3D Coding on the Z-axis

Processing Coding Questions
1

Hi all!
Phil here again, as you know this has been a very stressful year, so I thought coding would be a fantastic way to get back my mojo in self-isolation! For those of you who are unaware, I began to learn coding last year and I have loved every minute of it! I was inspired to code when my namesake, Punxsutawney Phil, the groundhog on groundhogs day said that we would have a long winter…brr… Anyway, it seems that I am in a bit of pickle as I have expanded my coding repertoire into the 3D world, an exciting new endeavor! I am having some trouble with coding 3D shapes that rotate on the Z axis and I would love any trips, tricks, or code that might be helpful.
Thank you all
Warmest regards,
Phil Random

here is an example

what is your specific question?

Chrisir




float angle1; 

void setup() {
  // init
  size(800, 600, P3D);
} // func 

void draw() {
  // runs on and on 
  background(0);
  lights();

  stroke(100); 
  //  noFill();
  fill(255, 0, 0);

  pushMatrix();
  translate(100, 100, 0);
  rotateZ(angle1);
  angle1+=.04; 
  box(60);
  popMatrix();

  pushMatrix();
  translate(400, 100, 0); 
  rotateX(angle1);
  fill(0, 0, 255);
  box(60);
  popMatrix();

  pushMatrix();
  translate(700, 100, 0);
  rotateY(angle1);
  box(60);
  popMatrix();

  pushMatrix();
  translate(700, 300, -330);
  noStroke(); 
  sphere(50);
  popMatrix();
} // func

Also don’t forget the PeasyCam library, if you want to rotate something that is centered and look at it.
