High performance, work in progress C/OpenGL rewrite of the infamous FractalViewer

Mandelbrot (WIP)

High performance, work in progress C and OpenGL rewrite of the infamous FractalViewer.

• Plain C/OpenGL implementation with GLFW and glad as the only dependencies
• Cross-platform
• Zero dynamic memory allocations

Definition

The mandelbrot set is defined in the complex plane as the complex numbers $c$ for which the function $f_c(z) = z^2 + c$ does not diverge to infinity when iterated starting at $z = 0$.

Progress

• GPU hello world (colored rectangle)
• First mandelbrot
• Explorable mandelbrot
• Custom color functions
• Julia set

Implementation details

The actual code for computing the mandelbrot set is defined in a GLSL fragment shader inside fractal.c.
