A high-performance, visually interactive 2D boids (flocking) simulation written in modern C++ using OpenGL, GLFW, and ImGui. Features GPU instancing, dynamic behavior control, and intuitive mouse interaction.

Speed-Based Coloring	Friend Influence Visualization

• 🚀 Instanced rendering of hundreds/thousands of boids using a single draw call
• ⚙️ Real-time control over:
  • Separation, alignment, cohesion weights
  • Speed limit
  • Edge behavior (wrap/bounce)
  • Color: speed-based or friend-averaged
• 🖱️ Mouse interaction:
  • Left click — Attract boids
  • Right click — Repel boids
  • Middle click — Spawn 100 boids at mouse location
• 🎮 UI built with ImGui (custom sci-fi styled)
• 📐 Dynamic viewport resizing and zooming support

Each boid:

• Aligns with neighbors' direction
• Moves toward average neighbor position (cohesion)
• Avoids crowding (separation)
• Interacts with mouse position (attraction/repulsion)
• Can bounce or wrap off screen edges
• Can be colorized based on velocity or group blending
