Sd Instance Mapping Ptr

Synthetic Data node to expose the scene instances semantic hierarchy information

Installation

To use this node enable omni.syntheticdata in the Extension Manager.

Inputs

Name	Type	Descripton	Default
Cuda Ptr (inputs:cudaPtr)	bool	If true, return cuda device pointer instead of host pointer	False
Exec (inputs:exec)	execution	Trigger	None
Render Results (inputs:renderResults)	uint64	Render results pointer	0
Semantic Filer Tokens (inputs:semanticFilerTokens)	token[]	Tokens identifying the semantic filters applied to the output semantic labels. Each token should correspond to an activated SdSemanticFilter node	[]
