Method Summary

void	rotate(double[] pivot, double phi, double theta, double psi) rotate - Rotate the object around the specified point by phi about the z-axis followed by theta round the y-axis followed by psi around the z-axis.
void	translate(double[] distance) translate - Translate this object by the distance specified.

Method Detail

rotate

void rotate(double[] pivot,
            double phi,
            double theta,
            double psi)

rotate - Rotate the object around the specified point by phi about the z-axis followed by theta round the y-axis followed by psi around the z-axis. These is the standard Euler angle rotation. The rotation matrix is...

[	cos(phi)*cos(th)*cos(psi)-sin(phi)*sin(psi)	-sin(phi)*cos(th)*cos(psi)-cos(phi)*sin(psi)	sin(th)*cos(psi)	]
[	sin(phi)*cos(psi)+cos(phi)*cos(th)*sin(psi)	-sin(phi)*cos(th)*sin(psi)+cos(phi)*cos(psi)	sin(th)*sin(psi)	]
[	-cos(phi)*sin(th)	sin(th)*sin(phi)	cos(th)	]

Parameters:

pivot - double[] - a three-vector specifying the point around which the rotation is performed

phi - double

theta - double

psi - double

translate

void translate(double[] distance)

translate - Translate this object by the distance specified.

Parameters:

distance - double[] - A three-vector specifying how much to translate
