First of all, it defined the appropriate data structure for saving the iteratively complex mapping family: z←F(zw) +c(w = α +βi) , among which F(zw) standed for the either complex polynomial. Then, respectively basing on the fundamental idea of the Newton-Raphson, time-escaped and trap fractal algorithms while combining the elementary theory of chromatics, it proposed the specific method of the computer modeling the nonlinear-complex mapping family generating the generalized Julia sets. The lots of fractal simulation graphics, which were original pattern and delicate structure and rich coloration, not only verified the algorithms efficiency but also provided the extensive prospect to innovative designing the product's anti-counterfeiting marks.
