(D1) Particle on a Surface
A discussion about constrained particle motion. We derive the equations of motion of a particle on a curve, torus, sphere, and surface of revolution.

Analog Input
A comprehensive treatment of analog input. We explore signal filtering, deadzones, sensitivity curves, and circle to square mappings, and we discuss how to expose such mappings in an in-game menu.
