Hi, I am new to Processing and am trying to randomly select a PVector form an arralist of PVectors (using data parsing; arraylist to cast the individual x,y,z components into PVector format). In void draw() thePVectors are displayed:

 

^{for(int i = 0; i < pointList.size(); ++i)   {            
    pushMatrix();
    PVector vec3D = (PVector) pointList.get(i);
    translate(vec3D.x,vec3D.y,vec3D.z);
    box(10);
    popMatrix();}

 

How do I tell Pocessing to randomly select a PVector from this arraylist? Problem with random is that it returns a float function. Java Random() class doesn't seem to work with the arraylist. The best I can get to is:

 

 int randVec = (int)random(pointList.size());

 

which selects the sequence number of the PVector in the list but doesn't cast the x,y,z components of the PVector. How do I go from here?
