Bounding Box 3D

This node outputs the 3D bounding box data.

Installation

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

Inputs

Name	Type	Description	Default
exec	execution	Trigger
primPaths	token[]	Prim paths corresponding to each bounding box.
sdIMNumSemantics	uint	Number of semantic entities in the semantic arrays
sdIMSemanticTokenMap	token[]	Semantic array of token of size numSemantics ‘*’ numSemanticTypes containing the mapping from the semantic entities to the semantic entity path and semantic types
sdIMMinSemanticIndex	uint	Semantic id of the first instance in the instance arrays
sdIMSemanticWorldTransform	float[]	Semantic array of 4x4 float matrices containing the transform from local to world space for every semantic entity
data	uchar[]	Buffer array data	[]
filteredBboxInfo	uchar[]	Buffer array data containing the index of 3D bbox which are in the viewport.	[]
semanticOcclusion	uchar[]	occlusion ratio of each semantic bounding box. If a prim contains semantic children, the value is -1.	[]
semanticMapPtr	uint64	Array pointer of numSemantics uint16_t containing the semantic index of the semantic prim first semantic prim parent
semanticTypes	token[]	Semantic Types to consider	[‘class’]
bufferSize	uint	Size (in bytes) of the buffer (0 if the input is a texture)
swhFrameNumber	uint64	Frame number

Outputs

Name	Type	Description	Default
exec	execution	Trigger
data	uchar[]	Extent data of bounding box.
ids	uint[]	Unoccluded semantic ids of the bounding box.
labels	token[]	Semantic labels of the bounding box.
primPaths	token[]	Prim paths corresponding to each bounding box.
bboxIds	uint[]	Identifier associated with bounding box, used to link different types of bounding boxes to the same (eg. 2D Tight and 3D)
swhFrameNumber	uint64	Frame number
bufferSize	uint	Size (in bytes) of the buffer (0 if the input is a texture)
height	uint	Shape of the data
width	uint	Shape of the data
