QuarkPhysics is a 2D physics engine designed for games. Its goal is to provide a reasonable approach to simulate rigid bodies, soft bodies, and different physics models together.

Examples | API Documentation | wiki(coming soon)

Note: The project is in the development phase until v1.0.

• General Features

  • Primitive shape types (circle, polygon, rectangle...etc)
  • Physical properties (mass, area, restitution etc.)
  • The API is designed specifically for 2D video games.
  • Raycasting
  • Collision layer masks for advanced collision filtering
  • SAP for broadphase
  • Supports sleeping islands to improve CPU performance.
  • Flexible and advanced event system.
  • It uses pixels directly as a unit without any abstractions.
  • Unlimited shape-mesh support for bodies.
  • Simple and consistent API
  • QMesh Editor app for editing mesh features of the bodies (coming soon)

• Rigid bodies

  • Joints to connect bodies
  • Reasonable stability for stacked objects.
  • Kinematic bodies for creating controllable physics objects.
  • Area bodies for detecting and reporting collisions.

• Soft Bodies

  • Springs to connect particles.
  • Mass-spring model.
  • Area-volume preserving model.
  • Shape matching features.
  • Self collisions.
  • PBD dynamics.
  • Internal springs and internal particles for adding more complexity to soft body simulations.
  • Customizable constraints for adding more control to simulations.
  • Advanced particle methods.

You need to install SFML and CMake on your system before.

Download project, enter the main folder and call this;

    ./build.sh -r

Another way is that compiling the project directly via gcc if you're on linux call;

    ./run_linux_fast.sh -r

Copy the "QuarkPhysics" named subfolder in the main folder to your project and use it.

• nlohmann's json for the json parsing. (Importing meshes via *.qmesh files)
• SFML library for window,input,opengl.
