Processing 3: How to keep the axes in their own position?

Question

I'm making a 3D puzzle, where you have to rotate the cubes. The problem is, that whenever a cube rotates, their axes rotate as well. How do I keep the axes in their own position?

I also made a more detailed Stack Overflow post here: https://stackoverflow.com/questions/59973975/processing-3-how-do-i-not-let-the-axes-move-along-with-the-shape

Answer 1

I don't know about Processing 3 specifically but I've worked with some kinds of 3Ds and rotation and axes stuffs so would you like to tell what's the axis you're trying to rotate it about? I mean, is it at the center of the cube? Is it one of the corner? Or somewhere else outside the cube?
