Title: Pearls I Post by: Pauldelbrot on February 20, 2009, 03:24:46 AM (http://u5789.direct.atpic.com/25631/0/1238139/1024.jpg) (http://pic.atpic.com/1238139/1024) A Kleinian group fractal with shaded balls for the "pearls". The shading is achieved by using two layers. The image was rendered in four pieces, assembled into a 4096x3072 image, and downsampled to get rid of artifacts and improve detail over and above what anti-aliasing does. During the calculation, nearly 1GB of RAM was needed; trying to render the thing in one piece (or at 2048x1536 with depth-2 antialiasing) produced actual honest-to-God out-of-memory errors.
