Demos

These are some preliminary demos and previews of some ideas I am working on.

CanyonDeep Trial 1

Here is the long-awaited CanyonDeep trial run. This took over 15 days to render at a tiny resolution of just 160x120. Frame interpolation was used, so the number of frames actually calculated is far fewer than the 600 frames in the video. (It is about 100 frames at approximately 320x240.)

Sample snapshots

This region of the Mandelbrot set is no joke. The counts go up extremely fast here, and I quickly ran into the count limit of my software. Some parts of this image took over 200 million iterations to calculate each pixel. You can see some blank areas in the cores of some of the spirals where even this 200 million was not enough.

This little animation has a lot of technology behind it. It uses a variation of the Mariani-Silver algorithm to speed up rendering the large areas of the set as we approach the canyon. It was the first animation to benefit from the speedup of my high-precision multiplication functions. And it is the first animation I'm publishing with my new coloring technique. This technique produces a static color map (that is, a conversion from fractal data to colors that does not change as the animation progresses) that is tailored to the changing ranges of the fractal data. The technique is based on ideas inspired by high dynamic range photography, and it shows a lot of promise.

Phoenix Demos

The Phoenix demos have moved to the Henon/Phoenix page in the Still Images section.
