A quick google threw up an open source tool called MeshLab at
http://meshlab.sourceforge.net/. They have a wiki with some How-To's that
may get you started - Not quite a tutorial, but it does indicate how to
approach certain problems using available tools. Reading the feature list
should give you an idea of the wide range of things you'd need to read up on
if you wish to start develop your own methods and techniques for doing it.

Converting an arbitrary cloud of points into a mesh is a non-trivial problem. In
most cases, it just can't be automated. Even some of the simplest cases, all
points roughly limited to a mostly planar area, will give unexpected results,
giving you spikes and holes.
