## Description
A very simple SDL3 Julia Set Viewer.
It uses the function defined as $f(z) = z^{2} + c, \{z, c\} \in \mathbb{C}$
Everything is computed on CPU, mono-threaded... really not something worth looking at for performance :-)

## Usage
The following keyboard keys can be used to explore the Julia Set being rendered:
- Page Up: zoom out
- Page Down: zoom in
- Up: move up
- Down: move down
- Right: move right
- Left: move left
- i: decrease the imaginary part of the julia c constant
- Shift+i: increase the imaginary part of the julia c constant
- r: decrease the real part of the julia c constant
- Shift+r: increase the real part of the julia c constant
- p: print the current Julia set constant and rendering position on console
## How to build
### Pre-requisites
- CMake >= 3.23
- A C++11 compiler toolchain
- SDL3 library
If your system doesn't include `SDL3`, the repository contains everything required
to use the SDL3 source as a GIT submodule.
```bash
git submodule update --init
```
### Configuration and build
Then follow the typical `CMake` based project workflow.
```bash
cmake -B build -S . -G "Ninja Multi-Config"
cmake --build build --config Release --target sdl3-julia-set-viewer
```
## Working on the code
You're free to work the way you like...
However, if you never made your mind about what you consider the best
editor/IDE, a very minimalistic `.vscode` subdirectory is included to
facilitate the editing/debugging of this code with `VSCode`.
The following `VSCode` extensions might help you edit/build/debug this project:
- Microsoft C/C++ (ms-vscode.cpptools)
- CMake-Tools (ms-vscode.cmake-tools)
- CMake Language Support (josetr.cmake-language-support-vscode)
- markdownlint (davidanson.vscode-markdownlint)
`.clang-format` files are provided for automatic indentation. This requires
a `clang-format` tool >= 16.0.
