Rocket simulation

Code that simulates rigid bodies.
Rendering is done using OpenGL with Dear ImGui.

Units: SI

The project uses CMake and requires C++23 or later.

Only tested building on Windows 10 with MSVC and Clang so results on other platforms may vary.

Clone the repository and submodules
```
git clone --recursive https://github.com/Lokestrom/rocketSim-code
```
Forgot to use --recursive just run: git submodule update --init --recursive

Build using CMake (version 4.1 or later)

cd rocketSim-code
cmake -S . -B build # create build files
cmake --build build --config <configuration> # Debug or Release

Run the program

build/<configuration>/app # Debug or Release

Click "new simulation" then "create" in the popup (ignore the text input not in use currently).
Now 3 windows will open (they may be small, just expand them as needed).
In the Test Adder window, you can:
- Add an example with a rotating cuboid and a small sphere orbiting, or
- add your own rigid body.

The simulation uses Newton's Law of Universal Gravitation, integrated using fourth-order Runge–Kutta (RK4).

NOTE:

When adding rigid bodies it takes some time before they appear. This is do to the simulation running in a separate thread. I have plans on a rework of the cache system to make it more responsive and enable saving/loading of simulations.
If you want more responsive adding of bodies you can go to the Simulation/Simulation/RenderingCache.hpp file and change the std::atomic<unsigned int> _maxFrames at the end of the class and file to 1 (currently set to 100). This can cause some stuttering in the rendering and a performance loss in the simulation.
