Web5 de fev. de 2012 · 2 Answers. The strip primitive does the right thing with respect to backface culling. You can think of the tris' winding order as being managed so that the order is consistent for each triangle in the strip - e.g. you can think of the GPU rendering (0,1,2), (2,1,3) ... All triangles in triangle strip maintain same direction/winding order. WebI've enabled face culling with glEnable(GL_CULL_FACE), and I'm trying to cull the back faces, but whenever I do glCullFace(GL_BACK) nothing gets rendered. If I do …
