SpaceSim

A high-performance gravitational physics simulator built with C++ and OpenGL.

Features

• Barnes-Hut Algorithm: Optimized $O(N \log N)$ force calculation using a Quadtree.
• Physics Integrators: Supports Euler, Verlet, and RK4 integration.
• Real-time UI: Uses Dear ImGui for live parameter tuning.
• Efficient Rendering: OpenGL instanced rendering for thousands of particles.

Build Requirements

• C++17 Compiler
• CMake
• OpenGL & GLFW
• Dear ImGui (included as submodule)
