Fractal of the Day

Fractal visionaries and enthusiasts: Things are still hopping here at F.C., so once again the discussion will be short. Today's image lies in the parent fractal that results when some Z^(-2) is subtracted from some just plain Z and (1/C) is added. This parent appears as a vague Mandeloid rotated -120 degrees. Its most identifiable feature is its East Valley, which in this case lies on the NNW border of the main bay, a feature that could more accurately be called the ocean, for there is little resemblance to a bay. I named the image "Erin Land". For some reason, most likely its overall green color theme, the image reminds me of Ireland. For variety, I used the outside=atan option in rendering the scene. It gives a livelier appearance than the basic and overworked outside=iter option. The colors are rather brilliant, a fact that I noticed when I gave the scene its rating of a liberal 7. Unfortunately, the slow render time of almost 52 minutes permits an overall value of only 13. But the image is still interesting, and as always, will soon be available on the FOTD web site at: The near-perfect weather here at Fractal Central over the past few days kept the fractal cats quite happy. Today is progressing near perfectly also, so I expect more happiness from the cat quarter. For me, I think I see light at the end of the work backlog tunnel, but there is still a way to go. It looks like the next FOTD will appear on Sep 15. Until then, take care, but don't take so much care that you take away all the fun. Jim Muth jamth@mindspring.com jimmuth@aol.com |
