The near and far clipping planes are specified by near and far. Various distortion artifacts may appear when using a perspective projection, since Flash players only have a 2D matrix. Some of these can be quite disturbing. Defines the viewer's position in polar coordinates. Azimuth defines the azimuthal angle in the x-y plane, measured from the y axis.
Incidence specifies the angle of incidence in the y-z plane, measured from the z axis.
The incidence angle is the angle of the viewport relative to the z axis. Twist defines the amount that the viewpoint is to be rotated around the line of sight using the right-hand rule. Twist controls a rotation along the viewer's z axis. Push the current transformation matrix onto the stack. Restore a previous transformation matrix.
