Detailed Description

Occupancy system configuration constants. Tile-based occupancy for efficient empty space skipping.

Memory Layout (1080p): TileCount: 120 × 68 tiles (W/16 × H/16) StepSlices: 32 (128 steps / 4) Occupancy Texture: 120 × 68 × 32 = 261,120 texels Per-texel: uint4 (128 bits for 128 volumes) Total Memory: ~8.4 MB (View + Light)
