Bevy Newton - Newtonian Physics for Bevy

A feature-rich Newtonian physics engine natively integrated with the Bevy game engine.

Features

• 🚀 Rigid Body Dynamics
  • Linear & angular velocity integration
  • Mass properties and inertia tensors
  • Force/torque accumulation
• 🔥 Collision Detection
  • Sphere, Box, Capsule, and Convex Hull primitives
  • Broad-phase spatial partitioning
  • Narrow-phase SAT (Separating Axis Theorem)
• ⚡ Collision Resolution
  • Impulse-based contact resolution
  • Restitution (bounciness) and friction
  • Collision events and queries
• 🧠 Advanced Features
  • Continuous collision detection
  • Raycasting and shape queries
  • Joint constraints (ball, hinge, prismatic)
  • Force fields and area effects
