I have been experimenting with digital terrain model files in ESRI ASCII grid raster format. Despite zero experience with this type of data I found it very easy to load into R, as per code below. The
plot3D function from the
rasterVis package defaults to a nice looking plot but the model is rather reflective. Given that it's supposed to be a landscape this shiny surface is not really appropriate. EDIT: I am looking for a more natural (if such a word can be used about a 3D rendering of a set of figures), matt, topological plot.
I imagine there must be ways around this but I have no experience using
raster and would much appreciate some pointers. So my question is: how can I reduce or remove the reflectivity of the plot?
library(raster) library(rgdal) library(rasterVis) foo <- raster(readGDAL("my.dtm.asc")) plot3D(foo)
