Galaxy is a simulator of colliding galaxies using the N-body model. Implements simple bruteforce and Barnes-Hut alogrithms. It was written back in my student years, around 2012. Later it was rewritten to use my own little private game engine and to do computations in parallel. Also an attempt to move computations to GPU was made, but OpenGL is not suitable enough to implement some crucial part of hierarchical algorithm. So GPU implementation is broken now until Vulkan support is integrated into my engine.
