Basically I need to optimise my code allot. I’m trying to use a single super texture with all my textures in it and just one draw call. For simplicity the problem comes down to this. I have 3 squares squares in a row that are connected. There are 8 vertexes, 4 of which are shared, triangle_strip seems the best method to draw them but I could just use triangles. The super texture is just a square split into 4 squares. I want to assign the squares a texture at random.
From what I’ve read gltexcoordpointer assigns the tex coords to the vertex points, so it’s not possible do what I want due to the shared vertexes? This seems wrong since I see people talking about using texture atlases everywhere.
I guess my question is equivalent to how to draw a cube with a different texture on each side using a single texture file. (the choice of the texture on each side is chosen at runtime).
