Hi All,
As far as I understand it, both glBufferDataARB and glMapBufferARB provide alternate ways for me to get my vertex, texture coordinates, etc... data into VBO's.
My data is dynamic, i.e. could change every frame. I've been using glBufferDataARB quite well so far, but was wondering if i'm missing out on possible speed gains that glMapBufferARB may provide. From what i've read, i'm not, and infact I can't understand why glMapBufferARB even exists. If anything, it is slower than glBufferDataARB, because you need to make three calls map, put data, unmap as apposed to just one with glBufferDataARB.
I hope someone can enlighten me to the error of my thoughts, or confirm them.
Thanks,
Stephen
