The first nine va lues, T1–T9, descr ibe rotation and
scaling. The last three, T10–T12, describe a move,
in world coordinates.

Omni Li ght Comman d
Controls the location and color of an Omni light.
The first parameter is the name of the light. This is

The last parameter, <shadow flag>, parameter is 1
if the light casts shadows, 0 otherwise.
Spotl ight Command
Controls the location, color , and other
characteristics of a target spotlight.

The <hot angle> parameter is the angle of the
light’s hot spot, in degrees.
The < fa lloff angle> parameter is the falloff angle,
in degrees
The <shadow flag> par ameter is 1 if t he light casts
shadows, 0 otherwise.
Orthogonal V iewport Commands
These commands render a particular view—top,
bottom, left, rig ht, front, or back.
The<x>,<y>,<z>parametersarethecoordinates
of the center of the view.
The <width> parameter is the width of the
rendered image, in world units.
User Viewport Command
Renders the user view.
The<x>,<y>,<z>parametersarethecoordinates
of the center of the view.
The <hor i z> parameter is the horizontal angle,
in degrees.
The <vert> parameter is the vertical angle, in
degrees.
The < roll> parameter is a placeholder for the roll
angle—but this is an "empty," unused parameter
that must always be zero. To use roll in a VUE file,
use a camera view instead of a u s er view.
The <width> parameter is the width of the
rendered image, in world units.
Camera View Command
Renders a camera view.
