# Convert Mesh to Color Voxel

Take `.ply` mesh format as input, convert it into voxel with color (rgba).

## Requirement

- c++11: for the package **tinyply**.

- numpy

## Usage

### Take the largest face inside the cube (voxel) to represent to color.

```

make MAX

./mesh2vox_max [input ply file] // output file is .dat

```

### Take weighted mean (by area size of faces) for the color of the voxel.

```

make MEAN

./mesh2vox_mean [input ply file] // output file is .dat

```

### Visualization

```

python3 read_buffer.py // generate .ply point cloud for visualization

```

Use tools like meshlab to open the `.ply` file.
