Partical Collision simulation - more info: https://ciancode.com/particles

Live 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 = 0.5CpAV2

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
  • Click and Hold on particle to grab it
  • Release to throw

Sound:

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