LanguageProject Introduction
Summary
Box2D is a popular open-source 2D physics engine widely used in game development to add realistic physical behaviors to objects.
Problem Solved
Developing physics interactions like collisions, gravity, friction, and joints from scratch is complex and time-consuming. Box2D provides a pre-built, optimized solution.
Core Features
Collision Detection and Response
Efficiently detects and resolves collisions between rigid bodies of various shapes.
Rigid Body Simulation
Simulates physics accurately using iterative methods, handling forces, gravity, and joints.
Joints and Constraints
Supports various joint types (revolute, prismatic, distance, etc.) to connect bodies.
Tech Stack
C++
