1:49:55psychomaniactv Q: I've been looking into existing approaches to assign items to cells for clustered shading. I've already implemented two of them, but now I'd like to try iD's approach. They mention in their SIGGRAPH slides that an item shape can be an OBB or a frustum and they test its planes against the cells in clip space since a cell will simply be an AABB there. I should really improve my math knowledge / skills but I currently don't know how to do this. Can you point me in the right direction?

2:03:33sopvop Q: I see that transient_state has only four task_with_memory, and game uses much more threads. So the threads may sit there without work because you can only submit at most four such tasks per frame to queue. Isn't four tasks a bit low, or am I missing something here?

2:04:52psychomaniactv Q: Thanks for answering. The way I understand their slides is they have a convex shape defined by its boundary planes (either a 6-plane OBB or a 5-plane frustum) and they test it against an AABB in clip space. The AABB is already in clip space and the planes come from world space. I have no idea how to test for intersection in clip space. What even happens to the planes when they are transformed?
