Particles

Crowd sensing road quality for optimal bicycle routing

Interactive Demo

Each particle has its own: #

• Color
• Size
• Mass
• Density
• Elasticity (Coefficient of Restitution)
• Surface Area
• Lifespan

Collisions were modelled for: #

• Walls and the roof(if On)
• With other particles
• All collisions took the radial distance from the particle center taking it’s individual Coefficient of Restitution and mass into account.

Two main forces were accounted for: #

• Gravity for various Planets, F = M*G
• Friction with various mediums (Drag), F = 0.5*C*p*A*V²

Controls: #

• Clicking places a “Launcher” Draging changes particles initial velocity
• SpaceBar, ‘M’ or Menu Button key shows/hides menu
• ‘P’ pauses the movement of the particles
  • Ctrl/CMD to toggle grabbing mode (or clicking “Grab Off/On” if on mobile)
  • Click and Hold on particle to grab it
  • Drag to move it and collide it with other particles
  • Release to throw

Sound: #

• Popping sound when particles die
• Bouncing sound when particles have a collision with volume proportional to magnitude of collision
