RayTracingSubMeshFlags

enumeration

説明

Flags that determine the behavior of a sub-mesh in a RayTracingAccelerationStructure.

When RayTracingAccelerationStructure.AddInstance is called, a Renderer can be passed as argument. The Renderer's Mesh can have one or more sub-meshes. Use these flags to determine the behavior of individual sub-meshes when building an acceleration structure or when performing ray tracing.

See Also: RayTracingAccelerationStructure, MeshFilter.sharedMesh, Mesh.subMeshCount.

変数

DisabledUnity skips the sub-mesh when building a RayTracingAccelerationStructure. As a result, rays cast using TraceRay HLSL function will never intersect the sub-mesh.
EnabledThe sub-mesh is provided as input to a RayTracingAccelerationStructure build operation.
ClosestHitOnlyUnity considers this geometry opaque. This geometry responds to ray intersections as if it does not have an any hit shader.
UniqueAnyHitCallsEnable this flag to guarantee that the GPU only invokes the any hit shader once for each ray-triangle pair.
