Method Detail

computeAverageDirection

public int computeAverageDirection(Vector3d dir,
                                   Point3d pos,
                                   double rad)

Computes the average direction in the vicinity of a point based on the line segments contained in a PolylineMesh. Returns the number of supporting line segments used for the calculation. If no segments were found, the method returns 0 and the direction is undefined.

Parameters:

dir - returns the normalized direction

pos - position at which direction should be computed

rad - radius of influence within which polyline mesh segments are considerd
