Method Detail

reset

public void reset()

Description copied from interface: RotationTensor

Sets tensor to a condition of no rotation.

Specified by:

reset in interface RotationTensor

setAxial

public void setAxial(int i,
                     double theta)

Sets tensor for rotation about the indicated axis (0=x,1=y,2=z) by the given angle.

Specified by:

setAxial in interface RotationTensor

setRotationAxis

public void setRotationAxis(Vector v,
                            double theta)

Sets the tensor for rotation about the axis v by an angle theta.

invert

public void invert()

Description copied from interface: Tensor

Replaces this tensor with its inverse. The inverse is defined such that the tensor multiplied by its inverse gives the identity tensor.

Specified by:

invert in interface Tensor

Overrides:

invert in class Tensor3D

setQuaternions

public void setQuaternions(double[] q)

setOrientation

public void setOrientation(IOrientationFull3D orientation3D)

main

public static void main(java.lang.String[] args)

Method to test rotation tensor.
