Returns

true if the nearest point on Ray to some curve in the set passed the PointWithinToleranceTest.

Parameters

Parameter	Description
Ray	query ray
ResultOut	populated with information about successful nearest point result
PointWithinToleranceTest	should return true if two 3D points are "close enough" to be considered a hit
