A torus is the 3D shape of a donut or ring. It is formed by rotating a circle of radius r around an axis at distance R from the circle's centre. The inner hole appears when R > r.
Công thức
- R
- radius of the tube itself — radius of the tube itself
Hướng dẫn từng bước
- 1R = distance from the centre of the tube to the centre of the torus
- 2r = radius of the tube itself
