- This program generates user definable stars as DECLARED
- "COMPOSITES" for DKB (currently 2.05AB) Ray-Tracing program in .DAT
- format. Actually, it should have been for "OBJECTS" but I didn't want
- to hold up sending it out any longer. A two dimensional outline is
- drawn on the screen as the .DAT is generated.
-
- See also SHADE (which generates pleated lamp shades) and DIAMOND
- (which generates a cut gem, plus creates the rest of the .DAT file:
- view, light, floor). With all of these programs, just play around with
- the variables to generate new shapes. For example, generating many
- long points on the star looks like the spokes of a bicycle wheel. Many
- short points on a large radius star looks like a circular saw blade.
- Use your imagination and please post any ideas or neat works for the
- world to enjoy.

- Enclosed are three files:
-
- STAR.BAS Quickbasic
- STAR.EXE MS-DOS executable
- STAR.DOC This file
- STAR000.TGA First frame of spinning star animation
-
-
- The program will ask the following questions:
-
- {Example values, but not used below}
- Number of points: 8
- Point Top from center: 20
- Point Bottom from center: 5
- Point Joint from center: 10
- Thickness from center: 5
-
- The following diagrams are a visual attempt to describe what each
- question means.
