CullResults

struct in UnityEngine.Experimental.Rendering

Switch to Manual

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).

Variables

visibleLightsArray of visible lights.
visibleOffscreenVertexLightsOff screen lights that still effect visible scene vertices.
visibleReflectionProbesArray of visible reflection probes.
visibleRenderersVisible renderers.

Public Functions

ComputeDirectionalShadowMatricesAndCullingPrimitivesCalculates the view and projection matrices and shadow split data for a directional light.
ComputePointShadowMatricesAndCullingPrimitivesCalculates the view and projection matrices and shadow split data for a point light.
ComputeSpotShadowMatricesAndCullingPrimitivesCalculates the view and projection matrices and shadow split data for a spot light.
FillLightIndicesFills a compute buffer with per-object light indices.
GetLightIndexMapIf a RenderPipeline sorts or otherwise modifies the VisibleLight list, an index remap will be necessary to properly make use of per-object light lists.
GetLightIndicesCountGets the number of per-object light indices.
GetShadowCasterBoundsReturns the bounding box that encapsulates the visible shadow casters. Can be used to, for instance, dynamically adjust cascade ranges.
SetLightIndexMapIf 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.

Static Functions

CullPerform culling for a Camera.
GetCullingParametersGet culling parameters for a camera.
