Vertex animation / point cache files

Has anyone used pointcache files to get vertex animation into vvvv?

I think it’s an Autodesk thing

should be easy to write a shader to modify the vertex positions but I don’t know how to parse the files.

You can download an example point cache here if you want to have a go, along with a python script that demonstrates how to read them https://www.dropbox.com/s/xbqbb45xek7hfr5/vertex%20animation.zip
