Does anyone know, where I can get a datafile with lots of 3D-vertices? E.G. data of a medical model (bone, skull…) or car or something. The more 3D-vertices, the better.
Thanks dorbie! I wonder about the format .tar.
I expected data like x,y,z. Lets say float or something : 0.32, 0.55, 0.12 . If I look at this .tar file in a editor, I see hyroglyphs.
Hmm?
A .tar file is a compressed archive file common to Unix and workalike systems:

I’m sure you can find something to extract the contents of a tar file on windows.

From memory:
tar -xvf <filename>
use WinRAR to decompress tar files.(and i think WinZip/WinACE should do the job too)

Unpack the tar using either the real tar program or Winzip/Winrara/any of the usual unpackers.
The format these models are in is .ply, which is a little more complicated than a pure vertex list (it also has triangles 
), but they have code to load it linked on the site.
If you really just want point data, I’d recommend Julia4D . A nice little tool to generate 3D Mandelbrot sets at arbitrary resolution, and can output the model as a pointset.
Hope it helps
