I’ve got a question about the usage of VBOs. One can allocate memory when calling glBufferDataARB. But what happens if I call this function twice for the same buffer (maybe with another size)? Is the old memory freed or do I have to worry about that by myself?
I haven’t found an explanation for this question so far… Maybe somebody knows something about that.
Sorry, I just found the answer in the specs. But I can swear that it wasn’t there berfore!
