smooth mandelbrot

The Mandelbrot set using the Escape Time algorithm, and smooth coloring. 1k iterations is ~1.3 seconds on a 800x600 window on a chromebook. I stole the smooth coloring algorithm from https://en.wikipedia.org/wiki/Plotting_algorithms_for_the_Mandelbrot_set. uses GL/glut.h= g++ mandel.cpp -o mandel -lGL -lGLU -lglut -Ofast to compile on linux. requires freeglut3.

multithreading for some reason only slows stuff down (using omp.h), so not doing that.

Controls:

Drag to move.

Q/E to zoom in/out.

-/= to change the maximum amount of iterations.

1 for Mandelbrot set.

2 for Burning Ship.

3 for Tricorn/mandelbar

4 for weird line fractal with spider web julia sets

5 for Failed Möbius/Depressed mandelbrot

F goes into fullscreen

R resets.

J for julia set at the point where your cursor is.

SPACE prints position + zoom

B to toggle biomorphs

S to toggle smooth coloring

[&] to in/decrease biomorph value o&p to in/decrease bailout

planned stuff

general optimizations, like boundry tracing? (any help really appreciated) better controls

me complaining

I am a total C++ noob, so do not expect much. I do not know anything about glut, I used tutorials.

Screenshots

here are some epik screenshots using only this program (and the KDE screenshot thing)

I find this one interesting, with a lower bailout value + smooth colors, we get this pretty cool image of a Julia set of the Mandelbrot set.
