Constructor Detail

Vector3D

Vector3D(double x,
         double y,
         double z)

Method Detail

add

Vector3D add(Vector3D a)

sub

Vector3D sub(Vector3D a)

scale

Vector3D scale(double k)

dot

double dot(Vector3D a)

cross

Vector3D cross(Vector3D a)

rotate

Vector3D rotate(Vector3D axis,
                double angle)

rotArray

static void rotArray(Vector3D[] v,
                     Vector3D[] u,
                     double azimuth,
                     double elevation,
                     double angle)

rotates an array of vectors.

same

boolean same(Vector3D a,
             double epsilon)

pole

static Vector3D pole(double r,
                     Vector3D a,
                     Vector3D b,
                     Vector3D c)

Compute the polar reciprocal of the plane containing a, b and c. If this plane does not contain the origin, return p such that dot(p,a) = dot(p,b) = dot(p,b) = r. Otherwise, return p such that dot(p,a) = dot(p,b) = dot(p,c) = 0 and dot(p,p) = 1.
