Xj3D is an open-source Java implementation for X3D. Xj3D has been used to demonstrate many capabilities, both for a variety of valuable projects and for specification development.
Goals and Timeline
We are considering how to further stabilize, improve and accelerate development of the Xj3D code base. This page is collecting ideas for potential improvement.
These are familiar topics and lots of great work continues. It should be straightforward for interested stakeholders to discuss and agree on next steps.
- After initial discussion on the email list, we will make this the subject of a weekly X3D working group teleconference (held Wednesdays 8-10am pacific)
- Our goal is to have everything transitioned, stabilized, announced and ready for new contributions at the Web3D 2014 Conference and SIGGRAPH 2014 Conference in Vancouver Canada, 8-10 and 11-14 August.
Source Code Hosting
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.
- xj3d.org has hosted the source for many years but development has been intermittent and somewhat less than fully open.
- The NPS branch of Xj3D is used for experimental development. Proven changes and unit tests are integrated back into the Xj3D trunk when stable.
- Web3D already has numerous assets checked into the Sourceforge X3D project
- Multiple participants have experience with using and administering this site
- The current code is in subversion, this can be migrated completely
- GitHub includes the X3DOM project and a few other X3D-related projects
- TODO: it appears that the github pricing policy costs money to operate an organizational repository
Web3D.org home page
Several project builds are maintained on external repositories but their corresponding websites are automatically built and updated on web3d.org
- TODO: should www.web3d.org/xj3d (or somesuch) become the official home of Xj3D?
Web3D Consortium maintains the mailing list archives.
- Discussion list source@web3D.org is a misnomer and can be restarted as email@example.com
- This list is also used for discussions on the SourceForge jgeom project
- Commits list firstname.lastname@example.org and commits account email@example.com are also mis-named since subversion is used
Merge modified Xj3D codebases
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.
- Virginia Tech (VT) Structure And Form Analysis System (SAFAS) system, Nicholas Polys
- PartDB Inc., Hyokwang Lee
Xj3D issue tracking
Currently two bugzilla sites are in existence.
For maximum reliability over long term, we likely need to migrate to the native issue tracker associated with whatever source host is chosen.
Xj3D website improvements
The Xj3D website is moderately complete but woefully out of date. TODO:
- Confirm that website pages and documentation are checked into version control
- Automate website updates by synchronizing with version control
- Offer ways for people to contribute bug reports, issues, improvements
Several areas of Xj3D implementation are problematic. Dedicated attention and teamwork may help.
- Confirm updated jogl rendering is working, especially z-buffer and aliasing
- Image rendering timing can miss colors/textures and hangs on numerous examples
- Compressed binary encoding hangs on numerous examples, but the apparent list of exception errors seems short
- Other project efforts are welcome
Discussion and consensus building
We are using firstname.lastname@example.org mailing list to work out these possibilities and build stakeholder consensus. All inputs and contributions are welcome.
