FOTD -- May 01, 2010 (Rating 9.25) Fractal visionaries and enthusiasts: NEW FORMULA ALERT! Today's formula, FinDivBrot-2, is a new one. Actually, it's nothing more than a slight simplification of the FinalDivideBrot formula that eliminates some redundant minus signs and the awkward 0.00000...1 that was added to the imag(p1) parameter in the FinalDivideBrot, but had become extra baggage carried over from even earlier versions. The speed increase is insignificant if it exists at all, but the new formula certainly does look more compact and pleasing on the screen. The FinalDivideBrot formula is compatible with the new FinDivBrot-2 formula if the sign of the imag(p1) parameter is changed. There is no error in the rating of a 9.25 that I gave today's image. If I had actually created the colors from scratch, I might have rated it a 9.75 or even an exalted 10. As it is, with the program-created colors, the image is still, IMO, one of the best in FOTD history, and well worth its rating. The name "Lilacs in Bloom" refers to the colors of the lilacs blooming beside the front door of FC at this time of year. The parent fractal is strange indeed. It is little more than a circle with only hints of a fractal nature on its west side. In fact, if imag(p1) is reduced any significant amount at all, the entire parent disappears, leaving only a blank screen consisting of inside stuff. The ghost of the parent does still exist in this blank screen however, and can be made visible by rendering the scene with the inside set to an active inside fill, as I do with the 'evaporated' images, but in this case, the ghost image holds nothing worthwhile. The calculation time of 1-1/2 minutes is just about the FOTD normal. The finished image is available on the FOTD web site at: <http://www.Nahee.com/FOTD/> The high temperature of 82F 28C and the hot sun here at Fractal Central on Friday got no response at all from the fractal cats. As long the inside conditions are within their comfort range, they couldn't care less about the outside conditions. But except for those doing heavy work in the sun, Friday was near perfect. My day was within reason, which is reasonable enough. The next FOTD is due in 24 hours. As experience shows however, the Sat- urday images are frequently delayed by an unexpected antiquing trip. Until whenever, take care, and enjoy all FOTD fractals, even the handicapped ones.
