|OFF||Geometry description (one of) used by Geomview, basically a facet index list.|
The usual polygon soup, sometimes with a bit of meaningful incidence relations.
|teapot.off.gz||OFF||1976||3752||Utah teapot, triangulated mesh.|
|happy_vrip_res3.off.gz||OFF||32328||67240||Nice and large model. (happy_vrip_res3.txt)|
|happy_vrip_res4.off.gz||OFF||7108||15536||Smaller approximation of happy_vrip_res3.off? (happy_vrip_res4.txt)|
Except if otherwise mentioned, all objects are orientable and oriented 2-manifolds. Objects with border edges have an identifying comment. Objects can consist of multiple connected-components. Objects can have self-intersections, which will be mentioned in the comment (if known).
