Hey,
My only concern with the ply reader is that it be able to support the
Stanford sculptures --- in particular the 1mm David head with per-vertex
color data. If you haven't seen these datasets, take a look at
/usr/sci/data/Geometry/Stanford_Sculptures
I imagine you already know this -- but just in case -- there is some code
available for reading ply files at
http://www.cc.gatech.edu/projects/large_models/ply.html
