title: Implementing a Texture atlas, with triangle_strip or triangles. iPhone opengl es
body: <p>Multiple places recommend using a texture atlas for performance. Apple suggest the function gltexcoordpointer. In my example I have a row of squares each one is given a random texture. I put all the random textures into the super-texture. Now the problem is I can't seem to create a texcoordarray. I can't find any information on how gltexcoordpointer assings the selected sub-texture to the vertex coords. The vertexes would ideally be drawn using triangle_strip, but triangles will work as well.</p>
