The toroids, or just torus are geometric figures donut shaped in three dimensions. On the plane, this figure is called annulus. The volume of a ring is obtained with the formula V = 2πRA, where A is the area of the figure and the offset R. You can get a toroid from any figure, not only of polygons, and sometimes rings with curious shapes are obtained. These images show some hoops 3D with different types of movements.
