# MagicaVoxel File Writer
Rust Version available here : [MagicaVoxel File Writer for Rust](https://github.com/aiekick/MagicaVoxel_File_Writer_for_Rust)
vox.hm is the file format descriptor for HexaMonkey :
- original topic about it : https://github.com/ephtracy/voxel-model/issues/19
- HexaMonkey tool : http://hexamonkey.com/
## App
the main.cpp file show you how to generate a quick file :
With this simple code
```cpp
#include "VoxWriter.h"
int main()
{
const int32_t SIZE = 189;
const int32_t OFFSET = SIZE;
const float Z_SCALE = 1.0f;
const int32_t FRAMES = 30;
const float len_ratio = 1.0f / (SIZE * SIZE);
vox::VoxWriter vox;
vox.StartTimeLogging();
float time = 0.0f;
for (int32_t k = 0; k < FRAMES; ++k) {
vox.SetKeyFrame(k);
for (int32_t i = -SIZE; i < SIZE; ++i) {
for (int32_t j = -SIZE; j < SIZE; ++j) {
float len = (i * i + j * j) * len_ratio;
int32_t pz = (int32_t)((std::sin(len * 10.0 + time) * 0.5 + 0.5) * (std::abs(50.0f - 25.0f * len)) * Z_SCALE);
int32_t cube_color = (int32_t)(len * 100.0) % 255 + 1;
vox.AddVoxel(i + OFFSET, j + OFFSET, pz, cube_color); // magicavoxel use the z as up axis
}
}
time += 0.5f;
}
vox.StopTimeLogging();
vox.SaveToFile("output_voxwriter.vox");
vox.PrintStats();
}
```
you can generate that (previewed in [Magicavoxel](https://ephtracy.github.io/)
possible console print ( vox.PrintStats() ) :
