Hi,
Sean has left the following comment at Implement a volume function for
triangle meshes (BOT)
http://www.google-melange.com/gci/task/view/google/gci2013/4814313936125952:
volume or surface area?
Johannes,
Upon quick inspection, it looks like you calculate total surface area, not
volume? Or is this based on the tetrahedron method where you use the
surface normal to add/subtract tetrahedron areas?
I kind of see the latter in your calculations, but that implies we'll need
some protections in place for non-closed meshes. Basically, it just amounts
to adding a check that tests whether a mesh is in volume mode (closed) or
surface mode with a thickness.
