Brake Pedal Fracture in 3D: A Visual Explainer

A roughly five-minute 3D engineering explainer built from scratch: recreating a brake pedal assembly in three.js, computing a live stress heat map in a shader, and growing a crack with every pedal press until it snaps — with bilingual subtitles and ElevenLabs voiceover, and zero stock assets. Suited to engineering-principle breakdowns, automotive safety education, and long-form knowledge content.
