Z fighting?

Heh, this post reminds me of some kind of an asian poem or something. Either that or im just tired and need to go to bed.

But anyway that’s Z-Fighting like jwatte said. Try using PolygonOffset. Or even the stencil buffer; that can help this problem. I think the FAQ on this site talks about this if i remember correctly.


he says he doesn’t move the camera but there is shaking. Maybe things aren’t rendering consistently at each call to render?
