IFS Polyhedron Viewer
This demo displays polyhedral models that are defined as indexed face sets. A few of the models have assigned colors for the faces (just the house, cube, tetrahedron, and octohedron). The others get random colors which will be different each time the demo runs.
You can drag on the polyhedron to rotate it.
This demo does not use lighting, which means that it is lacking one of the major components of realistic 3D graphics. The edges and differently colored faces give some hint of 3D. Try setting the faces to white and setting the drawing to edges only; You will see a flat white blob with no hint of 3D at all.
Try switching between Perspective and Orthographic projection. The difference is not huge in this case, but note that with a perspective projection, things look bigger when they are close to the viewer.
