Constructs and initializes a Point3d from the specified xyz coordinates.
o Point3d(double[])
Constructs and initializes a Point3d from the array of length 3.
o Point3d(Point3d)
Constructs and initializes a Point3d from the specified Point3d.
o Point3d(Point3f)
Constructs and initializes a Point3d from the specified Point3f.

Method Index

o distance(Point3d)
Returns the distance between this point and point p1.
o distanceL1(Point3d)
Computes the L-1 (Manhattan) distance between this point and point p1.
o distanceLinf(Point3d)
Computes the L-infinite distance between this point and point p1.
o distanceSquared(Point3d)
Returns the square of the distance between this point and point p1.
o project(Point4d)
Multiplies each of the x,y,z components of the Point4f parameter by 1/w and places the projected values into this point.

Constructors

o Point3d 
 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
o Point3d 
 public Point3d(double p[])
Constructs and initializes a Point3d from the array of length 3.

Parameters:
p - the array of length 3 containing xyz in order
o Point3d 
 public Point3d(Point3d p1)
Constructs and initializes a Point3d from the specified Point3d.

Parameters:
p1 - the Point3d containing the initialization x y z data
o Point3d 
 public Point3d(Point3f p1)
Constructs and initializes a Point3d from the specified Point3f.

Parameters:
p1 - the Point3f containing the initialization x y z data
o Point3d 
 public Point3d()
Constructs and initializes a Point3d to (0,0,0).

Methods

o distanceSquared 
 public final double distanceSquared(Point3d p1)
Returns the square of the distance between this point and point p1.

Parameters:
p1 - the other point
Returns:
the square of the distance
o distance 
 public final double distance(Point3d p1)
Returns the distance between this point and point p1.

Parameters:
p1 - the other point
Returns:
the distance
o distanceL1 
 public final float distanceL1(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) + abs(z1-z2).

Returns:
the L-1 distance
o distanceLinf 
 public final float distanceLinf(Point3d p1)
Computes the L-infinite distance between this point and point p1. The L-infinite distance is equal to MAX[abs(x1-x2), abs(y1-y2), abs(z1-z2)].

Returns:
the L-infinite distance
o project 
 public final void project(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
