Function marching_cubes 

pub fn marching_cubes(
    field: &[f32],
    isoval: f32,
    nx: u32,
    ny: u32,
    nz: u32,
) -> McmMesh

Extracts the isosurface from a 3D scalar field using marching cubes.

Arguments

• field - Scalar field values in C-contiguous order: the value for grid point (ix, iy, iz) is stored at index (ix * ny + iy) * nz + iz.
• isoval - The isovalue defining the surface (surface is where field == isoval).
• nx, ny, nz - Grid dimensions (number of nodes in each direction).

Returns

A mesh with vertices in grid-index space (integer coordinates interpolated along edges). The caller must transform vertices to world space using grid spacing and origin.

Panics

Panics if field.len() != nx * ny * nz or if any dimension is less than 2.
