nearestPointOnCurve

Go to: Related nodes. Attributes.

This node returns the closest point of an (x,y,z) point (attribute "inPosition") to a curve (given by the attribute "inputCurve"). You can query the closest (x,y,z) point (attribute "position") or you can query the closest curvep parameter (attribute "parameter").
