GLUT provides function glutSolidTorus to render a Solid Torus and glutWireTorus to render a Wire Frame Torus. glutSolidTorus and glutWireTorus render a solid or wireframe torus (doughnut) respectively centered at the modeling coordinates origin whose axis is aligned with the Z axis. Here are the syntax of both the above functions
void glutSolidTorus (GLdouble innerRadius, GLdouble outerRadius, GLint nsides, GLint rings);
void glutWireTorus (GLdouble innerRadius, GLdouble outerRadius, GLint nsides, GLint rings);
Where, innerRadius –> Inner Radius of the Torus, outerRadius –> Outer Radius of the Torus, nsides –> Number of sides for each radial section, rings –> Number of radial divisions for torus.
