High resolution vertex data models can be found @ http://www.cyberware.com/products/scanners/pxSamples.html
Other scan samples @ http://graphics.stanford.edu/data/3Dscanrep/
For vertex point extraction i used a program from Kárpáti Zoltán (http://web.axelero.hu/karpo/) 
and slightly modified the obtained txt file for my own purposes.
We need only the x, y and z coordinate, so other aditional information can be deleted.
