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:

``sh
$ npm i voxelizer.c
`

And then include voxelizer.h as follows:

`c
// main.c
#define VOXELIZER_IMPLEMENTATION
#include

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

Finally, compile while adding the path node_modules/voxelizer.c to your compiler's include paths.

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

You may also use a simpler approach with the cpoach tool, which automatically adds the necessary include paths of all the installed dependencies for your project.

`bash
$ cpoach clang main.c # or, use gcc
$ cpoach gcc main.c
`




Usage

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

`c
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);
