Andrew YoungUpdated my mandelbrot app to display in 256 colors by default and switched it to use the Classic Mac color palette. When you run xmandelbrot you can now pass it a number from 1-256 to tell it how many iterations (and thus how many colors) to use. Here it is running on my Quadra 700 under A/UX with a 68040 CPU.

Andrew YoungI added an X11 version of my mandelbrot program. This one is in color and is resizable! It runs on A/UX and will probably run on any version of UNIX that runs X11. I've attached screenshots from A/UX and modern Linux. You can find the code on github along with the console version: <a href="https://github.com/vaelen/multi-mandlebrot/tree/main/unix" rel="nofollow noopener" target="_blank">https://github.com/vaelen/multi-mandlebrot/tree/main/unix</a> <a href="https://bitbang.social/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#retrocomputing</a> <a href="https://bitbang.social/tags/unix" class="mention hashtag" rel="nofollow noopener" target="_blank">#unix</a> <a href="https://bitbang.social/tags/mac" class="mention hashtag" rel="nofollow noopener" target="_blank">#mac</a> <a href="https://bitbang.social/tags/x11" class="mention hashtag" rel="nofollow noopener" target="_blank">#x11</a> <a href="https://bitbang.social/tags/mandelbrot" class="mention hashtag" rel="nofollow noopener" target="_blank">#mandelbrot</a>

The final color is produced by interpolating between these three colors using the so called "atom domains".Generated using my GLSL Shadertoy fractal generator: <a href="https://www.shadertoy.com/view/33sSRf" rel="nofollow noopener" translate="no" target="_blank">https://www.shadertoy.com/view/33sSRf</a><a href="https://mathstodon.xyz/tags/Mandelbrot" class="mention hashtag" rel="nofollow noopener" target="_blank">#Mandelbrot</a> <a href="https://mathstodon.xyz/tags/Fractal" class="mention hashtag" rel="nofollow noopener" target="_blank">#Fractal</a> <a href="https://mathstodon.xyz/tags/Art" class="mention hashtag" rel="nofollow noopener" target="_blank">#Art</a> <a href="https://mathstodon.xyz/tags/Fractalart" class="mention hashtag" rel="nofollow noopener" target="_blank">#Fractalart</a> <a href="https://mathstodon.xyz/tags/Mathart" class="mention hashtag" rel="nofollow noopener" target="_blank">#Mathart</a> <a href="https://mathstodon.xyz/tags/GLSL" class="mention hashtag" rel="nofollow noopener" target="_blank">#GLSL</a> <a href="https://mathstodon.xyz/tags/Shadertoy" class="mention hashtag" rel="nofollow noopener" target="_blank">#Shadertoy</a>

But I wanted to also be able to click around in the Julia set and see how the Mandelbrot set changed.Really both the Mandelbrot and Julia sets are two dimensional cross sections of a four dimensional fractal. A point (x,y,a,b) is in this set if the function z ↦ z²+(x+yi) doesn't diverge when iterated starting at a+bi. My app lets you see the slices of (x,y) for fixed a and b, and also (a,b) for fixed x and y.I don't write JavaScript, so all code is bad and/or stolen.<a href="https://mathstodon.xyz/tags/Math" class="mention hashtag" rel="nofollow noopener" target="_blank">#Math</a> <a href="https://mathstodon.xyz/tags/Maths" class="mention hashtag" rel="nofollow noopener" target="_blank">#Maths</a> <a href="https://mathstodon.xyz/tags/Mathematics" class="mention hashtag" rel="nofollow noopener" target="_blank">#Mathematics</a> <a href="https://mathstodon.xyz/tags/Mandelbrot" class="mention hashtag" rel="nofollow noopener" target="_blank">#Mandelbrot</a> <a href="https://mathstodon.xyz/tags/MandelbrotSet" class="mention hashtag" rel="nofollow noopener" target="_blank">#MandelbrotSet</a> <a href="https://mathstodon.xyz/tags/Fractal" class="mention hashtag" rel="nofollow noopener" target="_blank">#Fractal</a>
