| Parameter | Description | 
|---|---|
| positions | The array of world space positions used to evaluate the probes. | 
| tetrahedronIndices | The array of tetrahedron indices that guide interpolation. Start with values of 0 and reuse results between frames for faster lookup. | 
| lightProbes | The array of light probes where the resulting lighting is written to. | 
| occlusionProbes | The array of occlusion probes where the resulting occlusion is written to. | 
Calculate light probes and occlusion probes at the given world space positions.
