Efficient Volume Calculation for 3D Meshes Using the Divergence Theorem

#3d mesh #divergence theorem #volume computation

This article presents an efficient algorithm for computing the volume of a 3D mesh using the divergence theorem, converting the volume integral into a surface integral over triangles. The method achieves O(n) time complexity with 11n floating-point operations, enabling fast volume calculations even on low-power hardware.
