Pendula is a real-time motion tracking and physics visualization tool.

It captures your raw 2D mouse or stylus movements and automatically determines your swing's primary angle using Principal Component Analysis (PCA).

Simultaneously, a live machine-learning optimization algorithm runs in the background to fit your imperfect human motion to the ideal mathematical equation for Damped Simple Harmonic Motion:

How to interpret the tracker:

• Blue Trace: The raw input data from your mouse/stylus.
• Orange Trace: The Live Predictive model (calculating rapidly during your swing).
• Red Trace: The Final Post-Processed fit (calculated using rigorous simulated annealing once the pen stops).

Try placing your drawing tablet pen on its side and giving it a gentle nudge. You will see its natural decay perfectly match the math!
