How to make my images spin around an ellipse in P3D?

Hey, josephh. It’s nice to see you again here. Hope you are doing well and safe.

Hi again!

@Rindoom

I am not quite sure how to manipulate my image coordinates with this newly added Z-axis?

This is exactly right, I forgot that the image() function doesn’t accept z coordinate argument!

You can refer to this previous thread to see how to display images properly in P3D :

Show Image in P3D space?

I have a P3D window in full screen mode: fullScreen(P3D). I am rotating a 3d model around, and would like to overlay an image over the screen, so that it is always on top of all elements. How can I do this? I’ve tried just image, and it doesn’t work for me.

For the second code, some improvements :

• The part where you load your images :

  img[0] = loadImage("3.jpg");
  img[1] = loadImage("1.jpg");
  img[2] = loadImage("2.jpg");
  img[3] = loadImage("4.jpg");
  img[4] = loadImage("5.jpg");
  

  can be greatly improved by automating it. As you can see, there is a pattern that can be extracted : img[i] = loadImage("i.jpg") with i being 0, 1, 2, 3, 4…

  For this, check out a previous answer I gave about this :

  (Side note, it’s better to name your array of images imgs rather than img because it can be confusing )

  so I thought it will be a good idea to use float time -= Sadly I didn’t make any difference.

  This is because the time variable is never used elsewhere other than the line where you subtract 50.55. Therefore it does nothing

  @Rindoom

  At this point, all of the images are spinning way too fast.

  What drives the movement of the images is relies in this expression :

  sin(angle *i + offset)
  

  If you think about it, the trigonometric functions are oscillating with a period of TWO_PI (the time it takes to go from -1 to 1 and go back and if you go too fast, it’s oscillating very fast.

  Therefore the offset variable is increasing too much, you can try to reduce the amp variable.
