Creates an implicitly defined manifold for a 2-torus embedded in 3-space, centered at (x,y,z) with inner radius RI and outer radius RO. If RO were 0. (don't! the eqs are singular then), the torus would be a circle of radius RI in the xy-plane. You are free to set RI<RO, but it won't look like a torus.
- Parameters:
-
| x | The x coordinate of the center of the torus |
| y | The y coordinate of the center of the torus |
| z | The z coordinate of the center of the torus |
| RI | The inner radius. |
| RO | The outer radius. |
| e | A place to return errors. |
- Returns:
- An implicitly defined manifold.
