In my quest to optimize I read NVIDIA’s paper regarding VBOs.
There, one can read: “The “glVertexArray” function does a lot of setup in VBO, so to avoid redundancy, avoid calling it.”
so, if I were to do:
In the last case, where the drawing occurs, the binding explicit changes the pointers offsets?
If not, does binding make previous offset undefined?
In my actuall code I have two passes, where the offsets remain the samed from one pass to another and even for diferent VBOs during thoose passes. Then I figured that maybe the offsets in the second pass where doing nothing. I commented them and everything got screwed… Why? I can’t see any reason to, unless glBindBufferARB makes any previous indicated offsets invalid witch, after reading the ARB_vertex_buffer_object spec, seems wrong to me…
I would like very much for things to work like I wrote above… But it doesn’t seem that way.
