# Real-time Black Hole Rendering in OpenGL

![Screenshot](docs/blackhole-screenrecord.gif)

## Prerequisite

- [cmake](https://cmake.org/)

- [conan](https://conan.io/) package manager [^1][^2]

[^1]: You might need to configure [$HOME/.conan/conan.conf](https://docs.conan.io/en/latest/reference/config_files/conan.conf.html) and Conan [profiles](https://docs.conan.io/en/latest/reference/profiles.html) if the `default profile` is not generated due to different build environments on your distribution.

[^2]: Conan 1.xx instead of conan 2.xx or higher is suggested in order to avoid unnecessary problems.

## Build the code

```bash

# Configure the project and generate a native build system.

cmake -DCMAKE_BUILD_TYPE=Release -S . -B build

# Compile / build the project.

cmake --build build

```
