comment How to texture a surface generated by marching cubes algorithm?
A problem I'm having with this approach is selecting the correct texture for each vertex, given multiple options. You can't simply select the texture of the closest voxel to that vertex, since "air" voxels have no texture. In the air case, you have to resolve to another voxel, and I'm racking my brain in an attempt to come up with something efficient. You can't simply map an air voxel to another voxel for all vertices, so you must either encode more specific logic, OR use a lookup table somehow. Hmm...

comment Why does this geometry shader slow down my program so much?
Does the exception for point sprites generalize to shaders of layout(points) in;? Or is it the fixed output size? Or perhaps both?

comment Hardware instancing for voxel engine
Voxel engines being "hard to work with" and "silly tech demos" is inappropriate, overly subjective, and broad. The asker didn't ask whether making a voxel engine is a good idea or not.
