Boids 🕊

boids is a flocking simulator written in Rust, using the Nannou framework.

---

Features 🐤

• Modeled after Craig Reynold's Boids algorithm, follows three simple steering behaviours
  • Alignment - Steer towards the average direction of local flockmates.
  • Cohesion - Steer towards direction of average position of nearby flockmates.
  • Separation- Steer away from flockmates that are too close to avoid crowding.
• 🐣 Adjustable number of boids, from 100-1000.
• 🦅 Predator boid that "hunts" the prey boids.
• 🖼️ Themes!
