This fractal set made with MathPaint starts with a cubic Mandelbrot layer, warped by a quadratic function and blended with an underlying Perlin noise layer:
The MathPaint Variations window was used to generate randomized variations from this beginning, changing colors as well as parameters and blending:

Here are a few new fractals created with pre-release MathPaint. These are all either standard Julia or Mandelbrot z^2 sets, with a warp function applied to the real part and a custom color mapping. Enjoy! All images made by Christopher Corbell, ©2020 Mathaesthetics.
I started this week’s Fractal Friday exploration by trying out higher-iteration-cutoff Mandelbrot sets. Here are a few results with max iterations set to 1000, and higher breakout values than my usual setting of 10.0 – more detail definitely appears, especially in the boundary of the breakout value which becomes much more frond-like. The first one … Read moreFractal Friday 2020.02.21
This week I’m sharing the results of a cool new feature in MathPaint: fractals warped by real-valued functions. The application now supports defining a custom real-valued function that is applied during each iterative evaluation to the real part of the complex number ‘z’, before z is squared. The possible effects are endless – from slight … Read moreFractal Friday 2020.02.07
For this week’s post I’m showing off more of the rendering and layer-compositing options that are part of MathPaint. I’m using the same fractal settings for all of this week’s images – a Mandelbrot set with breakout value at 10.0, max iterations set to 200, and viewed at the (approximate) ranges [-1.432, -1.345] on the … Read moreFractal Friday 2020.01.31
This week’s images again come from some experiments with new features for MathPaint, the flagship software app I’m working on. Previously I posted some experiments with edge rendering in fractal geometry, where only the boundary between levels of output are drawn. It shows the boundary between iteration levels but does not indicate the level itself … Read moreFractal Friday 2020.01.17
ICYMI, I’m currently writing an application that generates mathematical art. It’s created in Swift, for Mac OS desktop systems. All the images on this blog are created from it, including the fractals posted every Fractal Friday. This week I hooked up a full range of CoreImage effects to the app, and I’m having fun sending … Read moreFractal Friday 2020.01.10
It’s the last Fractal Friday of the year, time for some recursive magic! This week we’re exploring the Mandelbrot set, using two features of the Mathaesthetics prototype software: deep color mapping, and a new helpful zoom feature. Here’s where we start: In this image, there’s a color mapping with 10 different colors at various levels … Read moreFractal Friday 2019.12.27
The fractal renderer used to draw this week’s graphics has a new feature – rendering in ‘edge’ mode. Rather than filling the value regions with different colors, edge-mode detects the change in output values and draws a line at the boundary between them. Here’s the classic Mandelbrot set rendered this way: Here’s a simple black-and-white … Read moreFractal Friday 2019.12.20
It’s Fractal Friday! As always you can click the images below to see them full-size. This week’s fractal images highlight two new features added to the application I’m developing: color cycles, and Nth-degree fractal expressions. A color cycle is an an array of colors used to render the fractal pixels. The renderer cycles through them … Read moreFractal Friday! 2019.11.29
