Hi,
I'm very new to processing. Could I get some help/advice on how to translate this sketch into a 3D language?
Thanks in advance!
import processing.opengl.*;
ArrayList points = new ArrayList();
Boolean md = false;
void setup(){
size(800,600,P3D);
background(255);
smooth();
//noStroke();
}
void draw(){
if(md){
for(int f=0; f<500; f+=1){
//for(int g=0; g<height; g+=height/10){
points.add(new Point(random(0,width),random(0,height)) );
//}
}
}
//fill(255,10);
//rect(-1,1,width+1,height+1);
//background(255);
noiseDetail(8,0);
//noiseSeed(1);
for(int i=points.size()-1; i>0; i--){
Point p = (Point)points.get(i);
p.update();
if(p.finished){
points.remove(i);
}
}
println(points.size());
}
void mousePressed(){
md = true;
}
void mouseReleased(){
md = false;
}
void keyPressed(){
background(255);
noiseSeed(round(random(1000)));
for(int i=points.size()-1; i>0; i--){
Point p = (Point)points.get(i);
//p.x = random(width);
//p.y = random(height);
points.remove(i);
}
//saveFrame("perlin####.png");
}
class Point {
float x,y,xv = 0, yv = 0;
float maxSpeed = 3000000;
Boolean finished = false;
Point(float x, float y){
this.x = x;
this.y = y;
}
void update(){
stroke(0,16);
float r = random(1);
this.xv = cos( noise(this.x*.01,this.y*.01)*TWO_PI );
this.yv = -sin( noise(this.x*.01,this.y*.01)*TWO_PI );
if(this.x>width){
//this.x = 1;
this.finished = true;
}
else if(this.x<0){
//this.x = width-1;
this.finished = true;
}
if(this.y>height){
//this.y = 1;
this.finished = true;
}
else if(this.y<0){
//this.y = height-1;
this.finished = true;
}
if(this.xv>maxSpeed){
this.xv = maxSpeed;
}
else if(this.xv<-maxSpeed){
this.xv = -maxSpeed;
}
if(this.yv>maxSpeed){
this.yv = maxSpeed;
}
else if(this.yv<-maxSpeed){
this.yv = -maxSpeed;
}
this.x += this.xv;
this.y += this.yv;
line(this.x+this.xv, this.y+this.yv,this.x,this.y );
}
}
