nviz - A GRASS Visualization Program
nviz is a GRASS module-in-progress which allows users
to realistically render multiple surfaces in a 3D space, optionally
using thematic coloring, draping GRASS vector files over the surfaces,
and displaying GRASS site files either draped on the surfaces or
as 3D point locations.
The current version, nviz 2.0 and above, has been completely ported
to use OpenGL for graphics.

Since each surface often consists of hundreds of thousands of
polygons, with render times of several seconds to a minute,
we represent the surfaces with wire meshes as a rough
approximation when a user is
