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.

Benchmark

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 *)

Platforms supported
