## Rendering methods

Main purpose of V_Sim is to render some file describing positions and other informations n a graphical way. This is achieved implementing #RenderingMethods. Currently two methods exist, one draw spheres (or other geometric forms such as cubes) on defined positions. The other is a more specialised version of the former, adding a direction information on each position. Ths method is called SpiRendering and is usefull to render spin configurations.
