A 2D impulse-based rigidbody simulator

2D Impulse Based Physics Engine

What does this do?

This is basically a 2D rigidbody simulator.
You can spawn circles and convex polygons and let them collide!
In addition, you can dynamically create custom polygon objects
or create a spring that connectes two arbitrary objects using right-click.

'impulse based'?

Collisions are handled by finding an appropriate
impulse vector which satisfies Newton's law of restitution.

How to build

Step 1) clone vcpkg

git clone https://github.com/microsoft/vcpkg
./vcpkg/bootstrap-vcpkg.bat

Step 2) cmake

cmake -S . -B build -DCMAKE_TOOLCHAIN_FILE="vcpkg/scripts/buildsystems/vcpkg.cmake"
cmake --build build

You can also use CMake extension on VSCode to configure and build.
