## 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.

```sh
g.region raster=elevation
m.nviz.image elevation_map=elevation output=elev perspective=15
```
