Adam Majewski Fractal Frogurt Offline Posts: 405 November 19, 2020, 03:28:05 PMI'm glad you like it.Binary Decomposition ( of target set for escape time)  https://en.wikibooks.org/wiki/Fractals/Iterations_in_the_complex_plane/Julia_set#Binary_decompositionalso boundaries of BD is used by Claude :https://commons.wikimedia.org/wiki/File:Mandelbrot_set_-_wake_1_over_31_with_external_rays.png Adam Majewski Fractal Frogurt Offline Posts: 405 November 19, 2020, 03:32:55 PMHere is the most important part or code ( c) : Code: [Select]unsigned char ComputeColorOfBD(complex double z){ int nMax = iterMax_LSM;  double cabsz;  unsigned char iColor;   int n;  for (n=0; n < nMax; n++){ //forward iteration cabsz = cabs(z);    if (cabsz > ER_LSM) break; // esacping    //if (cabsz< PixelWidth) break; // fails into finite attractor = interior but not for disconnected Julia sets, then critical point and its preimages  !!!!           z = z*z +c ; /* forward iteration : complex quadratic polynomial */   }    if (cimag(z)>0.0)   iColor = 255;   else iColor = 0;    return iColor;}Here is full code ( on that page, below the image ) :https://commons.wikimedia.org/wiki/File:Imploded_cauliflower_DLD.png
