This is a minimal Python implementation to demonstrate how to use line quadrics in mesh simplification, based on the paper "Controlling Quadric Error Simplification with Line Quadrics" by Hsueh-Ti Derek Liu, Mehdi Rahimzadeh, and Victor Zordan, presented at SGP 2025.
To run the demo, one can simply run the example script with
python main.py
to simplify the input mesh down to a lower resolution.
