Points leaving trail in 3D

Programming Questions

Hey guys I'm very new to processing, I just sketched some points moving in 3D I want them to leave a trail behind but I'm not sure how to code it.
I think this is the basic concept:
I need to get all PVector of the points moving then put them in Arraylist.
Then from the Array list of PVector I can loop to draw points.
Later on I want to use the points as a attractor to other agents.
This sounds easy but very hard as I only have limited amount of processing knowledge.
Someone please help!
Thanks in advance.

- ArrayList agentCollection;
- PeasyCam KCam;

- smooth();
- KCam = new PeasyCam(this,800);
- agentCollection = new ArrayList();
- for(int i = 0; i < 20 ; i++){
- speed = new PVector(random(-1,1),random(-1,1),random(-1,1));
- agentCollection.add(new agent(speed));
- }

- void draw(){
- background(255);
- box.display();
- for(int i = 0; i < agentCollection.size(); i++){
- agent thisagent = (agent) agentCollection.get(i);
- thisagent.run();
