Something Like Vines

Some new processing work. click the mouse to change the colors and start new shoots growing. This has a really cool texture if you render it at the high resolution. Here is the source code if anyone is interested.

Here are a few screen grabs from versions that looked cool along the way:

int isBig=1;       // 0 is 500x500 big is 5000x5000
//int dimx = 6000 ;   // width
//int dimy = 6000 ;   // height
//int num = 2000;    // number of hairs
//int startDist = 10;   // minimum distance out
//int endDist =1500;    // maxumum distance out
//int colorChange=300; 

int dimx = 400 ;   // width
int dimy = 400 ;   // height
int num = 500;    // number of hairs
int startDist = 1;   // minimum distance out
int endDist = 75;    // maxumum distance out
int colorChange=60; 

int brushWidth = endDist-startDist;   // differehce between them is the drawing zone.
