Hello processing community,

As a good tinkerer, ive been bumping my head on it the whole day. Using this http://processing.org/learning/3d/shapetransform.html.
i would like to make an array of those solids moving on a 2D space, like the little red dots. It just does it for the first solid, so i guess this is an issue with the for... loop. Can you help me out

Code:

int pts = 3, i;
float angle = 0;
float radius = 10;
float cylinderLength = 10;
//vertices
PVector vertices[][];
boolean isPyramid = false;
float angleInc;

int max_Agents = 100, Agents = 20;
float inc = 0.0045; // speed

float[] ptsX = new float[max_Agents];
float[] ptsY = new float[max_Agents];
float[] posX = new float[max_Agents]; 
float[] posY = new float[max_Agents];   

int frameX = 640, frameY = 480;

void setup(){
  size(frameX, frameY, P3D);
  noStroke();

  angleInc = PI/300.0;
  
    // set arrays
  for (int i = 0; i < max_Agents; i++) {
    ptsX[i] = random(0, frameX);   // write start pts to arrayX
    ptsY[i] = random(0, frameY);   // write start pts to arrayY
    posX[i] = ptsX[i];
    posY[i] = ptsY[i];
  }
}

void draw(){
  background(0);
  lights();
  fill(255,0,0);
  stroke(1);

  for (int i = 0; i < Agents; i++) {
    posX[i] = noise(ptsX[i]) * frameX; 
    posY[i] = noise(ptsY[i]) * frameY;

    ptsX[i] = ptsX[i] + inc; 
    ptsY[i] = ptsY[i] + inc;
    
    ellipse(posX[i], posY[i], 10 , 10 );   
  }
    
  translate(posX[i],posY[i]);
  rotateX(frameCount*PI/185);
  rotateY(frameCount*PI/-200);
  vertices = new PVector[2][pts+1];
  fill(200,200); 

  // fill arrays
  for (int m = 0; m < 2; m++){
    for(int n = 0; n <= pts; n++){
      vertices[m][n] = new PVector();
      if (isPyramid){
        if (m==1){
          vertices[m][n].x = 0;
          vertices[m][n].y = 0;
        }
        else {
          vertices[m][n].x = cos(radians(angle)) * radius;
          vertices[m][n].y = sin(radians(angle)) * radius;
        }
      } 
      else {
        vertices[m][n].x = cos(radians(angle)) * radius;
        vertices[m][n].y = sin(radians(angle)) * radius;
      }
            
      vertices[m][n].z = cylinderLength; 
      // the .0 after the 360 is critical
      angle += 360.0/pts;
    }
    cylinderLength *= -1;      
  }
  // draw cylinder tube
  beginShape(QUAD_STRIP);
  for(int n = 0; n <= pts; n++){
    vertex(vertices[0][n].x, vertices[0][n].y, vertices[0][n].z);
    vertex(vertices[1][n].x, vertices[1][n].y, vertices[1][n].z);
  }
  endShape();

  //draw cylinder ends
  for (int m = 0; m < 2; m++){
    beginShape();
    for(int n = 0; n < pts; n++){
      vertex(vertices[m][n].x, vertices[m][n].y, vertices[m][n].z);
    }
    endShape(CLOSE);
  }      
  } 

Thank you very much Ramin, this helped me quite a lot.
I wonder though : using this class structure with a vector, can i still connect all the balls / volume with a network of lines. I did it using this nested loop on the previous code :

 for (int i = 0; i < Agents; i++) {
   for (int j = i; j < Agents; j++) {
     if (dist(posX[j], posY[j], posX[i], posY[i]) < 50) {
       line(posX[j], posY[j], posX[i], posY[i]);
     }
   }
 }

I would like to know why you rename the coordinate as pos.x/pos.y and if i can still write something like pos.x[i].

thanks!
