Closest Point on Curve

Given a reference point and a bundle containing curve data, get the closest point on the curve to the reference point along with the curve tangent and u-value (between zero and one) 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
Point (point)	float[3]	Reference point for which we want to find the closest point on the input curve(s)

Outputs

Name	Type	Description	Default
Point on Curve (point)	float[3]	Closest point on input curve(s) to specified reference point
Tangent at Point (tangent)	float[3]	Curve tangent at closest point on curve
U Value (uValue)	float	Parametric value of closest pont on curve
