Hilariously fast volume computation with the divergence theorem (2018)

alyssarosenzweig.ca 6 min read

The following presents a fast algorithm for volume computation of a simple, closed, triangulated 3D mesh. This assumption is a consequence of the divergence theorem. Further extensions may generalise to other meshes as well, although that is presently out of scope.
