Constructor Detail

Matrix3D

Matrix3D()

Create a new identity matrix

Method Detail

scale

void scale(float f)

Scale by f in all dimensions

scale

void scale(float xf,
           float yf,
           float zf)

Scale along each axis independently

translate

void translate(float x,
               float y,
               float z)

Translate the origin

yRotate

void yRotate(double theta)

rotate theta degrees about the y axis

xRotate

void xRotate(double theta)

rotate theta degrees about the x axis

zRotate

void zRotate(double theta)

rotate theta degrees about the z axis

multiply

void multiply(Matrix3D rhs)

Multiply this matrix by a second: M = M*R

identity

void identity()

Reinitialize to the identity matrix

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

toString

public java.lang.String toString()

Overrides:
