Point

module omega Two versions of the Point class exist. Point2 represents 2D points, and Point3 represents 3D points. Both have the same interface

Construct in the obvious way::

>>> p = Point3(1.0, 2.0, 3.0)
>>> p
Point3(1.00, 2.00, 3.00)

Point subclasses Vector, so all of Vector operators and methods apply. In particular, subtracting two points gives a vector::

>>> Point2(1.0, 2.0) - Point2(1.0, 0.0)
Vector2(0.00, 2.00)

The following methods are also defined:

intersect(other) For a 3D point, If other is a Sphere, returns True if the point lies within the sphere. For a 2D point, other must be a Circle

connect(other) Returns a LineSegment which is the minimum length line segment that can connect the two shapes. other may be a Point, Line, Ray, LineSegment, Sphere or Plane.

distance(other) Returns the absolute minimum distance to other. Internally this simply returns the length of the result of connect.
