Laris I What is it ? : The Laris I formula is inspired by the "Barnsley" formula. It computes a parameter (p) at each iteration depending on the real part of z (ie if z is currently left or right from a vertical line). This parameter can be inserted in different way in a standard M-set (or Julia) formula. You can specify it's value left from the line and right from the line. It's also possible to make the parameter vary smoothly. In this case, it's value on the line must be specified. The Parameters : Formula type : Choose how you want p to perturb the standard M-set or Julia formula. Inside mode : Specify how p vary left from the line. With the "Raw" mode, p equals "inside parameter" whenever it's left from the line. "Smooth" interpolate it linearily so that p equals "Middle parameter" on the line. "Very smooth" do basically the same thing with a more elaborated formula. "Mistake" is just a mistake that I found interesting... Outside Mode : Works exactly the same as "Inside Mode", but is used when p falls on the right of the line. Inside\Outside Spin : Multiply p by a factor exp(i*pi*). This should twist the whole fractal. Inside\Middle\Outside parameter : Value assigned to p left from\on\right from the line. See "Inside Mode". Critical point : Allow you to move the line horizontally (the line will be x = ). This formula is interesting because of the great variety of spirals it can display.         Laris II What is it ? : This formula is based more or less on the same idea as Laris I. A perturbating parameter p is included in the M-set or Julia formula. Here the parameter is computed using the Triangle Inequality Average algorythm (from Damiens Jones). The Parameters : Formula type : Choose how p will perturbate the standard formula. Transfer Mode : Just a remark : The "Product" transfer mode will be useless if "Default parameter" is 0. Magnitude : The strength of the perturbation. There is not much interesting to say about the other parameters, just try them...         Laris III What is it ? : This formula is based more or less on the same idea as Laris I. A perturbating parameter p is included in the M-set or Julia formula. Here the parameter is computed using the Julia algorythm. The Parameters : Formula type : Choose how p will perturbate the standard formula. Spin : Will distort shape. Julia Set : Determine which Julia set will be used as trap. You can choose between nine "ready to use" Julia sets (1,2,...,9) and a "custom" julia set which will use as seed what you enter in the "seed" parameter. Center\Rotation\Size allow you to move\rotate\magnify the Julia set.
