粒子沙画
彩色细沙从上方倾泻而下、沿斜坡滑动堆积成丘，拖动即可在任意处倾倒彩沙。
About Sand Art
Sand Art is an interactive fluids & physics effect. Grains of colored sand pour from above, sliding down slopes and piling into dunes; drag to pour sand anywhere. Manipulate physical parameters and watch the simulation respond instantly. The physics engine computes forces, velocities, and interactions in real-time for realistic behavior. This effect runs directly in your browser using HTML5 Canvas, with no downloads or plugins required.
How to Interact
Move your mouse to disturb the fluid or interact with physical objects. Click and drag to create ripples, push elements, or redirect flow. Adjust parameters in real-time to change simulation behavior.
Technical Details
Powered by real-time physics simulation on HTML5 Canvas. Uses numerical integration methods for fluid dynamics, Verlet integration for cloth, or per-pixel computation for fire effects. All computation happens client-side.
Use Cases
Great for studying physics simulations, creating ambient backgrounds, generating satisfying visual content for social sharing, or as reference for game development physics implementation.
