ExamplesYou can use the "page up" and "page down" keys to flip through the scene files in the current directory in alphabetical order.basic-train The big 3D train layout I used for the picture on the front page. Try turning off all textures except texture 0. basic-train2 The elevated train layout I used during development. basic-geom A basic 3D geometry layout. basic-maze Once I thought of this, I couldn't resist making one as a proof of concept. More Examples The examples are organized into folders; folder names are in parentheses.
Geometry Examples (geom, geomx) single-X (single) This is reference material, but it can be fun to look at. For every shape in the library files there's a corresponding "single-X" file that displays just that one shape. Most of them are self-explanatory.
rtetra - right-angled tetrahedron with vertices at the origin and the unit vector endpoints Fun geometry facts: If you think of the vertices and edges of a cube as forming a graph, that graph can be colored with just two colors. If you take the vertices of one color and make a shape out of them, you get an inscribed tetrahedron ("itetra"). The same construction in 4D gives you an inscribed hexadecachoron ("ihexadeca"). There were two colors, so there are two inscribed tetrahedra and two inscribed hexadecachora. However, if you make a shape out of the face centers of a tesseract, you get … another hexadecachoron! And if you make that hexadecachoron exactly twice as large, then it's the same size as the other two, because 22 = 12+12+12+12. Each hexadecachoron has eight vertices. If you make a shape out of all three sets of eight at once, you get … a 24-cell! It can't be colored with two colors, but because it's made of vertices from three hexadecachora and is self-dual, it can be colored with three colors in a nice symmetrical way. scene This is just an old scratch file of mine.
