# C++ Simple physics engine

Implements a simple physics engine in C++ based on [Verlet integration](https://en.wikipedia.org/wiki/Verlet_integration) and [Verlet constraints](https://en.wikipedia.org/wiki/Verlet_integration#Verlet_constraints).

## About

You can check the WEB version [here](https://leandrosq.github.io/cpp-physics-sandbox/). It is a port using WASM generated by Emscripten using WebGL on the browser.

* Restricted only to circles

* Supports gravity

* Supports collisions

  * Implements a Quadtree for collision detection

* Supports constraints

  * Implements both a circle and a rectangle world constraint

* Supports user interaction

  * Dragging

  * Spawning

  * Explode

## Controls

### Desktop

>  `Left click` to spawn circles

>  `Right click` to drag circles

>  `Middle click` to explode circles

>  `Space bar` to flip the Gravity vector

>  `Z` to toggle Gravity ON/OFF

>  `Up arrow` to increase the Gravity force

>  `Down arrow` to decrease the Gravity force

>  `Left arrow` to decrease the Gravity angle

>  `Right arrow` to increase the Gravity angle

>  `ESC` to exit



    Other controls included on the GUI can be used with the mouse as demonstrated below.
