Method Summary

Modifier and Type	Method and Description
Box3D	boundingBox()
PointSet3D	clip(Box3D box) Returns the clipped point, or null if empty.
boolean	contains(Point3D point) A point 'contains' another point if their euclidean distance is less than the accuracy.
double	distance(Point3D point) Gets the distance of the shape to the given point, or the distance of point to the frontier of the shape in the case of a plain shape.
boolean	equals(java.lang.Object obj)
double	getX()
