You simply use the image as a texture map for the DEM
surface. You can do this directly with cgSurface.
Here is an example:

file = Filepath(Subdir=['examples','data'],'elev_t.jpg')
Read_JPEG, file, image
file = Filepath(Subdir=['examples','data'],'elevbin.dat')
dem = Read_Binary(file, Data_Dims=[64,64], Data_Type=1)
cgSurface, dem, Texture_Image=image

Cheers,

David
