A simple GPU Julia sets and Mandelbrot set plotter

This program is a simple GPU, double-floating-point precision plotter for Julia sets and Mandlebrot sets. It is made with OpenGL compute-shaders and it is written in C.

Features

• Julia sets with live constant changing
• Mandlebrot set
• Live Panning and zooming
• Integer exponents
• Real exponents (Moivre's formula)
• Image exporting
• Uses -Wall and -Werror
• Works on both linux and windows

Todo (Not ordered)

• Multiple coloring methods
• Multiple coloring palettes
• Visualize the different values taken by the serie
• Buddhabrot fractal (probably another backend)
• Burning ship fractal
• Newton's fractals (another backend)
• Save locations
• Add some sort of configuration (Mostly to configure OpenGL workgroup sizes)

Dependencies

• OpenGL 3.3
• SDL2 for window and GL context
• GLEW for OpenGL
• Nuklear for UI
• Posix for file I/O
• tinydir.h (included) to scan directories
• stb_image.h (included) to read images
• stb_include.h (included) to use include directive in GLSL

Building

For Linux (and MacOSX but not tested):

Install SDL2 and glew through your package manager examble on Debian based systems:
# apt install libsdl2-dev libglew-dev
(Package name differ depending on distro)\

$ premake5 gmake2
$ make
$ ./romanesco

For Windows:

You must use Visual Studio / Visual C compiler : The necessary dependencies (include, libs and dlls) are included in the windows folder.

/!\ Current source generates alot of warnings on windows.

> premake5 vs2019 (Or the installed vs version)
> msbuild
The exe should the be built. Don't forget to include the SDL2.dll file next to the executable. The dll is included in windows\SDL2\lib\x64\SDL2.dll.
