# Geodesics

### One solution of Euler’s Rigid equation###

A good solve should preserve the momentum and energy. The solver for the following animation is done by algorithm introduced in this paper

### One geodesic on a revolutional ellipzoid

### Another geodesic on the same revolutional ellipzoid

### Different geodesics on the surface $ f(x, y) = exp(-\frac{x^2}{2}-y^2)$
