stl-to-voxel

Turn STL files into voxels, images, and videos

Main Features

• Convert stl files into a voxel representation
• Output to (a series of) .pngs, .xyz, .svx
• Command line interface

How to run

Run in command line

pip install stl-to-voxel
stltovoxel input.stl output.png

Generating a higher resolution

stltovoxel input.stl output.png --resolution 200

Specifying voxel size

stltovoxel input.stl output.png --voxel-size .5

Multiple materials

stltovoxel input1.stl input2.stl output.png --colors "red,green"

Hex color values are also supported

stltovoxel input1.stl input2.stl output.png --colors "#FF0000,#00FF00"

Integrate into your code

import stltovoxel
stltovoxel.convert_file('input.stl', 'output.png')

Run for development

cd stl-to-voxel
python3 -m stltovoxel input.stl output.png
