Apparently back in 2008 I tried to write a fractal explorer using nothing but C99, OpenGL and pthreads. It depends on the usual GL/GLU/GLUT stack, plus libGD.
Build it with make
, run it with ./fractal
. The arrow keys pan the
image, the plus and minus keys zoom in and out. Zooming in to 200% causes a
new image to be generated.
I never finished it, and I haven't touched the code in a long time - how it actually works is an exercise for the reader.
