This method override makes the camera behave like a regular object, so it doesn't stay focused at the same point when it moves:
CL3D.CameraSceneNode.prototype.calculateViewMatrix = function () {
this.getAbsoluteTransformation().getInverse(this.ViewMatrix);
this.recalculateViewArea()
};
This adds a 'move' method to SceneNodes, so you can more easily move in the direction it is facing:
CL3D.SceneNode.prototype.move = function(x, y, z) {
var aim = new CL3D.Vect3d();
aim.X = x;
aim.Y = y;
aim.Z = z;
this.getRelativeTransformation().rotateVect( aim );
this.Pos.X += aim.X;
this.Pos.Y += aim.Y;
this.Pos.Z += aim.Z;
}
