Slice STL files to black-and-white png images that are used in stereolithographic 3D printing.

To use app_pyopengl.py, make sure glfw is installed. Mac users can use brew to install it.

Steps:

• Install Python Anaconda (Python 3.7.3)
• Create and activate virtual environment
• Install dependencies

Follow the installation instructions found here. Be sure to get Python 3.7.3. Be sure to check the box to add it to your path.

In a shell of your choice:

# install virtualenv
pip install virtualenv
# create new virtual environment named 'env'
python -m virtualenv env
# activate the virtual environment
.\env\Scripts\activate
# install all dependencies
pip install -r .\req.txt

When you want to use the slicer, you will have to activate the virtual environment again with

# activate virtual environment
.\env\Scripts\activate
# run slicer with the GUI
python slicer_gui.py
