I am working with the surface meshes in the dataset.

For the calculations I want to perform (e.g. volume of the object) the winding order of the vertices is important.

The standard convention is to use the CCW ordering of the vertices when viewing the object from the outside.

Are the mesh files provided with the CCW winding order?

I am using the pymeshlab library to load the surface mesh and calculate the volume, which turns out to be negative. I am not sure if pymeshlab follows this convention either.

Any insights would be appreciated.
