Bill Currie	f282bfc045	[vulkan] Use occlusion queries for culling lights ... The info isn't used yet, but this shows that vulkan's occlusion queries are at least somewhat useful. However, the technique isn't perfect: infinite radius lights (1/r and 1/r^2) are difficult to cull, and all lights can poke through thin enough walls, and then lights containing the camera get culled incorrectly (will need a separate test). Still, it looks like it will help once everything is tied together.	2023-12-17 18:45:02 +09:00
Bill Currie	44c1ef5968	[vulkan] Correct the size of cone splats ... I really don't know what I was thinking when I wrote that code. Maybe I was trying for a half angle. Now the rendered "cone" matches up with a hard-clipped cone light (soft edges stick out a bit).	2023-08-08 16:00:24 +09:00
Bill Currie	bf951c3ba2	[vulkan] Get debug light objects working again ... And also get them working for infinite radius lights.	2023-08-06 00:20:25 +09:00
Bill Currie	85128a3e86	[vulkan] Rework lighting to use splats ... It's currently slower, and the cone splats are buggy, but the lighting code itself got some nice cleanups.	2023-06-28 01:01:56 +09:00
