Boids Simulation

Boids simulation system, implementing spatial partitioning and multithreading for trying to reach 60 FPS with 1000 boids.

Overview

• Spawn customizable boid swarms with adjustable parameters (count, radius, speed)
• Craig Reynolds three behaviors: Separation, Alignment, and Cohesion
• Field of View system - boids only react to neighbors within their view angle
• Object avoidance using golden ratio sphere distribution for ray casting
• Spatial grid partitioning (Chunks system)
• Multithreaded calculations using ParallelFor for parallel behavior processing

Debug Tools

• Spatial grid visualization with cell boundaries

Configuration Parameters

Spawner Settings:

• NumberOfBoids: Boid count to spawn
• SpawnRadius: Initial spawn area radius
• BoidSpeed: Movement speed

Behavior Settings:

• MaxSeparationDistance / SeparationStrength
• MaxAlignmentDistance / AlignmentStrength
• MaxCohesionDistance / CohesionStrength
• ViewAngle: Field of view in degrees (0-180)

Object Avoidance:

• AvoidanceDistance: Ray cast distance
• AvoidanceRayCount: Number of detection rays
• AvoidanceStrength: Avoidance force multiplier

Spatial Partitioning:

• GridCellSize: Size of each grid cell
• WorldExtent: Total grid coverage area

In startup scene, there are 500 boids reaching 60 fps simulation.

Unfortunately, spawn 1000 boids affect performance and simulation reach env. 40 fps.
