Maybe you know the lib called "kgllib" developped by rivo lakes. I take a lot of stuff from it to create gluon KGL. kgllib provides many same class as us :
GLTexture => KGLTexture
GLShaders => KGLShaders GLWidget=> KGLView and more... For the most part, there are more complete as gluon/KGL.
Kgllib provides an easy way to create 3d mesh, camera ... that can not gluon:KGL. Inversaly gluon::KGL use items and item's manager by KGLEngine. And physics....
So, I think, we should make a fusion between both projects. It's not hard to make KGLItem with kgllib. And it will more easy to use ODE on it.... That's a hard refactoring... but not impossible... So currently it's just a thinking of myself.. I just want to say, I couldn't do it alone.... !
