DiffuseProbeResource
A resource containing baked diffuse lighting data organized as a tetrahedral probe mesh.
Declaration
class DiffuseProbeResourceOverview
Diffuse probe resources store spherical harmonic coefficients at discrete 3D positions, connected via a tetrahedral mesh for efficient runtime interpolation. This compact representation enables high probe density throughout a scene, allowing dynamic objects to receive accurate diffuse lighting as they move through different lighting conditions.
Probe Data Format
Each probe stores first-order (L0 + L1) spherical harmonics: 4 coefficients per RGB channel, for a total of 12 floats (48 bytes) per probe. The tetrahedral mesh adds minimal per-tetrahedron overhead. This compact representation enables high probe density within typical memory budgets.
