Free gallery of gifs of geometric ringsIn geometry, a ring is also called a toroid, and is defined as the surface of revolution around an axis that generates a polygon in a closed curve.
All the gifs of geometric rings in this free gallery to use as you like 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 = 2?RA, 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.
