I am using GRASS 7.0 on ubuntu linux 12.04 x64. I am working through some GRASS tutorials and am able to get a 3d raster to show up when I use the GUI. However, I cannot get the command line interface for the 3d raster to work. When I type
nviz ... or
wxnviz I get nothing. The manual only seems to clicking on the dropdown box on the displayed 2d image (generated from the command line) in order to show the 3d display. However, when I generate a 2d raster from the command line and then click on the dropdown box in the image window to make it 3d, I just get a blank screen.
So the functionality works in the gui but not from the command line.
Is there a way to generate a 3d display from the command line?
