thank you very much for this video you explained it so well <3. Anyone with more than 3 braincells can understand this, unfortunately I'm not one of them.
4 months ago I ask my senior, "What is Quaternion stand for? How do I use or understand these stuff" he said you better not, just ask for the result. . Today I just found this video, I'm not regret, it just a bit overwhelm. And yea my head is dead. 😂
