```cs
public enum Maths.Maps.DiscMapping
```

Enumerates the various kinds of disc → square mapping algorithms.

## Values

| Name | Value | Description |
| --- | --- | --- |
| None | 0 | No conversion is performed. |
| Clip | 1 | No conversion is performed, although the mapping does limit itself to the interior of the space. |
| Stretch | 2 | Simple stretching of the interior spaces, resulting in a fairly discontinuous map. Especially along the diagonals squares will be squished into triangles. |
| Squircular | 3 | FG-Squircular mapping. Radial lines remain linear. |
| Elliptical | 4 | Elliptical grid mapping. A smoother version of Squircular but with non-orthogonal angles along the boundary. Radial lines become curved. |
| SchwarzChristoffel | 5 | A conformal mapping. |
