FOTD -- October 15, 2005 (Rating 5) ............ It was created with an old formula written back in 1998 by Jay Hill....
frm:MixUp {; (c) Jay Hill, 1998 ; make sure p1 <> p2 and p3 <> 0 u=p1, v=p2, w=p3, c=pixel/w, x=v-u, z=(-u/v/w)^(1/x): z=z^u + w*z^v + c |z| <= 1000 }
Concerning the above formula, I was wondering if it should/might be renamed to something like "MixUpJ2"?? Especially since the ORGFORM collections (both the old 1999 version on Spanky, and the current on at http://home.att.net/~Paul.N.Lee/OrgForm.html ) have different "Mixup" formulae already available: mixup { z=fn1(pixel): z=sqr(z)+fn2(pixel) |z|<= 4 ;SOURCE: test.frm } MixUpJ {; (c) Jay Hill, 1998 ; make sure p1 <> p2 and w <> 0 u=p1, v=p2, x=v-u, w=.5 c= p3 ; Julia parameter z=pixel; critical z=(-u/v/w)^(1/x) : z=z^u + w*z^v + c |z| <= 1000 ;SOURCE: 98msg.frm } Sincerely, P.N.L. ------------------------------------------------- http://home.att.net/~Paul.N.Lee/PNL_Fractals.html http://www.Nahee.com/Fractals/
