This page provides a links to a range of tutorials. If you are new to SPDLib it is suggested that you first follow the basic tutorials and from then on pick and choose the move advanced tutorials based on your needs.
When visualisation is referred to within the tutorials one of two things may be meant. If you the output you are visualising is a raster then a viewer such as ENVI or Erdas Imagine is recommended although free alternatives such as QGIS are also OK. When visualising the 3D LiDAR data then the SPD Points Viewer is to be used. If the SPD points viewer is installed centrally then from the command line just run the command SPDPointsViewer (case sensitive) otherwise you will need to run the application from it's local installation directory. If you are on a Mac then there should be an SPDPointsViewer application within your applications directory. If you have a DTM of the area which coincides with the point data (such as one derived within SPD) then this can be viewed alongside the point data by selecting File > Open DEM (note that any GDAL supported raster format can be opened). When displaying a surface in 3D lighting is required which can result in a poor representation of the point data, if this is the case try either turning off the point data or turning off the lighting and using a wireframe for the surface.
