Boidsy is a real-time 2D and 3D boid (flocking) simulation powered by Bevy and Rust.
It showcases emergent behavior through simple local rules such as alignment, cohesion, and separation, rendered efficiently using a modern ECS-based engine.
This project was developed as part of the "Projet 3D" teaching unit at the University of Montpellier, during the Master 2 IMAGINE program.
- 🚀 Real-time 2D and 3D boid simulations
- 🧠 Emergent flocking behavior (alignment, cohesion, separation)
- 🎛️ Extensive control over scene parameters via integrated UI
- 🎮 Smooth camera controls and scene transitions
- ⚡ Good performance, leveraging Bevy ECS and rendering systems
- 🌊 Underwater scene using marching cubes algorithm for terrain generation
- Bevy - Game engine (v0.12)
- bevy_egui - UI integration (v0.24)
- bevy_spatial - k-d tree (v0.7)
- noise - Perlin noise generation
- Rust 1.70.x – 1.75.x (required for Bevy 0.12.0)
- Cargo (comes bundled with Rust)
Install Rust easily with rustup.rs if you haven't already!
