Aerolite Physics Engine is a comprehensive, efficient 2D physics library with planned extensions for 3D simulations. Tailored for game development and graphical simulations, it offers a robust platform for realistic physics behavior in a variety of environments.
- 2D and Planned 3D Support: Robust support for 2D physics and a roadmap for 3D simulation capabilities.
- AeroWorld2D: A dedicated 2D world manager for handling physics simulations.
- Collision Detection and Response: Advanced algorithms for detecting and responding to collisions between various shapes (circles, polygons, boxes) using methods like AABB and SAT (Separating Axis Theorem).
- Rigid Body Dynamics: Simulates realistic rigid body dynamics, including rotation and translation.
- Impulse Resolution: Implements impulse resolution for accurate collision responses.
- Force Generators: Flexible force generators to simulate gravity, drag, springs, and more.
- Constraint Systems: Implements constraints for realistic joint and articulated structure simulation.
- Particle Systems: Efficient particle system for simulating large numbers of interacting objects.
- Material Properties: Customize friction and restitution for different materials for varied interaction effects.
- Numerical Integration: Utilizes Euler and Runge-Kutta integration methods for precise motion calculation.
- Broad and Narrow Phase Collision Detection: Efficiently detects collisions using AABB for broad phase and SAT for narrow phase.
- Impulse-Based Dynamics: Applies realistic impulses to bodies for authentic movement.
- Constraint Solving: Simulates complex joint behavior with constraints.
- Particle Dynamics: Manages large numbers of particles effectively for simulations like smoke or liquid.
- Creating and Configuring a 2D Body
// Creating a box body
auto box = std::make_unique<Aerolite::Body2D>(new BoxShape(50, 50), 100, 100, 10.0);
box->restitution = 0.8;
- Creating and Adding bodies to the world
auto box = std::make_unique<Aerolite::Body2D>(new BoxShape(50, 50), 100, 100, 10.0);
world->AddBody2D(std::move(box));
-
Running the simulation
world->Update(deltaTime); -
Applying force
// Applying a force to a body
Vec2 force(10.0, 0.0);
box->ApplyForce(force);
- Collision Detection & Response
// Assuming bodyA and bodyB are already created and initialized
Aerolite::Contact2D contact;
if (CollisionDetection2D::IsColliding(*bodyA, *bodyB, contact)) {
contact.ResolveCollision();
}
