Create a discrete mesh approximation of a surface.

Input parameters:

1. Sf → Surface to mesh.
2. Tl → Optional absolute tolerance to use during approximation.
3. Pl → If true, nice planar surfaces will result in the simplest possible meshes.
4. Jg → If true, meshes belonging to different surface faces will not be stitched together along edges.
5. Pr → If true, the mesh vertices will use high precision coordinates.
6. Rp → If true, attempts will be made to close the mesh if it isn't yet but should be.
7. E- → Optional minimum allowed edge length. This places a lower limit on the subdivision density.
8. E+ → Optional maximum allowed edge length. This places limits on the allowed size of long mesh edges.
9. Rf → If true, the initial sampling grid can be refined to better fit local conditions.
10. G- → Optional minimum number of quads in the initial sampling grid.
11. G+ → Optional maximum number of quads in the initial sampling grid.
12. As → Optional limits on the aspect ratio of quads in the initial sampling grid.
13. Ds → Optional density for subdivision surfaces.

Output parameters:

1. Ms → Mesh approximation of the surface.
