This PR improves the accuracy of volumetric attenuation calculations and removes artificial distance limitations for more physically correct rendering.
Changes:
Remove min() clamp in volume_lighting.slangh for physically correct attenuation
Use actual hit distances instead of artificially clamped distances
Improve plane distance calculation using actual hit positions in volume_composite_helpers.slangh
Better handling of rays extending beyond froxel grid maximum distance
Add explanatory comments for architectural decisions
Benefits:
More physically accurate volumetric attenuation
Better visual quality for distant light sources in volumetric scenes
Eliminates inconsistencies between infinite and finite ray handling
