Dear all,
I have a question regarding to update texture data on iPhone using OpenGL ES. Basically the two naive ways to do it are:
1) generate a new texture when I need to with glTexImage2D calls,
2) create a texture and udpate use glTexSubImage2D calls.
Although the performances now are all not yet satisfying. On PC platforms, I know PBO should be performing better, although does OpenGL ES 2.0 on iPhone supports PBO? Also, for my situation, which has the best performance updating texture data (very frequently, let's say one update per frame).
Thanks a lot in advance!
