Distortion Renderer for cylinders, half-spheres and arbitrary straight-line shapes.

Install python environment:

• conda create -n "distortion" python=3.10
• pip install -r ./requirements.txt

Activate conda environment through conda activate distortion

Download blender 3.2 from https://download.blender.org/release/Blender3.2/ and unzip into ./blender;

Remove blender's bundled python folder at ./blender/blender-3.2.2-windows.x64/3.2/python

• or copy paste conda's python env folder (e.g. envs/distortion) into ./3.2 and rename it to python;

Remove the freestyle folder at <conda_path>/envs/distortion/Lib/site-packages/freestyle to make blender fallback to its own freestyle module.
