Computes the oriented distance from a point to the plane. The distance is:
positive if the point lies above the plane (relative to the plane normal)
zero if the point is on the plane
negative if the point lies below the plane (relative to the plane normal)
Parameters:
p - p the point to compute the distance for
Returns:
the oriented distance to the plane
public int closestAxisPlane()
Computes the axis plane that this plane lies closest to.
Geometries lying in this plane undergo least distortion (and have maximum area) when projected to the closest axis plane. This provides optimal conditioning for computing a Point-in-Polygon test.
