What the heck are quaternians? Defining rotations in 3D space is complex. You need to express the rotation axis vector and how much you want to rotate around it. That's where quaternians come into play. These are four-dimensional objects where the first expresses the rotational amount and the other three express the rotation axis vector. Why math libraries use these so much? That's because they're both accurate and compact.

Thou you know,
