In geometry, a torus (pl.: tori or toruses) is a surface of revolution generated by revolving a circle in three-dimensional space one full revolution about an axis that is coplanar with the circle. The main …

Go to Surface Area or Volume. A torus is a fascinating 3D shape that looks like a donut or swim ring. It is created by revolving a smaller...

Dec 22, 2025 · An (ordinary) torus is a surface having genus one, and therefore possessing a single "hole" (left figure). The single-holed "ring" torus is known in older literature as an "anchor ring."

Aug 3, 2023 · What is a torus in geometry. Learn how to find its surface area and volume with solved examples and diagrams.

Torus: Definition A Torus (plural: tori) is a geometric surface, generated by the revolution of a circle of radius R; The revolution occurs a distance r away from a center point.

The torus, a shape as familiar as a donut yet as rich in complexity as the most intricate mathematical concepts, holds a unique place in the study of mathematics.

The torus is the surface generated by the revolution of a circle (C) around a line (D) of its plane; it is therefore a tube with constant diameter and circular bore.

May 26, 1999 · A torus is a surface having Genus 1, and therefore possessing a single `` Hole.'' The usual torus in 3-D space is shaped like a donut, but the concept of the torus is extremely useful in …

A torus (plural: tori or toruses) is a tube shape that looks like a doughnut or an inner tube. In geometry, a torus is made by rotating a circle in three dimensional space. To make a torus, the circle is rotated …

The torus is perhaps the least used object in real modelling applications but it still appears as a standard form in modelling and rendering packages ahead of far more useful geometric primitives.
