复分形的分块作色尝试

看了分形艺术程序设计一书中关于颜色一节，尝试自定义对复分形图形作色，不很完美，颜色基本能事先控制，有些不成熟经验，今公布文件于此，问题很多，欢迎行家批评指正。大家有好的作色法,也可交流,并发源文件在此,大家彼此学习,共同提高.

#1、#2楼的着色效果不错，如果能做到象#2楼紫色那块的效果是最好的（收敛终点处颜色保持浅色，周围向外逐渐加深。链条又能突出显示）。

UF中系列amm.ufm中的General_Sterling_19：
General_Sterling_19 {

; Original: z - (z*z*z+c*z*z+z+c-zsin)/(3*z*z+2*c*z-zcos)

init:
  float zds
  complex z1
  complex z2

if @usepixel
z = #pixel*@seed
  else
;Original From Sterling
z = @seed
  endif

loop:
  z1 = z
  z2 = z^2
  zcos = (1e-15+@fn2(z))/@strands1
  zsin = (1e-15+@fn1(z))/@strands2

  z = z-(@p1*z*z2+@p2*#pixel*z2+z+@p3*#pixel-@p4*zsin)/(3*z2+2*#pixel*z-zcos)
  zds = |z1-z|

bailout:
  (zds > 1e-25) && (zds < 1e20)

default:
  title = "General_Sterling_19"
  periodicity = 0
  maxiter = 130
  center=(1.873215435,0.98183099)
  magn=0.072802863


  float param Seed
caption = "Seed"
default = -1/3
  endparam

  complex func fn1
caption = "Fn1"
hint = "This is the first function."
default = sin()
  endfunc

  complex func fn2
caption = "Fn2"
hint = "This is the Second function."
default = cos()
  endfunc

  complex param p1
caption = "p1"
default = 1
  endparam

  complex param p2
caption = "p2"
default = 1
  endparam

  complex param p3
caption = "p3"
default = 1
  endparam

  complex param p4
caption = "p4"
default = 1
  endparam

  complex param p5
caption = "p5"
default = 1
  endparam

  complex param p6
caption = "p6"
default = 1
  endparam

  complex param p7
caption = "p7"
default = 1
  endparam

  complex param p8
caption = "p8"
default = 1
  endparam

  float param strands1
caption = "Strands 1"
default = 0.05
  endparam

  float param strands2
caption = "Strands 2"
default = 0.05
  endparam

  complex param ex1
caption = "Exponent 1"
default = 2
  endparam

  complex param ex2
caption = "Exponent 2"
default = 2
  endparam

  complex param ex3
caption = "Exponent 3"
default = 2
  endparam

  Bool param usepixel
caption = "Use Pixels (C*Seed)"
default = True
  endparam
}
我一直想把它分块着色，但由于收敛点不定始终没办法实现，请柳老师有兴趣的话试试：
