Page 13 of 17		 CREATING SMALLER DATA FILES

The Endpoint and Line commands can be very verbose and redundant, so there are
three other commands -- Set, EndpointList, and LineList -- that you can use to
create smaller data files.  The Set command sets options that are common to a
group of endpoints or lines, and the EndpointList and LineList commands
eliminate the need to enter the X, Y, Z, Name, Color, and Layer keywords for
each piece of data.  Using these commands, and eliminating the comments, the
data file for the triangle might look like this:

Set Z 10.1
EndpointList X Y Name
-10.5 0 BottomLeft 10.4 0 BottomRight 0.2 10 Top
LineList From To Color Layer
BottomLeft Top 10 0 BottomRight Top 11 1 BottomLeft BottomRight 12 2

			       DEFINING POINTS

Analogous to endpoints and lines, you can define single pixel points in your
data file using the Point and PointList commands.  You define each point with
five pieces of information: its x, y, and z coordinates, its color, and its
layer.	The following object, a spiral galaxy, has 500 points in two colors on
two layers.
