Fractal Friday 2020.01.24

This week I’ve been busy working on the MathPaint architecture so didn’t develop any obvious fractal rendering features… Though I did succeed in getting some optimizations in to speed things up, and the fractal renderer is now fully concurrent (using Cocoa OperationQueue and Operation objects.) This week I chose to explore another of my favorite … Read moreFractal Friday 2020.01.24

Fractal Friday 2020.01.17

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

Fractal Friday 2020.01.10

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

Fractal Friday 2019.12.20

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

Fractal Friday 2019.12.13

It’s Friday already! This week I’ve been jamming on this application UI development, including a brand-new feature to support fractals: the color mapping control: For fractal rendering the integers below each color correspond to the output value (escape iterations) to which the color is assigned. The linear-gradient mapping mode means that colors between these values … Read moreFractal Friday 2019.12.13

Fractal Friday 2019.12.06

The Mathaesthetics software has made some cool advances this week, and we’re celebrating with our first Fractal Friday video! These images depict a Julia set of degree 3 (function z^3 + C), with the C value 0.4+0.7i, 50 iterations maximum, and the escape value slowly changing with each image. The first image has escape value … Read moreFractal Friday 2019.12.06

Fractal Friday! 2019.11.29

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

Fractal Friday! 2019.11.22

This week’s images are mostly from the same region, x-axis: (-1.308, 0.567), y-axis (-0.542, 1.351). I started with the Douady rabbit – setting C to -0.123 + 0.745i, with max iterations for these renderings set to 32 and the escape radius set to 1000.0. Each of the following is produced by an adjustment to C … Read moreFractal Friday! 2019.11.22

Fractal Friday! 2019.11.15

This week I’m beginning a new series of postings, to celebrate the implementation of a fractal renderer in our flagship product – Fractal Friday! Click on each image to see it full size. These are window captures at screen resolution; our final product will also support higher resolutions and larger sizes. This first collection was … Read moreFractal Friday! 2019.11.15
