You're totally welcome. If you have any more questions, please feel free to ask.
Above, by the fourth link, I meant to mention Meshlab's 'Import Photosynth data' filter.
(Access via 'Filters' > 'Create New Mesh Layer' > 'Import Photosynth data')
(You'll also want to set 'Render Mode' to 'Points', set 'Color' to 'Per Vertex', and set 'Lighting' to 'Off')
Also note that this is only if you want to use Meshlab's built in Photosynth import option and this is not necessary if you are saving the point clouds with one of the other utilities that I listed and only want to view those with Meshlab.
