I created this kaleidoscope starting from a fairly ordinary Mandelbrot spiral plotted in 3D.


(Be sure to click on the image to view the larger version in my PBase gallery. It looks better even bigger, but I didn't want to post that to the net.)

I've been toying with the idea of adding a kaleidoscope generator to FractalWorks. It's a bit "off topic" for a fractal renderer, but it would be handy. Animated fractal kaleidoscopes would be very cool. Imagine a kaleidoscope based on rotated and reflected triangular "slices" of a fractal image. Now imagine that the triangle is rotating and panning through the image, like a ball bouncing around in a 2D video game. As the triangle moves through the image, the area of the image it outlines becomes the source for the kaleidoscope. This should produce an effect rather like that with a real kaleidoscope.

Trifox,

Thanks,

I must confess, I cheat on the anti-aliasing. I create my images at double size, then downsample them in Photoshop using bicubic sharper. I haven't tackled anti-aliasing in my program yet.
