format is popular with 3D printers, which is how I became familiar with it.
This format is simple to implement and easy for a computer to read, but if you have a model in that
format that you need to manipulate, you won't have a good time. In order to actually do things like
change the shape of the model, it needs to be converted into a CAD program's native representation
of a "solid body", which is pretty much what it sounds like: a shape made of a finite volume of
"stuff", instead of an infinitesimally thin shell enclosing an empty volume, which is what the mesh

meaning, no missing faces (triangles), and with a clearly-defined interior and exterior (all

But so far, I had nothing at all. Time to get some data and see if I can turn it into a model.
