# MarchingCubes

Julia port of [Efficient Implementation of Marching Cubes' Cases with Topological Guarantees](https://www.tandfonline.com/doi/abs/10.1080/10867651.2003.10487582).

Public article available [here](http://thomas.lewiner.org/pdfs/marching_cubes_jgt.pdf).

# Implementation

Adapted to `Julia` (`1` based indexing) from the original [c++ implementation](http://thomas.lewiner.org/srcs/marching_cubes_jgt.zip) (`0` based indexing).

# Tiny benchmark - visualization with ParaView

```bash
$ g++ -O3 ply.c main.cpp MarchingCubes.cpp
$ ./a.out
Marching Cubes ran in 0.007834 secs.
$ julia --check-bounds=no
julia> using BenchmarkTools, MarchingCubes
julia> mc = MarchingCubes.scenario();
julia> @btime march($mc)
  7.865 ms (0 allocations: 0 bytes)
julia> @btime march_legacy($mc)
  9.268 ms (0 allocations: 0 bytes)
julia> using PlyIO
julia> MarchingCubes.output(PlyIO, mc)  # writes "test.ply" (can be opened in a viewer, e.g. ParaView)
```

Test scenario output:

# MWE demonstrating visualization with MeshViz.jl

```julia
using MarchingCubes
using GLMakie
using MeshViz
using Meshes

mc = MarchingCubes.scenario()
march(mc)
msh = MarchingCubes.makemesh(Meshes, mc)
display(viz(msh))
```

# MWE demonstrating visualization with GeometryBasics.jl and Makie.jl

```julia
using GeometryBasics
using MarchingCubes
using GLMakie

mc = MarchingCubes.scenario()
march(mc)
msh = MarchingCubes.makemesh(GeometryBasics, mc)

fap = mesh(msh; color = :gray)
display(fap)
```
