qm_as_raster

Approximate re-creation of a raster from a quadmesh.

Create surface forms from matrix or 'raster' data for flexible plotting and
conversion to other mesh types. The functions 'quadmesh' or 'triangmesh'
produce a continuous surface as a 'mesh3d' object as used by the 'rgl'
package. This is used for plotting raster data in 3D (optionally with
texture), and allows the application of a map projection without data loss and
many processing applications that are restricted by inflexible regular grid rasters.
There are discrete forms of these continuous surfaces available with
'dquadmesh' and 'dtriangmesh' functions.
