Points on Curve

Given a bundle containing curve data and a u-value (between zero and one), get a point on the curve and the curve tangent at that point. Note that if multiple curves are present in the bundle, only the first one will be used.

Installation

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

Inputs

Name	Type	Description	Default
Curves Bundle (curvesBundle)	bundle	Bundle containing curves data
U-Values (uValues)	float[]	Parametric values from zero to one at which to sample points on the curve
Sampling Mode (samplingMode)	int	Sampling mode: 0 – sample from an input array connect to the uValues input, 1 – sample from a random distribution generated using the timeBasedSeed, randomSeed, and numberOfPoints inputs	0
Vary Randomness Over Time (timeBasedSeed)	bool	If true, random seed will vary with time; if false random numbers will be the same each frame.	False
Random Seed (randomSeed)	int	Seed for random number generator for u-value distribution (if nothing is connected to the uValue input)	0
Number of Points (numberOfPoints)	int	Number of points to randomly sample on the curve (if nothing is connected to the uValue input)	10

Outputs

Name	Type	Description	Default
Point on Curve (points)	float[3][]	Point on input curve
Tangent at Point (tangents)	float[3][]	Curve tangent at point
