class in UnityEngine.Rendering
/
Implemented in:UnityEngine.CoreModule
A data structure used to represent the geometry in the Scene for GPU ray tracing.
Additional resources: CommandBuffer.SetRayTracingAccelerationStructure, RayTracingShader.SetAccelerationStructure.
| RayTracingAccelerationStructure | Creates a RayTracingAccelerationStructure with the given RayTracingAccelerationStructure.Settings. |
| AddInstance | Adds a ray tracing instance to the RayTracingAccelerationStructure. |
| AddInstances | Adds an array of ray tracing Mesh instances to the RayTracingAccelerationStructure. |
| AddInstancesIndirect | Adds an array of ray tracing instances to the RayTracingAccelerationStructure where the instance matrices are specified using a GraphicsBuffer. |
| AddVFXInstances | Adds the ray tracing instances associated with a VFXRenderer to the RayTracingAccelerationStructure. |
| Build | Builds acceleration structures on the GPU. Allocates any GPU memory required for storing acceleration structure data. |
| ClearInstances | Removes all ray tracing instances from the RayTracingAccelerationStructure. |
| CullInstances | Populates the RayTracingAccelerationStructure with ray tracing instances that Unity associates with Renderers in the Scene by using filtering and culling parameters. |
| Dispose | Destroys this RayTracingAccelerationStructure and frees the GPU memory used for storing acceleration structure data. |
| GetInstanceCount | Returns the number of ray tracing instances in the RayTracingAccelerationStructure. |
| GetSize | Returns the total size of this RayTracingAccelerationStructure in GPU memory in bytes. |
| Release | Destroys this RayTracingAccelerationStructure and frees the GPU memory used for storing acceleration structure data. |
| RemoveInstance | Removes a ray tracing instance associated with a Renderer from this RayTracingAccelerationStructure. |
| RemoveInstances | Removes ray tracing instances from the RayTracingAccelerationStructure using filtering based on layer and RayTracingMode. |
| RemoveVFXInstances | Removes the ray tracing instances associated with a VFXRenderer from the RayTracingAccelerationStructure. |
| UpdateInstanceID | Updates the instance ID of a ray tracing instance. |
| UpdateInstanceMask | Updates the instance mask of a ray tracing instance. |
| UpdateInstancePropertyBlock | Updates per ray tracing instance Material properties. |
| UpdateInstanceTransform | Updates the transformation of a ray tracing instance. |
