Animation Physics & Simulation

Springs, cloth, particles, curves, and ragdolls — the physics engines that make digital worlds feel real, from game engines to visual effects pipelines.

Every bouncing character, flowing cape, and flickering flame in a video game or film is powered by real physics — simplified and optimized for real-time performance. Animation physics bridges Newtonian mechanics and computer graphics, using numerical integration, constraint solvers, and particle systems to create convincing motion.

These simulations let you manipulate springs, drape cloth over obstacles, spawn fire and smoke particles, shape Bezier animation curves, and pose ragdoll skeletons. Tweak parameters and watch the physics respond instantly — the same feedback loop used by engineers at Pixar, Epic, and Unity.

5 interactive simulations

Bezier Curve Animation Paths Simulator

Design and visualize cubic Bezier curves used for animation easing, motion paths, and vector graphics — drag control points and see De Casteljau's algorithm in action

simulator

Cloth Simulation With Constraints Simulator

Drape a particle-based cloth mesh over obstacles using distance constraints and Verlet integration — the technique behind capes, flags, and fabric in real-time graphics

simulator

Particle System Effects Simulator

Spawn, animate, and blend thousands of particles to create fire, smoke, sparks, and explosions — the visual effects system powering every game engine

simulator

Ragdoll Physics Joint Constraints Simulator

Build and simulate a ragdoll skeleton with angular joint constraints — the physics system that makes characters tumble, collapse, and react to impacts in games

Spring Dynamics & Verlet Integration Simulator

Simulate spring-mass systems using Verlet integration — the stable numerical method behind hair, jelly, and soft-body physics in games and film
