    Thanks again, Dark Photon. I think we should conclude that the assumption with OpenGL primitives doesn't hold and generates undefined behavior unless stated otherwise. The description is too unsharp...
  3. Difference between coherent and volatile qualifier

    Hi,

    I am currently trying to understand the differences between the coherent and volatile qualifier. First, some quotes (in code tags for a better formatting) from the ARB_shader_image_load_store...

    Thanks so far, Dark Photon.

    That quote from the GLSL 4.4 spec you underlined is the point which keeps me puzzled.



    What is their definition of a primitive? Is it a GPU primitive (triangle)...
  5. Defined behaviour of image load after store in a different shader stage?

    Hi,

    imagine following scenario:

    - I want to draw indexed triangle strips with a primitive restart after every fourth index (restart index: 0xffffffff) which results in quads.
    - Then I want to...
