Detailed Description

The Matrix4x4 class defines a four by four matrix container. Matrix4x4 objects can be instantiated in the scripting environment.

m = new Matrix4x4(); // create empty matrix
raxis = new Vector3d( 0,0,1 ); // create new axis Vector3d
m.rotateDegrees( 90, raxis ); // rotate matrix 90 degrees on z axis
m.scale( 2.0, 1.0, 2.0 ); // scale matrix non-uniformly
