Real-Time Cloth Simulation in Three.js
Oct 15, 25Real-Time Cloth Simulation with Cubic Barrier Forces
This demo implements a real-time cloth simulation using mass-spring dynamics with cubic barrier forces for collision handling. The cloth is modeled as a grid of particles connected by springs, with contact forces that prevent penetration through obstacles.
Key Features
- Mass-Spring System: Cloth modeled as particles connected by structural, shear, and bend springs
- Cubic Barrier Forces: Smooth contact forces that prevent cloth from penetrating obstacles
- Interactive Controls: Drag cloth vertices with mouse, toggle gravity and wireframe modes
- Real-time Performance: Optimized physics simulation running at 60 FPS
Physics Implementation
The simulation uses:
- Verlet Integration: For stable particle motion
- Spring Forces: Hooke’s law for cloth elasticity
- Barrier Method: Cubic penalty forces for contacts
- Damping: To prevent excessive oscillation
