public Matrix3D()

Create a new unit matrix

Method Detail

scale

public void scale(double f)

Scale by f in all dimensions

Parameters:

f - DOCUMENT ME!

scale

public void scale(double xf,
                  double yf,
                  double zf)

Scale along each axis independently

Parameters:

xf - DOCUMENT ME!

yf - DOCUMENT ME!

zf - DOCUMENT ME!

translate

public void translate(double x,
                      double y,
                      double z)

Translate the origin

Parameters:

x - DOCUMENT ME!

y - DOCUMENT ME!

z - DOCUMENT ME!

yrot

public void yrot(double theta)

rotate theta degrees about the y axis

Parameters:

theta - DOCUMENT ME!

xrot

public void xrot(double theta)

rotate theta degrees about the x axis

Parameters:

theta - DOCUMENT ME!

zrot

public void zrot(double theta)

rotate theta degrees about the z axis

Parameters:

theta - DOCUMENT ME!

mult

public void mult(Matrix3D rhs)

Multiply this matrix by a second: M = MR

Parameters:

rhs - DOCUMENT ME!

unit

public void unit()

Reinitialize to the unit matrix

transform

public void transform(Atom atom)

DOCUMENT ME!

Parameters:

atom - DOCUMENT ME!

transform

public void transform(double[] v,
                      int[] tv,
