### Welcome

Gregory B. Searle is a digital computer artist with a Bachelor in Fine Arts
from the University of Lowell (now U-Mass at Lowell) and a computer
programming background. He combined these seemingly opposing skill-sets
to create unique computer-generated “fractal” imagery using his own
custom computer code. This allows him to explore a whole world of
mathematically-generated imagery, carefully crafting the limitless
parameters to produce one-of-a-kind, high-quality fractal prints.
This page is intended as a space to explore computer-generated *fractal*
imagery as an art form.

At this time I am concentrating on extended variations of the
*Mandelbrot set*. In the future I may explore other types
of fractals. The extended set provides a huge world of form and
texture to explore. See the *About Fractals* page for more
information.

### Extended Precision

*Deep zoom into the “Burning Ship” fractal*

This application now supports *extended precision*
calculations for deeper zooms into the fractals. Normally, the
image starts to break down into blocks when you approach the
double-precision limit of the CPU when zooming in. This occurs
at about 10^{14} magnification (1 followed by 14 zeros),
or 100 *trillion* times.

A technique called *double-double precision* allows
this limit to be extended to around 10^{30} magnification
(1 followed by 30 zeros), or a *nonillion* times. This
provides a lot more headroom for exploration! The above image was
found deep in the “Burning Ship” fractal at one
septillion, or 10^{24} zoom.

### New Artwork

A variant of the Mandelbrot set takes the absolute value of the formula on each iteration. The result is very different. This is a deep magnification of the “Burning Ship” fractal. It looks like you are looking upward through rippling water at an old cityscape. This fractal tends to be noisy, so rendering required 16X supersampling to smooth it out.

### “Special Merit” and “Special Recognition”

*Champagne* received Special Merit and *Bluebird* received Special Recognition in the the March 2017 Light Space & Time
Online Art Gallery's 8th Annual Abstracts Art Exhibition. Following are a couple of excerpts from
the gallery:

“The gallery received 887 entries from 36 different countries from around the world. In addition, the gallery received entries from 38 different states.”

“The gallery also included Special Merit awards and Special Recognition awards for outstanding art. Many of the artists in either of these groups could have easily been included in the upper tier of our winners, as their art was also exceptional.”

Previously, *Dragon Scales*, also won Special Merit in the October 2016 “Open” exhibition.
