Project proposed and commenced in August 2017. Goal is to produce a software component which will encourage support of X3D in commercial and open source applications, particularly for those applications that already support VRML import/export. This project will test and demonstrate the proposition that "X3D is VRML", or "VRML is X3D".
This target audience for this software component is developers, and the goal is to give them a tool to improve X3D support in their applications without the need for expertise in the X3D standard itself. This project will leverage the idea that if an application already supports VRML then the task of mapping an X3D scenegraph into the application logic has already been performed and support of X3D (XML encoding) should be straightforward. Likewise, if an application supports the XML encoding it should be straightforward to add support for VRML encoding.
It is recognized that there are already translators and conversion tools to convert ClassicVRML encoding to XML Encoding. This project is essentially a repackaging of those codes into a readily deployable library. One motivation of this project is the discussion with potential users in the medical 3D printing community, through DICOM Working Group 17. Among users who may be classified as managers and project managers:
- The structure of the X3D standard as an abstract standard with multiple encodings is a complication which does not add value for them. In their view, there are two file formats: X3D, which is the XML encoding of the X3D standared; and VRML, which can either mean the Classic VRML encoding of the X3D standard, or it can mean a file conforming to an earlier version of the VRML standard.
- There is a strong preference for native import/export of files in required formats over conversions of existing or created files.
For any commercial or open source application which currently supports either VRML or X3D import and export
- To the extent allowed by an application's support of a X3D Profiles and version, content can be imported into the application through both ClassicVRML encoding and XML Encodings.
- The application can export to both ClassicVRML encoding and the XML Encoding
- Pre X3D standard versions of the VRML standard are supported as possible. The hope is to at least support Interchange Profile content, with well defined and documented failure modes to encourage developers to upgrade their applications support for X3D scenegraph
