etopo

<p>A simplified version of 'Etopo2'. The Etopo2 data set was
reduced 20X to create this raster layer of global relief. See code
in 'data-raw/topo.R'.</p>

datasets

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.
