Extracted from file 1mesh_ 56_N_7_Ffl_0_V1.pfb (OpenGL Performer format) using my PFB converter: https://github.com/jumpjack/VST-converter
Extracted raw point cloud from file, then (badly) reconstructed surface using meshlab. (PFB contains also faces and textures, but I don't know how to extract them).
