start here:

(ground based laser scanning is more difficult as nviz doesn't
like more than a few million vector points, but actual 3D point
cloud viz is possible [see the "Help with 3D" wiki page])

if you really want point cloud viz, see the PCL library:

GRASS focuses more on the analysis of LiDAR data (which is what
will give you answers instead of just the pretty pictures :)
