[R-sig-Geo] transforming a 3d SpatialGridDataFrame into a mesh of some kind

[Robert J. Hijmans]

Mark,

If spgdf is a SpatialGridDataFrame object

# install.packages("raster", repos="http://R-Forge.R-project.org")
library(raster)
plot3D(raster(spgdf))

Or you can have a look at the code:
getMethod("plot3D", 'RasterLayer')
