Return Value

A reference to the current TLAS.

Parameters

Name	Description
blas	The bottom-level acceleration structure that contains the geometries of the instance.
transform	The transformation matrix applied to the instance geometry.
id	The instance ID used in shaders to identify the instance.
hitGroupOffset	An offset added to the shader-local data for a hit-group shader record.
mask	A user defined mask value that can be used to include or exclude the instance during a ray-tracing pass.
flags	The flags that control the behavior of the instance.
