I have a (GPU) Buffer that contains the World Position and Extents of Local Cubemaps aswell as a TextureArray that contains the textures of the Cubemaps. The Bounds of the Local Cubemaps are Axis Aligned, there is no rotation involved.

How do I figure out which and how much cubemaps affect a single pixel (in a pixel shader), when Extents can overlap (arbitrary deep)?

  • \$\begingroup\$ What do these cubemaps represent in this case? Are they reflection probes, or something else? \$\endgroup\$ Commented Aug 14, 2023 at 13:11
  • \$\begingroup\$ @DMGregory yes, they are for reflections \$\endgroup\$ Commented Aug 14, 2023 at 13:18
