So much has changed since the last release.
- Maths is now 100% catered to by MathGL++, see the SF page for that excellent project.
- OpenGL state is managed by StateGL++.
- Image loading & texturing by ImgGL++
Only the core parts are left that define the scene graph structure. The graph is multi parent, multi child like Performer.
Loadable addons define geometry and transforms as well as render modes and caching.
This lean mean new version of TGL is miles beyond the old releases. The first release will be mainly to check that everything compiles and runs OK. Please test it out, you might just like it :-).
