A toy project intended to be featured on my personal website: https://isameru.pl
This is a web demo of N-body gravity simulation. Unlike its classical variant, this one incorporates elements of general relativty. The visualization itself shows the moving bodies - colorful stars - at their immediate positions relative to a static observer, as if light travels at infinite speed, without bending. However, the gravity attraction propagates at a finite speed, which is the maximum speed any simulation body can reach, governed by the Lorentz transformation. This is a mere approximation of the general theory of relativity formulated by Einstein, but subtly affects the movement patterns.
CMake is required to build the project in any configuration, as well as a modern C++ build toolchain.
Install CMake support addon for Visual Studio and open the project directory as CMake project.
The directory deps-win contains the necessary dependencies, including the binaries (.dll files).
After building the project with Visual Studio, you have to copy all .dll files to the location of the executable file.
sudo apt update
sudo apt install \
libsdl2-dev \
libsdl2-image-dev \
libsdl2-ttf-dev \
