Summary
| Description | Illustration of toroidal coordinates, which are obtained by rotating the two-dimensional bipolar coordinates about the axis separating its two foci, which are at distance 1 from the vertical z-axis. The red sphere is the σ=30° isosurface, the blue torus is the τ=0.5 isosurface, and the yellow half-plane is the φ=60° isosurface. The green half-plane marks the x-z plane, from which φ is measured. The black point is located at the intersection of the red, blue and yellow isosurfaces, at Cartesian coordinates roughly (0.996, -1.725, 1.911). |
