The program converts the models from the original Stunts (1990) into the format
compatible with this game. The original models contain lines and polygons. The
3D graphical functions used in this game require only triangles. To convert the
models from game1.txt and game2.txt, first compile stconv.c:

gcc stconv.c -o stconv -lm -Wall -W

Then:

./stconv game1.txt
mkdir sdata1
mv *.geo sdata1/
mv *.col sdata1/

./stconv game2.txt
mkdir sdata2
mv *.geo sdata2/
mv *.col sdata2/

The already converted models, which were slighly adjusted, are available in
directories ../../sdata1/ and ../../sdata2. They can be viewed with view3d or
simple3d from:
