Mesh voxelizer

Header only mesh voxelizer in ANSI C

About

Converts meshes and performs triangle-cube intersection to output a voxelized mesh. By Karim Naaji.

Installation

Run:

$ npm i voxelizer.c

And then include voxelizer.h as follows:

// main.c
#define VOXELIZER_IMPLEMENTATION
#include "node_modules/voxelizer.c/voxelizer.h"

int main() { /* ... */ }

And then compile with clang or gcc as usual.

$ clang main.c  # or, use gcc
$ gcc   main.c

You may also use a simpler approach:

// main.c
#define VOXELIZER_IMPLEMENTATION
#include <voxelizer.h>

int main() { /* ... */ }

If you add the path node_modules/voxelizer.c to your compiler's include paths.

$ clang -I./node_modules/voxelizer.c main.c  # or, use gcc
$ gcc   -I./node_modules/voxelizer.c main.c

Usage

To generate a voxelized mesh, create an instance of vx_mesh_t and initialize its vertices and indices like this:

vx_mesh_t* mesh;
vx_mesh_t* result;

mesh = vx_mesh_alloc(nvertices, nindices);

// Add vertices and indices from the original mesh you want to voxelize
// [...]

// Precision factor to reduce "holes" artifact
float precision = 0.01;

// Run voxelization
result = vx_voxelize(mesh, 0.025, 0.025, 0.025, precision);

vx_mesh_free(result);
vx_mesh_free(mesh);
