c++ - OpenGL ES 2D scene, multiple scene graph trees for different elements -


within opengl es project debating whether create scene graph gui , separate 1 actors. allow me control gui system , transform without effecting scene , vice versa.

as long have separate transforms, can control them independently of each other.
