- 4Hacker News·8/28/2026researchFast Mesh Volume Computation via the Divergence Theorem
The article describes a fast method for computing the volume of a simple, closed, triangulated 3D mesh using the divergence theorem. It reduces the problem to summing per-triangle surface integrals derived from vertex coordinates and a vector field with constant divergence. The approach is mathematically efficient and suitable for mesh processing workloads.

Eigendrum numerically computes the vibration modes and frequencies of drum-like shapes by solving a finite element eigenvalue problem on a triangular mesh. It lets users define shapes, strike points, and damping assumptions, and validates results against known exact spectra for circles and rectangles.
