Culling results (visible objects, lights, reflection probes).
In a scriptable render loop, the rendering process is typically doing culling for each camera (CullResults.Cull), followed by rendering subsets of visible objects (RenderLoop.DrawRenderers) and processing visible lights (visibleLights, visibleReflectionProbes).
CullResults also provides several functions to aid shadow rendering (ComputeDirectionalShadowMatricesAndCullingPrimitives, ComputeSpotShadowMatricesAndCullingPrimitives, ComputePointShadowMatricesAndCullingPrimitives).
| visibleLights | Array of visible lights. |
| visibleReflectionProbes | Array of visible reflection probes. |
| ComputeDirectionalShadowMatricesAndCullingPrimitives | Calculates the view and projection matrices and shadow split data for a directional light. |
| ComputePointShadowMatricesAndCullingPrimitives | Calculates the view and projection matrices and shadow split data for a point light. |
| ComputeSpotShadowMatricesAndCullingPrimitives | Calculates the view and projection matrices and shadow split data for a spot light. |
| FillLightIndices | Fills a compute buffer with per-object light indices. |
| GetLightIndicesCount | Gets the number of per-object light indices. |
| GetShadowCasterBounds | Returns the bounding box that encapsulates the visible shadow casters. Can be used to, for instance, dynamically adjust cascade ranges. |
| Cull | Perform culling for a Camera. |
| GetCullingParameters | Get culling parameters for a camera. |
