The Polynomial That Fixed 30 Years of Cloth Simulation

# A Simple Math Fix Solves a 30-Year-Old Problem in Digital Clothing For three decades, animators and game developers have struggled with a persistent glitch when simulating how fabric moves and drapes in 3D environments—it keeps clipping awkwardly through other surfaces. A researcher discovered that swapping out one mathematical equation for another solves this annoying problem that's plagued the entire industry. The fix is surprisingly simple, which raises the question of why nobody caught it earlier.
