Module propagate 

Structs

PropagationConfig

Configuration for light propagation.

SHCoeffs

SH coefficients for propagation (2nd order, 9 coefficients).

Constants

PROPAGATE_COMP_SRC

Embedded compute shader for GPU propagation.

Functions

flux_through_face

Compute outgoing flux through a face based on SH-weighted radiance.

gather_from_neighbors

Gather incoming light from 6 neighbors.

propagate_hierarchical

Propagation on octree levels (hierarchical).

propagate_light

Run multiple iterations of light propagation on a voxel grid.

propagate_step

Single propagation step: read from source grid, write to dest grid.
