medical Working Group is an interdisciplinary effort. The different backgrounds of the members range from medical subject matter experts, over computer scientists from academia to engineers and experts from industry. Thus potential users and future providers are involved as well as experts to work on technical solutions. In November 2012, the Web3D Consortium Medical Working Group released its [http://web3d.org/wiki/images/a/a2/Portable_and_Interoperable_Views_II.pdf 2012 Opportunities Whitepaper: Portable and Interoperable Views of Medical Image Data with ISO Extensible 3D (X3D)], outlining the path forward for cross-platform, reproducible volume rendering and the health care enterprise.<br /> <br /> ==X3D and Volume Rendering==<br /> The reproduction of volume-rendered presentations of medical image data across platforms and the healthcare enterprise presents several challenges, especially due to data and view incompatibilities and lock-in to proprietary systems. But, explicit 3D visual presentations of medical images can provide significant advantages because this type of rendering is more truly representational of the object being imaged (the human body)- it is a more intuitive and easily-read format. It is increasingly common to render a three dimensional (3D) model from a CT, MRI, PET and X-Ray scan to better interpret the size, orientation and other spatial relationships of the patient’s anatomy as necessary for diagnosis, intervention (surgery) and therapy. <br /> <br /> Until recently, there was little hope of interoperability for interactive 3D and 4D presentations to break out of the hospital PACS and to be archived and shared across the enterprise. With the continual advancement in computing and graphical power over the last decade, specialized workstations and software capacity has become available to display this type of 3D imaging on a common laptop. It is an imminent future when the handheld tablets on the market are capable of sustained hardware-accelerated graphics performance. <br /> <br /> Our original work (Web3D.org) for '''TATRC ([http://www.web3d.org/documents/medical/2008/Web3D_TATRC_FinalReportPublic.pdf W81XWH-06-1-0096])''' developed and demonstrated the integration of expressive volume rendering with X3D over the web with several client platforms. This set of functionalities was validated by industry experts and formalized into a specification with two separate, multi-platform implementations. The new component includes an expressive range of volume rendering styles as well as means to assign separate styles to different segments, and to create isosurfaces within the volume. In 2012, this specification has ultimately become an official part of [http://www.web3d.org/realtime-3d/specification/active ISO X3D 3.3]. <br /> <br /> Much of the required functionality is specified in the X3D 3.3 draft International Standard, including the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/texture3D.html Texturing3D Component (Clause 33)] and the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/volume.html Volume Rendering Component (Clause 41)] to support several compose-able styles for Volume Rendering for Medical Imaging, geology and other non-invasive sensing modalities.

<p>Npolys: /* Papers, Tutorials and Presentations */</p> <hr /> <div>=== The Medical Working Group ===<br /> The International Standards Organization (ISO) standard for 3D graphics over the Internet is Extensible 3D (X3D), which is maintained and developed by the Web3D Consortium. The initiative of the Web3D Consortium’s <br /> Medical Working Group (MWG) is to specify and implement MedX3D – an extension to the open and royalty-free X3D standard to support advanced medical visualization functionality and medical data exchange (for more information see [[#MedX3D: X3D and Volume Rendering|MedX3D: X3D and Volume Rendering]]). '''The MWG has specified and demonstrated cross-platform volume rendering styles (i.e., transfer functions), segmentation and ontology support, and data import/export capabilities for interactive presentation'''.<br /> <br /> The Medical Working Group is an interdisciplinary effort. The different backgrounds of the members range from medical subject matter experts, over computer scientists from academia to engineers and experts from industry. Thus potential users and future providers are involved as well as experts to work on technical solutions. In November 2012, the Web3D Consortium Medical Working Group released its [http://web3d.org/wiki/images/a/a2/Portable_and_Interoperable_Views_II.pdf 2012 Opportunities Whitepaper: Portable and Interoperable Views of Medical Image Data with ISO Extensible 3D (X3D)], outlining the path forward for cross-platform, reproducible volume rendering and the health care enterprise.<br /> <br /> ==X3D and Volume Rendering==<br /> The reproduction of volume-rendered presentations of medical image data across platforms and the healthcare enterprise presents several challenges, especially due to data and view incompatibilities and lock-in to proprietary systems. But, explicit 3D visual presentations of medical images can provide significant advantages because this type of rendering is more truly representational of the object being imaged (the human body)- it is a more intuitive and easily-read format. It is increasingly common to render a three dimensional (3D) model from a CT, MRI, PET and X-Ray scan to better interpret the size, orientation and other spatial relationships of the patient’s anatomy as necessary for diagnosis, intervention (surgery) and therapy. <br /> <br /> Until recently, there was little hope of interoperability for interactive 3D and 4D presentations to break out of the hospital PACS and to be archived and shared across the enterprise. With the continual advancement in computing and graphical power over the last decade, specialized workstations and software capacity has become available to display this type of 3D imaging on a common laptop. It is an imminent future when the handheld tablets on the market are capable of sustained hardware-accelerated graphics performance. <br /> <br /> Our original work (Web3D.org) for '''TATRC ([http://www.web3d.org/documents/medical/2008/Web3D_TATRC_FinalReportPublic.pdf W81XWH-06-1-0096])''' developed and demonstrated the integration of expressive volume rendering with X3D over the web with several client platforms. This set of functionalities was validated by industry experts and formalized into a specification with two separate, multi-platform implementations. The new component includes an expressive range of volume rendering styles as well as means to assign separate styles to different segments, and to create isosurfaces within the volume. In 2012, this specification has ultimately become an official part of [http://www.web3d.org/realtime-3d/specification/active ISO X3D 3.3]. <br /> <br /> Much of the required functionality is specified in the X3D 3.3 draft International Standard, including the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/texture3D.html Texturing3D Component (Clause 33)] and the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/volume.html Volume Rendering Component (Clause 41)] to support several compose-able styles for Volume Rendering for Medical Imaging, geology and other non-invasive sensing modalities.

<p>Npolys: /* Papers, Tutorials and Presentations */</p> <hr /> <div>=== The Medical Working Group ===<br /> The International Standards Organization (ISO) standard for 3D graphics over the Internet is Extensible 3D (X3D), which is maintained and developed by the Web3D Consortium. The initiative of the Web3D Consortium’s <br /> Medical Working Group (MWG) is to specify and implement MedX3D – an extension to the open and royalty-free X3D standard to support advanced medical visualization functionality and medical data exchange (for more information see [[#MedX3D: X3D and Volume Rendering|MedX3D: X3D and Volume Rendering]]). '''The MWG has specified and demonstrated cross-platform volume rendering styles (i.e., transfer functions), segmentation and ontology support, and data import/export capabilities for interactive presentation'''.<br /> <br /> The Medical Working Group is an interdisciplinary effort. The different backgrounds of the members range from medical subject matter experts, over computer scientists from academia to engineers and experts from industry. Thus potential users and future providers are involved as well as experts to work on technical solutions. In November 2012, the Web3D Consortium Medical Working Group released its [http://web3d.org/wiki/images/a/a2/Portable_and_Interoperable_Views_II.pdf 2012 Opportunities Whitepaper: Portable and Interoperable Views of Medical Image Data with ISO Extensible 3D (X3D)], outlining the path forward for cross-platform, reproducible volume rendering and the health care enterprise.<br /> <br /> ==X3D and Volume Rendering==<br /> The reproduction of volume-rendered presentations of medical image data across platforms and the healthcare enterprise presents several challenges, especially due to data and view incompatibilities and lock-in to proprietary systems. But, explicit 3D visual presentations of medical images can provide significant advantages because this type of rendering is more truly representational of the object being imaged (the human body)- it is a more intuitive and easily-read format. It is increasingly common to render a three dimensional (3D) model from a CT, MRI, PET and X-Ray scan to better interpret the size, orientation and other spatial relationships of the patient’s anatomy as necessary for diagnosis, intervention (surgery) and therapy. <br /> <br /> Until recently, there was little hope of interoperability for interactive 3D and 4D presentations to break out of the hospital PACS and to be archived and shared across the enterprise. With the continual advancement in computing and graphical power over the last decade, specialized workstations and software capacity has become available to display this type of 3D imaging on a common laptop. It is an imminent future when the handheld tablets on the market are capable of sustained hardware-accelerated graphics performance. <br /> <br /> Our original work (Web3D.org) for '''TATRC ([http://www.web3d.org/documents/medical/2008/Web3D_TATRC_FinalReportPublic.pdf W81XWH-06-1-0096])''' developed and demonstrated the integration of expressive volume rendering with X3D over the web with several client platforms. This set of functionalities was validated by industry experts and formalized into a specification with two separate, multi-platform implementations. The new component includes an expressive range of volume rendering styles as well as means to assign separate styles to different segments, and to create isosurfaces within the volume. In 2012, this specification has ultimately become an official part of [http://www.web3d.org/realtime-3d/specification/active ISO X3D 3.3]. <br /> <br /> Much of the required functionality is specified in the X3D 3.3 draft International Standard, including the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/texture3D.html Texturing3D Component (Clause 33)] and the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/volume.html Volume Rendering Component (Clause 41)] to support several compose-able styles for Volume Rendering for Medical Imaging, geology and other non-invasive sensing modalities. A Medical Interchange Profile of X3D nodes is also defined in Annex L : http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/MedInterchange.html. '''The node set of the X3D 3.3.

<p>Npolys: </p> <hr /> <div>=== The Medical Working Group ===<br /> The International Standards Organization (ISO) standard for 3D graphics over the Internet is Extensible 3D (X3D), which is maintained and developed by the Web3D Consortium. The initiative of the Web3D Consortium’s <br /> Medical Working Group (MWG) is to specify and implement MedX3D – an extension to the open and royalty-free X3D standard to support advanced medical visualization functionality and medical data exchange (for more information see [[#MedX3D: X3D and Volume Rendering|MedX3D: X3D and Volume Rendering]]). '''The MWG has specified and demonstrated cross-platform volume rendering styles (i.e., transfer functions), segmentation and ontology support, and data import/export capabilities for interactive presentation'''.<br /> <br /> The Medical Working Group is an interdisciplinary effort. The different backgrounds of the members range from medical subject matter experts, over computer scientists from academia to engineers and experts from industry. Thus potential users and future providers are involved as well as experts to work on technical solutions. In November 2012, the Web3D Consortium Medical Working Group released its [http://web3d.org/wiki/images/a/a2/Portable_and_Interoperable_Views_II.pdf 2012 Opportunities Whitepaper: Portable and Interoperable Views of Medical Image Data with ISO Extensible 3D (X3D)], outlining the path forward for cross-platform, reproducible volume rendering and the health care enterprise.<br /> <br /> ==X3D and Volume Rendering==<br /> The reproduction of volume-rendered presentations of medical image data across platforms and the healthcare enterprise presents several challenges, especially due to data and view incompatibilities and lock-in to proprietary systems. But, explicit 3D visual presentations of medical images can provide significant advantages because this type of rendering is more truly representational of the object being imaged (the human body)- it is a more intuitive and easily-read format. It is increasingly common to render a three dimensional (3D) model from a CT, MRI, PET and X-Ray scan to better interpret the size, orientation and other spatial relationships of the patient’s anatomy as necessary for diagnosis, intervention (surgery) and therapy. <br /> <br /> Until recently, there was little hope of interoperability for interactive 3D and 4D presentations to break out of the hospital PACS and to be archived and shared across the enterprise. With the continual advancement in computing and graphical power over the last decade, specialized workstations and software capacity has become available to display this type of 3D imaging on a common laptop. It is an imminent future when the handheld tablets on the market are capable of sustained hardware-accelerated graphics performance. <br /> <br /> Our original work (Web3D.org) for '''TATRC ([http://www.web3d.org/documents/medical/2008/Web3D_TATRC_FinalReportPublic.pdf W81XWH-06-1-0096])''' developed and demonstrated the integration of expressive volume rendering with X3D over the web with several client platforms. This set of functionalities was validated by industry experts and formalized into a specification with two separate, multi-platform implementations. The new component includes an expressive range of volume rendering styles as well as means to assign separate styles to different segments, and to create isosurfaces within the volume. In 2012, this specification has ultimately become an official part of [http://www.web3d.org/realtime-3d/specification/active ISO X3D 3.3]. <br /> <br /> Much of the required functionality is specified in the X3D 3.3 draft International Standard, including the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/texture3D.html Texturing3D Component (Clause 33)] and the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/volume.html Volume Rendering Component (Clause 41)] to support several compose-able styles for Volume Rendering for Medical Imaging, geology and other non-invasive sensing modalities.

<p>Npolys: /* Papers, Tutorials and Presentations */</p> <hr /> <div>=== The Medical Working Group ===<br /> The International Standards Organization (ISO) standard for 3D graphics over the Internet is Extensible 3D (X3D), which is maintained and developed by the Web3D Consortium. The initiative of the Web3D Consortium’s <br /> Medical Working Group (MWG) is to specify and implement MedX3D – an extension to the open and royalty-free X3D standard to support advanced medical visualization functionality and medical data exchange (for more information see [[#MedX3D: X3D and Volume Rendering|MedX3D: X3D and Volume Rendering]]). '''The MWG has specified and demonstrated cross-platform volume rendering styles (i.e., transfer functions), segmentation and ontology support, and data import/export capabilities for interactive presentation'''.<br /> <br /> The Medical Working Group is an interdisciplinary effort. The different backgrounds of the members range from medical subject matter experts, over computer scientists from academia to engineers and experts from industry. Thus potential users and future providers are involved as well as experts to work on technical solutions. In November 2012, the Web3D Consortium Medical Working Group released its [http://web3d.org/wiki/images/a/a2/Portable_and_Interoperable_Views_II.pdf 2012 Opportunities Whitepaper: Portable and Interoperable Views of Medical Image Data with ISO Extensible 3D (X3D)], outlining the path forward for cross-platform, reproducible volume rendering and the health care enterprise.<br /> <br /> ==X3D and Volume Rendering==<br /> The reproduction of volume-rendered presentations of medical image data across platforms and the healthcare enterprise presents several challenges, especially due to data and view incompatibilities and lock-in to proprietary systems. But, explicit 3D visual presentations of medical images can provide significant advantages because this type of rendering is more truly representational of the object being imaged (the human body)- it is a more intuitive and easily-read format. It is increasingly common to render a three dimensional (3D) model from a CT, MRI, PET and X-Ray scan to better interpret the size, orientation and other spatial relationships of the patient’s anatomy as necessary for diagnosis, intervention (surgery) and therapy. <br /> <br /> Until recently, there was little hope of interoperability for interactive 3D and 4D presentations to break out of the hospital PACS and to be archived and shared across the enterprise. With the continual advancement in computing and graphical power over the last decade, specialized workstations and software capacity has become available to display this type of 3D imaging on a common laptop. It is an imminent future when the handheld tablets on the market are capable of sustained hardware-accelerated graphics performance. <br /> <br /> Our original work (Web3D.org) for '''TATRC ([http://www.web3d.org/documents/medical/2008/Web3D_TATRC_FinalReportPublic.pdf W81XWH-06-1-0096])''' developed and demonstrated the integration of expressive volume rendering with X3D over the web with several client platforms. This set of functionalities was validated by industry experts and formalized into a specification with two separate, multi-platform implementations. The new component includes an expressive range of volume rendering styles as well as means to assign separate styles to different segments, and to create isosurfaces within the volume. In 2012, this specification has ultimately become an official part of [http://www.web3d.org/realtime-3d/specification/active ISO X3D 3.3]. <br /> <br /> Much of the required functionality is specified in the X3D 3.3 draft International Standard, including the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/texture3D.html Texturing3D Component (Clause 33)] and the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/volume.html Volume Rendering Component (Clause 41)] to support several compose-able styles for Volume Rendering for Medical Imaging, geology and other non-invasive sensing modalities.

<p>Npolys: /* Papers, Tutorials and Presentations */</p> <hr /> <div>=== The Medical Working Group ===<br /> The International Standards Organization (ISO) standard for 3D graphics over the Internet is Extensible 3D (X3D), which is maintained and developed by the Web3D Consortium. The initiative of the Web3D Consortium’s <br /> Medical Working Group (MWG) is to specify and implement MedX3D – an extension to the open and royalty-free X3D standard to support advanced medical visualization functionality and medical data exchange (for more information see [[#MedX3D: X3D and Volume Rendering|MedX3D: X3D and Volume Rendering]]). '''The MWG has specified and demonstrated cross-platform volume rendering styles (i.e., transfer functions), segmentation and ontology support, and data import/export capabilities for interactive presentation'''.<br /> <br /> The Medical Working Group is an interdisciplinary effort. The different backgrounds of the members range from medical subject matter experts, over computer scientists from academia to engineers and experts from industry. Thus potential users and future providers are involved as well as experts to work on technical solutions. In November 2012, the Web3D Consortium Medical Working Group released its [http://web3d.org/wiki/images/a/a2/Portable_and_Interoperable_Views_II.pdf 2012 Opportunities Whitepaper: Portable and Interoperable Views of Medical Image Data with ISO Extensible 3D (X3D)], outlining the path forward for cross-platform, reproducible volume rendering and the health care enterprise.<br /> <br /> ==X3D and Volume Rendering==<br /> The reproduction of volume-rendered presentations of medical image data across platforms and the healthcare enterprise presents several challenges, especially due to data and view incompatibilities and lock-in to proprietary systems. But, explicit 3D visual presentations of medical images can provide significant advantages because this type of rendering is more truly representational of the object being imaged (the human body)- it is a more intuitive and easily-read format. It is increasingly common to render a three dimensional (3D) model from a CT, MRI, PET and X-Ray scan to better interpret the size, orientation and other spatial relationships of the patient’s anatomy as necessary for diagnosis, intervention (surgery) and therapy. <br /> <br /> Until recently, there was little hope of interoperability for interactive 3D and 4D presentations to break out of the hospital PACS and to be archived and shared across the enterprise. With the continual advancement in computing and graphical power over the last decade, specialized workstations and software capacity has become available to display this type of 3D imaging on a common laptop. It is an imminent future when the handheld tablets on the market are capable of sustained hardware-accelerated graphics performance. <br /> <br /> Our original work (Web3D.org) for '''TATRC ([http://www.web3d.org/documents/medical/2008/Web3D_TATRC_FinalReportPublic.pdf W81XWH-06-1-0096])''' developed and demonstrated the integration of expressive volume rendering with X3D over the web with several client platforms. This set of functionalities was validated by industry experts and formalized into a specification with two separate, multi-platform implementations. The new component includes an expressive range of volume rendering styles as well as means to assign separate styles to different segments, and to create isosurfaces within the volume. In 2012, this specification has ultimately become an official part of [http://www.web3d.org/realtime-3d/specification/active ISO X3D 3.3]. <br /> <br /> Much of the required functionality is specified in the X3D 3.3 draft International Standard, including the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/texture3D.html Texturing3D Component (Clause 33)] and the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/volume.html Volume Rendering Component (Clause 41)] to support several compose-able styles for Volume Rendering for Medical Imaging, geology and other non-invasive sensing modalities.

<p>Npolys: /* Papers, Tutorials and Presentations */</p> <hr /> <div>=== The Medical Working Group ===<br /> The International Standards Organization (ISO) standard for 3D graphics over the Internet is Extensible 3D (X3D), which is maintained and developed by the Web3D Consortium. The initiative of the Web3D Consortium’s <br /> Medical Working Group (MWG) is to specify and implement MedX3D – an extension to the open and royalty-free X3D standard to support advanced medical visualization functionality and medical data exchange (for more information see [[#MedX3D: X3D and Volume Rendering|MedX3D: X3D and Volume Rendering]]). '''The MWG has specified and demonstrated cross-platform volume rendering styles (i.e., transfer functions), segmentation and ontology support, and data import/export capabilities for interactive presentation'''.<br /> <br /> The Medical Working Group is an interdisciplinary effort. The different backgrounds of the members range from medical subject matter experts, over computer scientists from academia to engineers and experts from industry. Thus potential users and future providers are involved as well as experts to work on technical solutions. In November 2012, the Web3D Consortium Medical Working Group released its [http://web3d.org/wiki/images/a/a2/Portable_and_Interoperable_Views_II.pdf 2012 Opportunities Whitepaper: Portable and Interoperable Views of Medical Image Data with ISO Extensible 3D (X3D)], outlining the path forward for cross-platform, reproducible volume rendering and the health care enterprise.<br /> <br /> ==X3D and Volume Rendering==<br /> The reproduction of volume-rendered presentations of medical image data across platforms and the healthcare enterprise presents several challenges, especially due to data and view incompatibilities and lock-in to proprietary systems. But, explicit 3D visual presentations of medical images can provide significant advantages because this type of rendering is more truly representational of the object being imaged (the human body)- it is a more intuitive and easily-read format. It is increasingly common to render a three dimensional (3D) model from a CT, MRI, PET and X-Ray scan to better interpret the size, orientation and other spatial relationships of the patient’s anatomy as necessary for diagnosis, intervention (surgery) and therapy. <br /> <br /> Until recently, there was little hope of interoperability for interactive 3D and 4D presentations to break out of the hospital PACS and to be archived and shared across the enterprise. With the continual advancement in computing and graphical power over the last decade, specialized workstations and software capacity has become available to display this type of 3D imaging on a common laptop. It is an imminent future when the handheld tablets on the market are capable of sustained hardware-accelerated graphics performance. <br /> <br /> Our original work (Web3D.org) for '''TATRC ([http://www.web3d.org/documents/medical/2008/Web3D_TATRC_FinalReportPublic.pdf W81XWH-06-1-0096])''' developed and demonstrated the integration of expressive volume rendering with X3D over the web with several client platforms. This set of functionalities was validated by industry experts and formalized into a specification with two separate, multi-platform implementations. The new component includes an expressive range of volume rendering styles as well as means to assign separate styles to different segments, and to create isosurfaces within the volume. In 2012, this specification has ultimately become an official part of [http://www.web3d.org/realtime-3d/specification/active ISO X3D 3.3]. <br /> <br /> Much of the required functionality is specified in the X3D 3.3 draft International Standard, including the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/texture3D.html Texturing3D Component (Clause 33)] and the [http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/components/volume.html Volume Rendering Component (Clause 41)] to support several compose-able styles for Volume Rendering for Medical Imaging, geology and other non-invasive sensing modalities.

<p>Npolys: /* Merge modified Xj3D codebases */</p> <hr /> <div>[[File:Xj3Dlogo-275.png|right]] Xj3D is an open-source Java implementation for X3D graphics. Xj3D is used to demonstrate many capabilities for specification development and supports a variety of valuable projects.<br /> <br /> == Discussion and consensus building ==<br /> <br /> We are using [mailto:source@web3d.org?subject=Xj3D%20Evolution source@web3d.org] mailing list <br /> to work out these possibilities and build stakeholder consensus.<br /> ([http://web3d.org/mailman/listinfo/source_web3d.org subscribe], [http://web3d.org/mailman/private/source_web3d.org/ archive])<br /> <br /> Consensus summary points<br /> * Basic strategy: we are evolving by re-versioning, not re-naming Xj3D<br /> * We will simply mirror the current xj3d.org repository, as version 2.0, and maintain full backwards compatibility by integrating any forthcoming changes there<br /> <br /> == Goals and Timeline ==<br /> <br /> We are considering how to further stabilize, improve and accelerate development of the Xj3D code base. This page is collecting ideas for potential improvement.<br /> <br /> These are familiar topics and lots of great work continues. It should be straightforward for interested stakeholders to discuss and agree on next steps.<br /> <br /> * Following comments from Xj3D source community and X3D working group from our teleconference on 30 June 2014, we plan to begin mirroring on SourceForge during the week of 7 July 2014.<br /> * Our goal is to have everything transitioned, stabilized, announced and ready for new contributions at the [http://www.web3d2014.org Web3D 2014 Conference] and [http://www.siggraph.org SIGGRAPH 2014 Conference] in Vancouver Canada, 8-10 and 11-14 August.<br /> <br /> == Source Code Hosting ==<br /> <br /> In order to achieve greater participation and development, the code needs to move to a stable public open-source repository. This will gain a lot more visibility among programmers who might want to contribute.<br /> <br /> * [http://www.xj3d.org xj3d.org] has hosted the source for many years but development has been intermittent and somewhat less than fully open.<br /> <br /> * The [https://savage.nps.edu/Savage/developers.html#Xj3D NPS branch of Xj3D] is used for experimental development. Proven changes and unit tests are integrated back into the Xj3D trunk when stable.<br /> <br /> '''Conclusion''': mirroring the full xj3d.org site on [https://sourceforge.net/projects/xj3d SourceForge Xj3D project] is our planned approach to meet group goals for unveiling and evangelizing Xj3D community opportunities at Web3D 2014 Conference and SIGGRAPH 2014.<br /> <br /> === SourceForge ===<br /> * The current xj3d.org code is in subversion, this can be migrated completely<br /> * Web3D already has numerous assets checked into the [https://sourceforge.net/projects/x3d Sourceforge X3D project], it is available<br /> * Sourceforge also has related projects for [https://sourceforge.net/projects/jgeom jgeom] and [https://sourceforge.net/projects/open-dis open-dis]<br /> * Multiple participants have experience with using and administering the Sourceforge site<br /> * Instead of using the Web3D X3D project, can Web3D instead create a new and separate Sourceforge project for Xj3D to keep things a bit simpler?<br /> * Can the new site maintain a side-by-side mirror of Xj3D.org and an refactored trunk, so that all updates are reliably accessible?<br /> * Can the new site keep a new trunk adjacent but separate so that new developers can get started quickly?<br /> * There is a lot of merit to using a version-control system that is familiar, especially as we try to integrate other Xj3D variants and prepare for SIGGRAPH milestones.<br /> <br /> === GitHub ===<br /> * GitHub includes the X3DOM project and a few other X3D-related projects.<br /> * We have reserved an [https://github.com/x3d X3D Xj3D] project site on GitHub as a placeholder. This might be useful for cross-links and future evolution.<br /> * The [https://github.com/pricing github pricing policy] does not cost money to operate an open-source organizational repository.<br /> * We are looking at migration of subversion to git.. appears possible but somewhat involved.<br /> * If we do migrate to GitHub, that will likely complicate the re-integration of other existing subversion-based exports of Xj3D.<br /> <br /> === Maven ===<br /> * [http://maven.apache.org Apache Maven] can encourage a variety of build possibilities and paired support between multiple projects, especially for Java<br /> <br /> == Web3D.org Website ==<br /> Several project builds are maintained on external repositories but their corresponding websites are automatically built and updated on [http://www.web3d.org web3d.org]<br /> <br /> === Web3D summary page ===<br /> <br /> * TODO: have ''www.web3d.org/xj3d'' (or somesuch) provide an official summary page for Xj3D community on new web3d.org website<br /> * TODO: find and cleanup or move other wiki pages for Xj3D<br /> <br /> === Mailing list updates ===<br /> <br /> Web3D Consortium maintains the mailing list archives.<br /> * Discussion list ''[http://web3d.org/mailman/listinfo/source_web3d.org source@web3D.org]'' is a misnomer and might be restarted as ''xj3d@web3d.org''<br /> * This list is also used for discussions on the SourceForge [https://sourceforge.net/projects/jgeom/?source=directory jgeom] project<br /> * Commits list ''[http://web3d.org/mailman/listinfo/source_web3d.org source_x3d_cvs@web3d.org]'' and commits account ''[http://web3d.org/mailman/listinfo/source_web3d.org cvs-user@xj3d.org]'' are also mis-named since subversion is used<br /> <br /> Alternative (and likely preferred) approach: move all discussion and reporting lists to the sourceforge repository in order to maximize community productivity. In that case, the prior email lists are simply closed and kept archived, which also reduces the web3d.org administrative burden.<br /> <br /> == Upcoming tasks ==<br /> <br /> === Merge modified Xj3D codebases ===<br /> <br /> Excellent improvements to Xj3D have occurred over the years that were never re-integrated into the version-controlled code base. We hope to capture these improvements.<br /> <br /> * [http://www.setareh.arch.vt.edu/safas/ Structure And Form Analysis System (SAFAS)], Nicholas Polys, Virginia Tech (VT) <br /> * [http://www.partdb.com PartDB Inc.], Hyokwang Lee<br /> * [https://github.com/Norkart/NK-VirtualGlobe Norkart/NK-VirtualGlobe], Rune Aasgaard<br /> <br /> * Others?<br /> <br /> === Xj3D issue tracking ===<br /> <br /> Currently two bugzilla sites are in existence.<br /> * [http://bugzilla.xj3d.org bugzilla.xj3d.org] (master)<br /> * [https://www.movesinstitute.org/bugzilla/buglist.cgi?quicksearch=xj3d NPS bugzilla] <br /> <br /> For maximum reliability over long term, we likely need to migrate to the SourceForge tickets tracker. Past bugs and issues can be transcribed as appropriate to maintain historical rationales.<br /> <br /> === Xj3D website improvements ===<br /> <br /> The [http://www.xj3d.org Xj3D website] is moderately complete but woefully out of date. <br /> <br /> Migration TODO: <br /> <br /> * Confirm that website pages and documentation are checked into version control<br /> * Automate website updates by synchronizing with version control<br /> * Offer ways for people to contribute bug reports, issues, improvements<br /> <br /> === Programming problems ===<br /> <br /> Several areas of Xj3D implementation are problematic. Dedicated attention and teamwork may help.<br /> <br /> * Better run-time exception reporting (most log entries are completely obscure)<br /> * Confirm updated jogl rendering is working, especially z-buffer and aliasing<br /> * Extrusion node (passes 7 of 10 tests)<br /> * Image rendering timing can miss colors/textures and hangs on numerous examples<br /> * Compressed binary encoding hangs on numerous examples, but the apparent list of exception errors seems short<br /> * Ensure that we are keeping current with [http://jogamp.org JOGAMP] (formerly java.net JOGL, includes JOAL JOCL etc.) and the [http://aviatrix3d.j3d.org Aviatrix3D] render layer ([https://github.com/j3d/aviatrix3d github]), administered by Justin Couch<br /> <br /> Other project efforts are welcome<br /> * [https://savage.nps.edu/X3D-Edit X3D-Edit] update report<br /> <br /> All inputs and contributions are welcome.
