Hi,
I know there are plenty of topics relating to this, but no one exactly matches what I actually want to know.
Typical setup: One thread rendering from a VBO, another updating it.
Now what I don't know for example:
Is the VBO locked automatically so only one thread can use it at one time?
And if it is not synchronized: manually always blocking the whole VBO makes no sense to me. Because it is quite big but there's always only a tiny piece of it being modified by the update thread. Is there an automatic way to block parts of a VBO? Or do I have to split the big one into several smaller VBOs and block them by myself, when necessary?
Thanks for every answer!
