Methods

o scale 
 void scale(float f)
Scale by f in all dimensions

o scale 
 void scale(float xf,
            float yf,
            float zf)
Scale along each axis independently

o translate 
 void translate(float x,
                float y,
                float z)
Translate the origin

o yrot 
 void yrot(double theta)
rotate theta degrees about the y axis

o xrot 
 void xrot(double theta)
rotate theta degrees about the x axis

o zrot 
 void zrot(double theta)
rotate theta degrees about the z axis

o mult 
 void mult(Matrix3D rhs)
Multiply this matrix by a second: M = M*R

o unit 
 void unit()
Reinitialize to the unit matrix

o transform 
 void transform(float v[],
                int tv[],
                int nvert)
Transform nvert points from v into tv. v contains the input coordinates in floating point. Three successive entries in the array constitute a point. tv ends up holding the transformed points as integers; three successive entries per point

o toString 
 public String toString()
Overrides:
toString in class Object
