Module marching_cubes 

Marching cubes isosurface extraction from 3D scalar fields.

Converts a scalar field (orbital ψ or density ρ) into a triangle mesh at a specified isovalue. Reference: Lorensen & Cline, SIGGRAPH 1987.

GPU path: dispatches a WGSL compute shader that processes each voxel independently, then reads back the generated triangle vertices. CPU path: triple-nested loop (always available as fallback).

Structs

McOutput
