public class Generic3dMatrix

extends java.lang.Object

A generic 3d matrix class that implements rotation about the principal axis, translation, and scaling

Constructor Summary

Generic3dMatrix()
Creates a new instance of fGeneric3dMatrix

Method Summary

void	concatRx(double ax) multiplies a rotation about the X-axis i.e.
void	concatRy(double ay) multiplies a rotation about the Y-axis i.e.
void	concatRz(double az) multiplies a rotation about the Z-axis i.e.
void	concatS(double sx, double sy, double sz) multiplies scaling
void	concatT(double x, double y, double z) multiplies a transform
void	makeIdentity() creates or resets the matrix
