Constructor Detail

Vector3d

public Vector3d(float x1,
                float y1,
                float z1,
                float x2,
                float y2,
                float z2)

Create a vector, described by two points.

Vector3d

public Vector3d(Coord3d p1,
                Coord3d p2)

Create a vector, described by two coordinates.

Method Detail

vector

public Coord3d vector()

Return the vector induced by this set of coordinates.

dot

public float dot(Vector3d v)

Compute the dot product between and current and given vector. Reminnd that the dot product is:

• 0 if vectors are perpendicular

Parameters:

v - input vector

Returns:

the dot product

cross

public Coord3d cross(Vector3d v)

Computes the vectorial product of the current and the given vector. The result is a vector defined as a Coord3d, that is perpendicular to the plan induced by current vector and vector V.

norm

public float norm()

Compute the norm of this vector.

Returns:

the norm

distance

public double distance(Coord3d c)

Compute the distance between two coordinates.

getCenter

public Coord3d getCenter()

Return the central point of this segment.
