Hi Jim Just reading the formula for MandelbrotBC3, perhaps I'm missing something or have forgotten (it's been a while since I read the manual)...in the second line of the formula what is PI? It hasn't been defined? Is it 'p1' ? Alex Dukay

frm:MandelbrotBC3 { ; by several Fractint users e=p1, a=imag(p2)+100 p=real(p2)+PI q=2*PI*fn1(p/(2*PI)) r=real(p2)+PI-q Z=C=Pixel: Z=log(Z) IF(imag(Z)>r) Z=Z+flip(2*PI) ENDIF Z=exp(e*(Z+flip(q)))+C |Z|<a }
