SetGlobalRayTracingAccelerationStructure(string, RayTracingAccelerationStructure)
Adds a command to bind the RayTracingAccelerationStructure object to all shader stages.
public void SetGlobalRayTracingAccelerationStructure(string name, RayTracingAccelerationStructure accelerationStructure)
Parameters
The name of the acceleration structure in shader code.
The acceleration structure to set.
Remarks
This command binds a RayTracingAccelerationStructure object to all shader stages. You can use the structure for inline ray tracing (ray queries) or as an argument in calls in ray tracing shaders. The RayTracingAccelerationStructure object must be built using the CommandBuffer.BuildRayTracingAccelerationStructure method before calling this command.
TraceRayRay queries can be used to perform acceleration structure traversal and geometry intersection tests. To access this functionality, the HLSL code must be compiled using the directive or by using the built-in shader keyword (for example, #pragma multi_compile _ UNITY_DEVICE_SUPPORTS_INLINE_RAY_TRACING).
#pragma require inlineraytracingUNITY_DEVICE_SUPPORTS_INLINE_RAY_TRACINGAdditional Resources: Shader.SetGlobalRayTracingAccelerationStructure, SystemInfo.supportsRayTracingShaders, SystemInfo.supportsInlineRayTracing.
SetGlobalRayTracingAccelerationStructure(int, RayTracingAccelerationStructure)
Adds a command to bind the RayTracingAccelerationStructure object to all shader stages.
public void SetGlobalRayTracingAccelerationStructure(int nameID, RayTracingAccelerationStructure accelerationStructure)
Parameters
The name ID of the acceleration structure in shader code. Use Shader.PropertyToID to get this value.
The acceleration structure to set.
