SdInstanceMappingPtr

Synthetic Data node to expose the scene instances semantic hierarchy information

Installation

To use this Node, you must enable omni.syntheticdata in the Extension Manager.

Inputs

Name	Type	Description	Default
exec	execution	Trigger
renderResults	uint64	Render results pointer
semanticFilerTokens	token[]	Tokens identifying the semantic filters applied to the output semantic labels. Each token should correspond to an activated SdSemanticFilter node	[]
cudaPtr	bool	If true, return cuda device pointer instead of host pointer	False
