DESCRIPTION¶
m.nviz.image allows users to realistically render multiple
surfaces (raster data) in a 3D space, optionally using thematic
coloring, draping 2D
vector data over the surfaces, displaying 3D
vector data in the space, and visualization of
volume data (3D raster
data) from the command line.
EXAMPLE¶
Render elevation map in a 3D space.
g.region rast=elevation
m.nviz.image elevation_map=elevation output=elev perspective=15
SEE ALSO¶
wxGUI 3D view mode
