A 2D physics engine in PHP — rigid bodies, PBD constraints, elastic collisions, bounciness. Runs with php -S and a browser.

Python package for structural analysis with trusses and beams

Computations for rigid body orientation network

Rigid body physics playground — spawn shapes, swing and throw them with real pivot joints, pin to walls, pymunk physics

Clean Python implementations of essential robotics math — deg↔rad, rotation matrices, rigid transforms, and transform chaining.

Colab/Jupyter UI wrapper for the HingeProt pipeline to predict protein hinges and rigid parts using elastic network models (GNM/ANM), with chain selection, CA-only support, and 3D visualization.
