The resemblance is only superficial, ; for at the odd angle of today's image, no midgets are possible. ; ; The image is an odd slice of the open rectangle that appears in ; the C=-1.7435,0.0 Julia set of the Z^2.003+C fractal at Z coordi- ; nates 0.00019,0.07388. This unexpected and near perfect rectan- ; gle is one of my favorite fractal objects, one to which I often ; return. Its actual four-dimensional shape would appear to a 4-D ; person as a 2-D hole, with two extended dimensions and the ; remaining two dimensions very small, much as a sheet of paper in ; our 3-D world has two extended dimensions and one small ; dimension. ; ; Since two of its four dimensions are so small, this open area ; appears as a rectangle only when sliced in the Julia direction ; and at the exact C coordinates. The slightest rotation or ; imag(C) deviation totally destroys its straight edges and sur- ; rounding symmetry. At today's angle, the symmetry is totally ; destroyed. ; ; I named the image "Firefall" because, with a little imagination, ; it shows fire spewing from the ground and falling over a cliff. ; Others may see something else, but the falling fire is all I can ; see. The rating presented little problem. The slightly-above- ; average 6 seems just right. ; ; The image is a fast one, requiring only 2-1/4 minutes to render ; from the parameter file, on my worn-out machine. About the same ; time will be required to go online and download the completed ; GIF image from Paul's web site at: ; ; ; ; or from Scott's site at: ; ; ; ; Freezing rain, followed by heavy rain and melting snow brought ; flooding, fallen trees, power outages, and a roof leak to the ; Fractal Central area Wednesday. By evening, the high tempera- ; ture of 36F 2C had melted most of the ice that had built up on ; trees and sidewalks. Conditions were so bad outdoors that the ; intrepid cats were thankful to be permitted to remain indoors ; all day. The roof leak will require further investigation. ; ; Today is starting much improved, but I expect a lot of work ; before the day is finished, which might cut into my fractal ; time. To see how things work out, check back here in 24 hours, ; when the next FOTD will appear almost by magic. Until then, ; take care, and beware of fractal brimstone. ; ; ; Jim Muth ; jamth@mindspring.com ; jimmuth@aol.com ; ; ; START PARAMETER FILE================================ Ongoing_Eruption { ; time=0:02:17.75--SF5 on a P200 reset=2002 type=formula formulafile=allinone.frm formulaname=multirot-XZ-YW-new center-mag=-0.01885\ 870562667460/-0.00508405854824132/96.13768/0.1758/\ -180/-72.5978701069904417 params=98/-8/2.003/0/0.0\ 0019/0.07388/-1.7435/0 passes=1 float=y maxiter=2500 inside=atan periodicity=0 colors=000UGWTETWCSTCPSAORAMP8KO7JM6HK5HJ4HI4GH4GG\ 4GE4FD4FC4FA4EA4E74D64D54D44C34C24C24A44A64A84AA4A\ D5AF6AG7CH8CIA7JADKCEMDENEFOFFPFGRFFSFFTFEUFEWFDXE\ DYECZEC`EAaEAbEAcEAeE8fE8gE7iE7jE6lE6mE5nE5pE4qD4s\ D3tD3uD2wE2xG2yI2zK1zM1zO0zQ0zS0zU0zW0zY0zZ0z_2z`5\ yaAxbEwcIxdNyeOzfOzgOzgOzgOzgOzgOzhOziOzkOzmOztOzz\ OzmOz`OzOOzJOxKOuNOsMOpMOmMOjMOjMOlMNlMNlMNlKMlKMm\ KKmKKmKKmKJmKJnKJnJInJInJInJHpJHpJGpJGpJGpIFqIFqIF\ qIEqIEqIEsIDsIDsHCsHCsHCtHAtHAtHAtHAtHAtHAtIAtJCtK\ DsMEsMFsNGsOHsPHqRIqRJqSKqTMpUNpWOpWPpXRpWSnTTnRUn\ OWnMXnKXmJYmIZmH`mGalFblEclDelC0lA0jA0j80j80jA0jA0\ iCSiDViEZiFciGcgHcgIcgJcgKegMgfNffKffIffGefEefCeeA\ ceAceAccAccAcc8cc8bb8bb7bb7ba7ba6ba6aa6a`5a`5a`5aZ\ 4aZ4aZ4`Z3`Y3`Y3`Y2`X2`X2ZX2ZX2ZW2ZW1ZW1ZW1ZX2YX3Y\ X4YX6XX7XX8XXAXXCWYDWYFWYGWYHUYIUYKUYMTYNTZPTZRTZS\ SZUS`KZ`KYZJYYIYXIXXHXWGX } frm:multirot-XZ-YW-new {; Jim Muth ; 0,0=para, 90,0=obl, 0,90=elip, 90,90=rect e=exp(flip(real(p1*.01745329251994))), f=exp(flip(imag(p1*.01745329251994))), z=f*real(pixel)+p3, c=e*imag(pixel)+p4: z=z^(p2)+c, |z| <= 36 } ; END PARAMETER FILE================================== ; ;
