Hey. Now comes a non-trivial one... :-)
A while ago I added support for primitive restart to our internal build to stitch triangle strips - this greatly improved performance and VRAM usage for our very heavy CAD data. As primitive restart was included in GL core a while a ago I suppose this feature has a chance to be included in OSG. I havn't prepared a patch yet (mostly because I don't want to waste the time in case this isn't going to be integrated anyway), so I'll just outline what I did: - osg::DrawElements and friends got two new attributes, PrimitiveRestart (bool) and PrimitiveRestartIndex (unsigned integer) - osg::State was extended to allow setting the respective GL attributes - The osg::PrimitiveFunctor and osg::PrimitiveIndexFunctor interfaces were extended by a primitiveRestart() and setPrimitiveRestart(bool, unsigned int) method - osg::TriangleIndexFunctor was extended to implement the new functionality ... and all other PrimitiveFunctor / PrimitiveIndexFunctor implementations everywhere were extended to support primitive restart. (I also have a visitor stitching strips which are contained in seperate primitive sets but I did that outside of OSG ... if PS support is included I suspect it might be useful to have a visitor to do this in osgUtil somewhere too) So... should I prepare a patch?
