Detailed Description

Abstract class that draws torus on the screen. It stores generic data describing the drawn torus:

its radii,
number of points used to model it,
ID of a program associated with it,
ID of a vertex array object in which pointers to the corrresponding data are stored. Derived classes must determine a way of initializing vertex attribute arrays and drawing the torus model.
