Black-hole-simulation

Interstellar black-hole!(Gargantua) in C++ :)

Physics & Mathematics

• Schwarzschild radius: r_s = (2GM/c^2)
• Runge-Kutta4 to numerically estimate the trajectory of each light ray
• Gravitational lensing: Light bends due to curved spacetime near a massive object.
• Numerical integration: Simulating light-ray trajectories using numerical methods.
• GPU computing: GLSL compute shaders for simulation calculations.

Tech Stack

• C++
• OpenGL and GLSL
• GLFW, GLEW, GLM
• Git and GitHub

Project Files

• GargantuaH.cpp — Main simulation
• geodesic.comp — Compute shader
• grid.vert / grid.frag — Grid rendering shaders

Build and working

-The project is currently developed on Windows. Build requirements and instructions will be added as the build process is finalized.

-For the 3D sim:GargantuaH.cpp and geodesic.comp work together to run the simuation faster using GPU, essentially it sends over a UBO(Uniform Buffer Object) and geodesic.comp to run heavy calculations.

Future Work(IN PROGRESS)

• Improve gravitational lensing
• Accretion disk visualization
• Refine spacetime grid rendering
• Optimize GPU performance
