RayTracingAccelerationStructure

class in UnityEngine.Experimental.Rendering

描述

A data structure used to represent the geometry in the Scene for GPU ray tracing.

Creates a RayTracingAccelerationStructure with the given RayTracingAccelerationStructure.Settings.

AddInstance	Adds a ray tracing instance associated with a Renderer to the RayTracingAccelerationStructure.
Build	在 GPU 上构建 RayTracingAccelerationStructure。
ClearInstances	Removes all ray tracing instances from the acceleration structure.
CullInstances	Populates the acceleration structure with ray tracing instances associated with Renderers in the Scene using various filtering and culling parameters.
Dispose	销毁此 RayTracingAccelerationStructure。
GetInstanceCount	Returns the number of ray tracing instances in the acceleration structure.
GetSize	Returns the total size of this RayTracingAccelerationStructure in GPU memory in bytes.
Release	另请参阅：RayTracingAccelerationStructure.Dispose。
RemoveInstance	Removes a ray tracing instance from this RayTracingAccelerationStructure.
UpdateInstanceID	Updates the instance ID of a ray tracing instance associated with the Renderer passed as argument.
UpdateInstanceMask	Updates the instance mask of a ray tracing instance associated with the Renderer passed as argument.
UpdateInstancePropertyBlock	Updates per ray tracing instance Material properties.
UpdateInstanceTransform	Updates the transformation of a ray tracing instance.
