How should I go about doing occlusion culling with glDrawElements? I am dealing with voxel-like terrain. I want to avoid drawing the faces that are facing another block. I just don't know how to incorporate this with glDrawElements. Should I even use glDrawElements?

glEnable(GL_CULL_FACE); glCullFace(GL_BACK); – MickLH Jun 20 '14 at 00:31
Will it work without having to add implementation with my camera? – badcc Jun 20 '14 at 00:35
You aren't talking about back-face culling, per your edit. You are talking about occlusion culling. – Jun 20 '14 at 00:52
Ah, that is a helpful term. Thank you very mush, Josh! – badcc Jun 20 '14 at 01:51
