Hi all,
i would be interested if it is possible to share the memory allocated by glMapBuffer(…) with another application.
Idea is, since this is - in a few lucky cases - VRAM memory, on could avoid a costly extra copy from ‘regular’ shared memory to texture / vertex etc memory using own glTexSubImageXY.
In short, is it possible to declare memory allocated elsewhere ( gl driver ) later as ‘shared’?
Best,
Hendrik
