I was thinking if there is an easy way to bend or twist or transform along a path, a helix like object i created.

Its for an upcoming data visualisation but i dont want it to be straight . Some turns would be nice.

In this thread, Dave mentioned, PMatrix but i was not sure if this would be an option in this case. Like i said, in the other post. I wish there would be some more documentation on PMatrix, as i coulnt find any beside the javadoc.

So what do you think, any easy way to bend the following?



Code:

  import processing.opengl.*;

void setup(){
  size(600,600,OPENGL);
}

float rx,ry;
void draw(){
 
translate(0,200,0);
rx+=((width/2-mouseX)*0.01f-rx)*0.1f;
  ry+=((height/2-mouseY)*0.01f-ry)*0.1f;
  rotateY(rx);
  rotateX(ry);

  randomSeed(10);
  background(241);
   noStroke();
  smooth();
  translate(width/2,height/2);
  segment(260 ,0,3600,60);

}
void segment(int resolution,int start, int end, int radius){
  beginShape(QUAD_STRIP);
  for(int i=0;i<resolution;i++){
    float d=radians(map(i,0,resolution-1,start,end));
   fill(map(i,0,resolution,0,255));
	float xx = random(1.2,6.5);

   float lerpX = map(xx,1.2,6.5,0,1);
//   fill(lerpColor(#ff0000,#4400ff,lerpX),100);
   fill(255-xx*170,20);
  
   strokeWeight(0.4);
   stroke(lerpColor(#ff0000,#4400ff,lerpX));
    fill(map(i,0,resolution,255,0),0,200);
noStroke();
    vertex(sin(d)*(radius),cos(d)*(radius), i*4 );
    vertex(sin(d)*((radius+5)+10),cos(d)*((radius+5)+10), i*4 );
  }
  endShape();
}
