 public Point3d(double x,
                double y,
                double z)

Constructs and initializes a Point3d from the specified xyz coordinates.

Parameters:

x - the x coordinate

y - the y coordinate

z - the z coordinate

 public Point3d(double p[])

Constructs and initializes a Point3d from the specified array.

Parameters:

p - the array of length 3 containing xyz in order

 public Point3d(javax.vecmath.Point3d p1)

Constructs and initializes a Point3d from the specified Point3d.

Parameters:

p1 - the Point3d containing the initialization x y z data

 public Point3d(javax.vecmath.Point3f p1)

Constructs and initializes a Point3d from the specified Point3f.

Parameters:

p1 - the Point3d containing the initialization x y z data

 public Point3d(javax.vecmath.Tuple3d t1)

Constructs and initializes a Point3d from the specified Tuple3d.

Parameters:

t1 - the Tuple3d containing the initialization x y z data

 public Point3d(javax.vecmath.Tuple3f t1)

 public final double distanceSquared(javax.vecmath.Point3d p1)

Computes the square of the distance between this point and point p1.

Parameters:

p1 - the other point

Returns:

the square of distance between these two points as a float

 public final double distance(javax.vecmath.Point3d p1)

Returns the distance between this point and point p1.

Parameters:

p1 - the other point

Returns:

the distance between these two points as a float

 public final double distanceL1(javax.vecmath.Point3d p1)

Computes the L-1 (Manhattan) distance between this point and point p1. The L-1 distance is equal to abs(x1-x2) + abs(y1-y2).

Parameters:

p1 - the other point

 public final double distanceLinf(javax.vecmath.Point3d p1)

Parameters:

p1 - the other point

 public final void project(javax.vecmath.Point4d p1)

Multiplies each of the x,y,z components of the Point4f parameter by 1/w and places the projected values into this point.

Parameters:

p1 - the source Point4d, which is not modified
