Hi, I discovered Processing a couple of weeks ago, and I am really interested to learn it. My first attempt is to try to visualize sound. So far I have only managed to create a pattern based on the ellipse...
I have two questions for you:
1. I want to experiement more with the pattern, but my Processing skills are limiting me. Do you have any suggestions for what I might add to make it more visual interesting?
2. I also want to export a pdf when mousePressed, but the exported pdf looks really bad; it saves the pdf in a square (35mmx35mm) and it only saves parts of the graphics. Do you know what I do wrong?
I really appreciate if you would help me.
import processing.pdf.*;
PGraphicsPDF pdf;
import ddf.minim.*;
float x, y, r, g, b, radius;
int timer;
Minim minim;
AudioInput input;
void setup () {
pdf = (PGraphicsPDF)beginRecord(PDF, "Lines.pdf");
beginRecord(pdf);
size (1620, 440);
smooth();
fill (0);
strokeWeight(0.7);
x = 0;
y = 20;
minim = new Minim (this);
input = minim.getLineIn (Minim.STEREO, 512);
}
void draw () {
x = constrain(x,0,width);
y = constrain(y,0,height);
float dim = input.mix.level () * width;
x += input.mix.level () * 20;
// use frameCount to move x, use modulo to keep it within bounds
