Class Point

java.lang.Object
  Point

public class Point
extends java.lang.Object

Represents a point in three-dimensional coordinates.

Field Summary

static Point

ORIGIN The origin point, with zero for all coordinates.

Method Summary

Point	add(Vector v) Returns a copy of this point shifted by the given * vector.
Point	addScaled(double scalar, Vector v) Returns a copy of this point shifted by the given vector scaled by the given scalar.
static Point	create(double x, double y, double z) Constructs a point with the given coordinates.
double	getDistanceTo(Point other) Returns the distance between this point and the parameter point.
double	getX() Returns the x-coordinate of this point.
double	getY() Returns the y-coordinate of this point.
double	getZ() Returns the z-coordinate of this point.
Vector	subtract(Point other) Returns the vector from the parameter point to this point - ie, one whose components are the difference of this vector's coordinates and the parameter vector's coordinates.
java.lang.String	toString()
