Method

- set up webcam

- start Processing prog.

- set pixelsize in prog to 1

- saveFrame when frame is filled.

- press ‘run’

- go about and do your daily stuff

- after an hour or two, watch the result.

what to think of this? Should I then finally switch to chrome?

circle software

A first comparison between two software apps: Processing and Elise. (more to come). In Processing, the trouble I often experience is the missing relation between code and action: between first thinking in code before checking the result visually). In this small experiment, the assignment was to create a circle using repetitive patterns. As you can see in Elise, by simply creating one branch of the LSystem, a direct visual feedback is given on what you have crated. By altering the angle or the number of iteration, patterns start emerging and visuals are born.

Circles in Processing

code:

import processing.opengl.*;
int x=1;
int y = 1;

void setup(){
size (400,400, P3D);
background (255);
smooth();
}
void draw(){
translate(200,200,y);
//rotateZ( sin(x));
ellipse((sin (x)*100),(cos (y)*100), x,y);
for(int i= 0;i<1;i++){

if(x>=100&&x<=200){
x++;
y++;

}
else{
x–;
y–;

}
}
}

Circles in Elise.

This program made by Alexander Rulkens, uses L-systems to create very beautiful repetitive (recursive) visuals. This is just one example (Lissajous):
