How can I get started on 3D point clouds?

in General Discussion • Other • 1 year ago

Inspired by the recent "unnamed soundsculpture" piece I want to learn more about 3D point clouds. Any suggestions on how to get started? Any libraries I should use or documents I should read? Any suggestions is appreciated. Cheers.

Here, I wrote you a starter point cloud:

class Point {
PVector p;
PVector v;
color c;
Point( PVector _p ){
p = _p;
v = new PVector( random(-.01,.01), random(-.01,.01), random(-.01,.01) );
c = color( random(255),random(255),random(255) );
}
void process(){
//simulate();
render();
}
void simulate(){
p.x+=v.x;
p.y+=v.y;
p.z+=v.z;
p.x%=1;
p.y%=1;
p.z%=1;
}
void render(){
stroke(c);
point( p.x, p.y, p.z );
}
}
Point[] points = new Point[5000];
void setup(){
size(400,400,P3D);
for( int t=0; t < points.length;t++){
points[t] = new Point( new PVector( random(-1,1), random(-1,1), random(-1,1) ) );
}
}
void draw(){
background(0);
translate(width/2.0,height/2.0);
rotateX(map(mouseY, 0,height-1, -PI,PI));
rotateY(map(mouseX, 0,width-1, -PI,PI));
scale(100);
noFill();
stroke(255);
box(2);
for( int t=0; t < points.length;t++){
points[t].process();
}
}
