Hi Guys,

I'm new to Processing so probably a fairly basic question but:

I have set up a 3D arraylist of nodes (points within a boundarybox).
I need to draw fibres (lines) between each node on the x axis moving incrementally along the y and z axis. I have created a very primitive fibre class...do I need to create a nested for loop to extract the necessary points?

Thanks,

Farley

void setup() {

 nodeArray = new ArrayList();

  for(int i = 0; i < numGroundX; i++) {
    for(int j = 0; j < numGroundY; j++) {
      for(int k = 0; k < numGroundZ; k++) {
        Vec3D nodeOrigin = new Vec3D((i+0.5) * envX/numGroundX, (j+0.5) * envY/numGroundY, (k+0.5) * envZ/numGroundZ);
        Node tmpNode = new Node(nodeOrigin);
        nodeArray.add(tmpNode);
      }
    }
  }

void draw() {

background(0);
 for(int i = 0; i < nodeArray.size(); i++) {

    Node tmpNode = (Node) nodeArray.get(i);
    tmpNode.display();
  }


void display() {
    stroke(255,0,0);
    strokeWeight(1);
    point(nodeLoc.x,nodeLoc.y,nodeLoc.z);
  }
