This is a revised version of the previous sketch "Point Vortices on the Sphere." I wanted to learn the rotation-operations for objects in 3D space in Processing. Accidentally, I got an artistic sketch! Please, enjoy ! You can change the view point using the mouse. ----- I implemented the symplectic integrator based on the following paper by Robert I. McLachlan, et.al: "Symplectic integrators for spin systems" Robert I. McLachlan, Klas Modin, and Olivier Verdier Phys. Rev. E 89, 061301(R) – Published 13 June 2014 -----
