• 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)$
