| positions | 用于计算探针的世界空间位置的数组。 |
| 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. |
