A fairly simple fractal renderer
- Preview window
- Multithreaded background PNG renderer
- Move and zoom around in the preview
- Render the currently visible area in the background in high quality
- Click anywhere to get the coordinates
- Fully configurable with hot reloading
To use the default configuration listed below, just start the program.
A custom configuration can be provided to override the defaults by providing the config file as the first argument to the program (this can be done by just drag-and-dropping the file onto the program).
It is not necessary to provide all options, the defaults will be used for any missing values.
The program supports config hot reloading, which means changes to the config file will be applied in real time when they are saved to disk.
