Black Hole simulation project.

This is a fork of the original project with several enhancements.

I'm writing this as I'm beginning this project (hopefully I complete it ;D) here is what I plan to do:

1. Ray-tracing : add ray tracing to the gravity simulation to simulate gravitational lensing

2. Accretion disk : simulate accreciate disk using the ray tracing + the halos

3. Spacetime curvature : demonstrate visually the "trapdoor in spacetime" that is black holes using spacetime grid

4. [optional] try to make it run realtime ;D

I hope it works :/

Edit: After completion of project -

Thank you everyone for checking out the video, if you haven't it explains code in detail: https://www.youtube.com/watch?v=8-B6ryuBkCM

How the code works:

black_hole.cpp and geodesic.comp work together to run the simuation faster using GPU, essentially it sends over a UBO and geodesic.comp runs heavy calculations using that data.

should work with nessesary dependencies installed, however I have only run it on windows with my GPU so am not sure!

LMK if you would like an in-depth explanation of how the code works aswell :)

• Build System: Replaced cmake & vcpkg with xmake for a simpler and more unified build experience.
• Performance:
  • Enabled high-performance GPU selection by default to ensure better performance.
  • Added a display for FPS and camera information to monitor performance.
• Code Modernization: Refactored the entire project to use modern C++20 features.
• User Experience:
  • Initialized an appropriate camera view point for a better out-of-the-box experience.
  • Added more stars to the simulation for a richer visual.
• Code Quality: Performed code formatting and cleanup for better readability and maintenance.

0. Ensure you have a C++20-compatible compiler and xmake installed
1. Clone the repository: git clone https://github.com/chen-qingyu/black-hole.git
2. Into the newly cloned directory: cd ./black-hole
3. Build & Run the project: xmake run

Cross-platform, one-click operation, very convenient, and then you will see the beautiful black hole~
