fm_mesh_2d_map

fm_mesh_2d_map_lim

Calculates coordinate mappings for spherical <code>fm_mesh_2d</code> projections.
This is an internal function not intended for general use.

internal

Generate planar and spherical triangle meshes,
compute finite element calculations for 1- and 2-dimensional flat and curved
manifolds with associated basis function spaces, methods for lines and
polygons, and transparent handling of coordinate reference systems and
coordinate transformation, including 'sf' and 'sp' geometries. The core
'fmesher' library code was originally part of the 'INLA' package, and
implements parts of "Triangulations and Applications" by
Hjelle and Daehlen (2006) <doi:10.1007/3-540-33261-8>.
