I think the challenges are mostly on OpenSCAD side, like consolidating
all the scattered places where model render is happening.
One of the biggest questions is if there's a nice abstraction layer for
the OpenGL stuff. While there are a number of projects doing that, e.g.
OpenSceneGraph, Ogre, Irrlicht, ... but most tend to be more targeted
at games which does not fit too nicely with OpenSCAD. OpenSceneGraph
might be a reasonable choice, but it's a huge project in itself, so it
could be a challenge to integrate. It is available in MXE which we use
for Windows builds, so that's a big plus.
Actually the newly released Qt5.4 does bring some more relatively low
level OpenGL abstractions, so maybe that's all we need.
Still an engine that supports things like Camera, 3D interactions and
ideally even with support for GLES2 would help a lot.
