  "Description": "Create surface forms from matrix or 'raster' data for\nflexible plotting and conversion to other mesh types. The\nfunctions 'quadmesh' or 'triangmesh' produce a continuous\nsurface as a 'mesh3d' object as used by the 'rgl' package. This\nis used for plotting raster data in 3D (optionally with\ntexture), and allows the application of a map projection\nwithout data loss and many processing applications that are\nrestricted by inflexible regular grid rasters. There are\ndiscrete forms of these continuous surfaces available with\n'dquadmesh' and 'dtriangmesh' functions.",
