 public Point3f(float x,
                float y,
                float z)

Constructs and initializes a Point3f from the specified xy coordinates.

Parameters:

x - the x coordinate

y - the y coordinate

z - the z coordinate

 public Point3f(float p[])

Constructs and initializes a Point3f from the specified array.

Parameters:

p - the array of length 3 containing xyz in order

 public Point3f(javax.vecmath.Point3f p1)

Constructs and initializes a Point3f from the specified Point3f.

Parameters:

p1 - the Point3f containing the initialization x y z data

 public Point3f(javax.vecmath.Point3d p1)

Constructs and initializes a Point3f from the specified Point3d.

Parameters:

p1 - the Point3f containing the initialization x y z data

 public Point3f(javax.vecmath.Tuple3f t1)

Constructs and initializes a Point3f from the specified Tuple3f.

Parameters:

t1 - the Tuple3f containing the initialization x y z data

 public Point3f(javax.vecmath.Tuple3d t1)

 public final float distanceSquared(javax.vecmath.Point3f 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

Parameters:

p1 - the other point

Returns:

the distance between these two points

 public final float distanceL1(javax.vecmath.Point3f 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) .

Parameters:

p1 - the other point

 public final float distanceLinf(javax.vecmath.Point3f 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)].

Parameters:

p1 - the other point

 public final void project(javax.vecmath.Point4f 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
