Point3f
public Point3f()
Constructs and initializes a Point3f to (0,0,0).
Point3f
public Point3f(float x,
float y,
float z) Constructs and initializes a Point3f from the specified xy coordinates.
x - the x coordinatey - the y coordinatez - the z coordinate
Point3f
public Point3f(Point3d p1)
Constructs and initializes a Point3f from the specified Point3d.
p1 - the Point3f containing the initialization x y z data
Point3f
public Point3f(Point3f p1)
Constructs and initializes a Point3f from the specified Point3f.
p1 - the Point3f containing the initialization x y z data
Point3f
public Point3f(Tuple3d t1)
Constructs and initializes a Point3f from the specified Tuple3d.
t1 - the Tuple3d containing the initialization x y z data
Point3f
public Point3f(Tuple3f t1)
Constructs and initializes a Point3f from the specified Tuple3f.
t1 - the Tuple3f containing the initialization x y z data
Point3f
public Point3f(p[] )
Constructs and initializes a Point3f from the specified array.
distance
public final float distance(Point3f p1)
Returns the distance between this point and point p1.
- the distance between these two points
distanceL1
public final float distanceL1(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) .
distanceLinf
public final float distanceLinf(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)].
distanceSquared
public final float distanceSquared(Point3f p1)
Computes the square of the distance between this point and point p1.
- the square of distance between these two points as a float
project
public final void project(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.
p1 - the source Point4d, which is not modified
