Realtime Marching cubes for Wolfram Language

A mediocre implementation in pure C and LibraryLink, aimed to be crossplatform

Alpha version

Interface

There is single function to calculate vertices and normals for the given 3D scalar field

{vertices, normals} = CMarchingCubes[scalar3D_List, isoSurface_Real, opts___]

where following options are supported

"CalculateNormals" uses more advanced procedure to calculate normals per vertices as well. By the default is True. If False it will return None for normals.

native = ImageMesh[Image3D[data3D], Method -> "MarchingCubes"] // AbsoluteTiming;

cversion = CMarchingCubes[data3D, 0.5] // AbsoluteTiming;

the results for 15x15x50 array on Mac Air M1 are following

{0.2767, ...} (* native *)
{0.0033, ...} (* cversion *)

Current only for Wolfram Kernel > 13.3
