hi! my problem is the following: a have a quadtree lod algorithm, and I want to render multiple quads( so quads with different center point ) within one call, because I use index buffers, and I don''t want my vertices have to be transformed three-five times more than necessary. Is there any way for concatenating triangle fans like described in the ''Concatenating Triangle Strips'' article for strips? I tried to make the quads from strips, not fans; but there was more degenerating triangles than normal, visible ones. if anyone could help me, i''d very thankful.

nobody knows any solution????????

yes, I agree with you, and that was I thinking about. Now I''m going to make it

thanks for the reply.
