Logico Fractatus | Bad Fractals – Part 2

G’day, O fine humans! For this installment, I’ve another Bad Fractal, with its less-than-awful twin following. I’ll first show what’s wrong with the image, then tell you how I fixed it in the second take . . . .

This one looks innocent enough, but here, note the tiny silvery dot at the origin point, right at the center of the picture. I’ve used orbit traps with both of these pictures, but in the image above, they are too small, and the very largest of them can barely be seen, while the others are invisible! While the color mapping (the algorithm that assigns a color to each point in the image) is not that bad, the pseudo-3D effect of the orbit traps is useless and mars the image. So . . .

. . . With this one, I magnified the orbit traps up to 500 times the base size, and chose circular traps with just the right coloration to look like an eyeball with jointed tentacles. I’ve left the exterior regions unchanged, at least in this version. In Fractal Domains, the app I used for these, the circle and square orbit traps are the smallest for some shapes, and often require being scaled up much more drastically than stalk orbit traps based on real or imaginary number coordinates, those points on the complex number plane used to render the fractals. I’ve also reduced the number of colors available, keeping the image from being too busy or blurring into each other and spoiling the lines of the image!

So, I’ll be back soon with more Bad Fractals and their less-awful mirror-universe counterparts, and until then,

Tf. Tk. Tts.

Mr. Eccles Presents | The Nature of Sound – Symphony of Science

A journey into the world of sound and music with Brian Greene, Bill Nye, Yehudi Menuhin and more. Sound has always fascinated me – the way mere vibrations in the air can evoke such strong emotions, and how humans create our own meaning from arbitrary motion of molecules. We are like gods, building huge cathedrals of sonic beauty from minute, invisible physical forces that surround us. Download the song here:… More videos at: Follow & subscribe: @musicalscience
