How to rotate OBJ around specific point always?
I previously asked this question and I was told to translate, rotate, then translate back. After many hours of debugging trying to understand what was going wrong, I have come to the conclusion that it doesn't work like that. When one rotates using GlStateManager.rotate, all the axes of the OBJ rotate as well. In other words, the final translation will translate in reference to the rotated axis, making it impossible to translate to it's previous position. For example:
// Move in the x
This is the definition of matrices. Understanding matrices will definitely help you solve this. I recommend watching this:
Linear transformations and matrices | Essence of linear algebra, chapter 3*
As for how to rotate around an axis, in 3D, you can look at how utility method is implemented in JOML:

This is generic use case, but now i have to correc
