CullResults

struct in UnityEngine.Experimental.Rendering

Description

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.
visibleOffscreenVertexLights	Off screen lights that still effect visible Scene vertices.
visibleReflectionProbes	Array of visible reflection probes.
visibleRenderers	Visible renderers.

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.
GetLightIndexMap	If a RenderPipeline sorts or otherwise modifies the VisibleLight list, an index remap will be necessary to properly make use of per-object light lists.
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.
SetLightIndexMap	If a RenderPipeline sorts or otherwise modifies the VisibleLight list, an index remap will be necessary to properly make use of per-object light lists. If an element of the array is set to -1, the light corresponding to that element will be disabled.

Cull	Perform culling for a Camera.
GetCullingParameters	Get culling parameters for a camera.
