scatter points

Scatters points on the input geometry with optional curve regions

Installation

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

Inputs

Name	Type	Description	Default
active	bool	Is the Scatter Points node currently active?	True
exclusive	bool	If this is true, it outputs the point cloud prim and the input bundles, otherwise only the point cloud prim	True
rotations	bool	If this is true, it output the rotations.	True
rotation	float[3]	Rotate the point in x,y,z.	[0, 0, 0]
rotationRandom	float[3]	Randomly rotate the particle in x,y,z along a range.	[0, 0, 0]
scales	bool	If this is true, it output the scales.	True
scale	float[3]	Change the size of the point in x,y,z.	[5, 5, 5]
scaleRandom	float	Randomly change the size of the point in x,y,z.	0.0
objectIndices	bool	If this is true, it output the object indices.	True
objectIndex	int	Object index is valid if you have multiple sources to output. this number corresponds with the order you imported your sources.	0
objectIndexRandom	int	Randomly pick an ‘Object Index’ source in a range.	0
normals	bool	If this is true, it output the object indices.	True
tangents	bool	If this is true, it output the object indices.	True
binormals	bool	If this is true, it output the object indices.	True
debugDraw	bool		False
debugDrawCurveTriangulation	bool		False
playbackEvaluation	bool	If this is true, time for the simulation is from the timeline, not real time.	False
filterUsingCamera	bool	If true, scattered points will be discarded if they are occluded by scattering geometry or are outside the viewing frustum of the provided camera prim.	False
useScatterGeometryAsOcclusionGeometry	bool	If true, prims connected to the ‘prim’ input of this node will also be used to occlude points when filtering using a camera. Otherwise, prims connected to the ‘occlusionPrim’ input will be used.	True
playbackStartFrame	int	If ‘playbackEvaluation’ is true, this is the frame after which the simulation will start.	0
usdTimecode	double	The USD timecode at the current playback point (timeline time ‘*’ timecodes/sec)	0
time	double	Either the running clock or the timeline time or timeline time, depending on playbackEvaluation	0
randomSeed	uint64		0
scatterOnSurface	bool	If this is true, points will be generated on the surface of the input mesh(es).	True
scatterInsideVolume	bool	If this is true, points will be generated inside the input mesh(es).	True
scatterAcrossPoints	bool	If this is true, points will be generated at the vertices of the input mesh(es).	True
numDesiredPoints	int	The number of generated points desired.	100
curveTessellation	int	curve tessellation factor	10
prim	bundle	Mesh geometry to use for point scattering
occlusionPrim	bundle	Geometry to use for occlusion test
cameraPrim	bundle	Camera prim
curvesBundle	bundle	Input curve data

Outputs

Name	Type	Description	Default
projectedPoints	float[2][]	If a camera prim is provided, this collection will be populated with points projected into the camera’s screen space in the range [-1, 1]. If no camera prim is provided, this will be empty.	[]
bundle	bundle	output bundle of points data
