rep_chirikov_taylor

Arguments:

  • size!=0,_lines>0,_pts_per_line>0,_k,_chirikov_mode={ 0=standard | 1=chirikov_karimov },_offmode={ 0=default | 1=center },_orientation={ 0=xy | 1=yx },_use_parallel={ 0=serial | 1=parallel }

Description:

Creates Chirikov discrete map. Chirikov map can be the standard version which is created by Boris Chirikov or modification done by Artur I. Karimov.

(equivalent to shortcut command rep_cstdmap).


size can be either in percent or integer. It can be negative or positive. Percentage mode is always based on the size of image. Positive values will lead to square value regardless of initial image. Negative value will create a new image based on whether the width or height is smaller, and scale based on the ratio of max dim vs min dim.
_lines defines the number of lines created within image. It defaults to 1 if the user inputs a value in which the absolute of value is less than 1.
_pts_per_line defines how much points is generated per lines.
_k can be considered distortion factor. It can be negative.
_chirikov_mode defines whether to apply a symmetric modification to the original version of chirikov standard map. The symmetric modification is based on the paper 'The Study of the Modified Chirikov Map' by Artur I.Karimov, Denis N. Butusov,Vyacheslav G. Rybin, Timur I.Karimov within Department of Computer Aided Design at Saint Petersburg Electrotechnical University.
_offmode defines whether the main rotor will be centered.
_orientation defines whether to switch axis for generation of chirikov map.
 
Author: Reptorian.

Default values:

_lines=500,_pts_per_line=5000,_k=1,_chirikov_mode=0,_offmode=0,_orientation=0,_use_parallel=1
