Toposcape is a simulator of a ball rolling over different types of surfaces. The surfaces are modelled using NURBS and a manual engine to move the ball over a series of them.
Toposcape comes equipped with various examples of distinct surface types, and depending on each one, the ball will move and roll in a different way; it is ideal to do topographic experiments and simulate different terrain types. Once you load any of these examples, you just have to indicate the start speed of the ball and see its behaviour over that terrain.
You can watch the rolling of the ball in Toposcape from different perspectives, and zoom in on it to see it better.
