Title: Cortex Author: Nathan S Lachenmyer Date Started: July 2013 Last Modified: August 2013 =CORTEX= Cortex creates graphics based off of Kuver's form constants. The original paper documenting the mathematics can be found at the following URL: www.math.utah.edu/~bresslof/publications/01-1.pdf This program has been tested on Ubuntu 12.04 and OSX 10.8 =COMMANDS= Patterns can be activated and deactivated using the numeric keys: 1 - Vertical Bands 2 - Horizontal Bands 3 - Diagonal Bands 4 - Diagonal Bands (Alternate Direction) 5 - Arms 6 - Rings 7 - Spirals 8 - Spirals (Alternatve Direction) the subsequent row of letters (q,w,e,r,t,y,u,i) increase the speed of each pattern; the corresponding capital letters (Q,W,E,R,T,Y,U,I) decrease the speed by the same amount. The next row of letters (a,s,d,f,g,h,j,k) increases the frequency of the input sinusoid, changing the numbers of bands / rings / arms that appear in the pattern. The respective capital letter decreases the parameter. The last row of letters (z,x,c,v,b,n,m,,) swaps the direction of the pattern.
