- Model File Format:
- ==================
-
- Model files are simple text files containing the coordinates and color
- of each polygon. Model files must have the extension .j3d to be
- accepted by the jaw3d Model Viewer. The general format is:
-
- <number of points of polygon> <color of polygon>
- <x1> <y1> <z1>
- <x2> <y2> <z2>
- <x3> <y3> <z3>
-
- For example:
-
- 4 1
- -10 10 0
- 10 10 0
- 10 -10 0
- -10 -10 0
-
- This will draw a blue rectangle. A rectangle has four vertices, therefore
- the 4. The color code for blue is 1.
- You must use the following coordinate system:
-
- +Y
- | /
- | /
- -------|------- +X
- / |
- / |
- +Z
-
- The larger you make the polygons the greater is the chance that they will
- overlap incorrectly. Therefore, if you see any overlapping problems,
- simply divide your polygons up into smaller ones and the problems should
- disappear. Especially polygons that are supposed to be covered up by
- others should be divided up like this.
-
- Note: empty lines in model files will create problems. For seperation or
- comments, use the # character. Do NOT place comments between coordinate lines,
- only between individual polygon sections.
-
- Here is a partial list of color codes. There are 256 different colors you
- can use. This list contains only the few colors of which I know the names!
-
- BLACK 0
- DARKGRAY 8
- BLUE 1
- LIGHTBLUE 9
- GREEN 2
- LIGHTGREEN 10
- CYAN 3

- LIGHTGRAY 7
- WHITE 15

- + zoom in
- - zoom out
- up move the model up
- down move the model down
- left move the model left
- right move the model right
