    Re: Official feedback on OpenGL 3.2 thread

    No, I don't want that. I want a modification of glBufferData/glBufferSubData that will not copy the data right away but will return immediately and then the driver will wait for the GPU buffer to be...

    Re: Official feedback on OpenGL 3.2 thread

    Which will cause glTexImage not to return untill the copying is done. Which is another thing that I want to avoid. And then there is glTexSubImage, which depending on how the driver works may stall...

    Re: Official feedback on OpenGL 3.2 thread

    Straightforward usage pattern? Mapping a buffer to update data will most certainly lead to sync issues. Even discarding the buffer with glBufferData(, NULL) and updating the whole thing might not...

    Ok, then lets call it glBufferDataRetained / glBufferSubDataRetained.

    Currently sending data to VBO (or any other buffer data object) works like this:
    1. Allocate and fill the data
    2. Give it to...

    Re: Official feedback on OpenGL 3.2 thread

    Are there plans to use ARB_sync with VBOs?

    For instance after calling glBufferData - the data will not be copied immediately, and it can be safely changed or deleted only after the sync object is...
