Parameters
| Name | Description |
|---|---|
| Rand | Random 2D point with components evenly distributed between 0 and 1 |
| Samples | Total number of samples that will be used |
| Intensity | Total intensity for light SamplePosition - Importance sampled 2D output texture coordinate (0-1) SampleColor - Representative color near Position from MIP level for SampleSize SampleIntensity - Intensity of individual points, scaled by probability and number of samples SampleSize - Local density of points near Position (scaled for 1x1 texture space) |
