A shader for GPU ray tracing.

This shader should contain at least a raygeneration shader.


maxRecursionDepthThe maximum number of ray bounces this shader can trace (Read Only).

Public Methods

DispatchDispatches this RayTracingShader.
SetAccelerationStructureSets the value for RayTracingAccelerationStructure property of this RayTracingShader.
SetBoolSets the value of a boolean uniform.
SetBufferBinds a ComputeBuffer or GraphicsBuffer to a RayTracingShader.
SetConstantBufferBinds a constant buffer created through a ComputeBuffer or a GraphicsBuffer.
SetFloatSets the value of a float uniform.
SetFloatsSets the values for a float array uniform.
SetIntSets the value of a int uniform.
SetIntsSets the values for a int array uniform.
SetMatrixSets the value of a matrix uniform.
SetMatrixArraySets a matrix array uniform.
SetShaderPassSelects which Shader Pass to use when executing ray/geometry intersection shaders.
SetTextureBinds a texture resource. This can be a input or an output texture (UAV).
SetTextureFromGlobalBinds a global texture to a RayTracingShader.
SetVectorSets the value for a vector uniform.
SetVectorArraySets a vector array uniform.

Inherited Members


hideFlagsShould the object be hidden, saved with the Scene or modifiable by the user?
nameThe name of the object.

Public Methods

GetInstanceIDReturns the instance id of the object.
ToStringReturns the name of the object.

Static Methods

DestroyRemoves a GameObject, component or asset.
DestroyImmediateDestroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoadDo not destroy the target Object when loading a new Scene.
FindObjectOfTypeReturns the first active loaded object of Type type.
FindObjectsOfTypeGets a list of all loaded objects of Type type.
InstantiateClones the object original and returns the clone.


boolDoes the object exist?
operator !=Compares if two objects refer to a different object.
operator ==Compares two object references to see if they refer to the same object.
