View Full Version : glDrawElements problem

07-02-2004, 09:42 AM
I work under WinXP. I have a strange problem. I use glDrawElementas to draw models. It works fine when indices are 0, 1, 2, 3, 4, etc. but when I write them in different order (when two vertices are identical I use only one and write the apropriate index) it renders some weird objects. Does anybody had the same problem or knows what's wrong?

I'm not exactly sure what you mean here. If you're drawing triangles, for example, then you can't just skip identical vertices; you must index all of them. Remember that you are sharing vertices, not indices. For strips, on the other hand, this should be possible, if you're careful about the order.
