Hey guys,
\n\nAs you know, this competition involves a lot of 3D rotations using Quaternions. \nHere are some resources which I found very helpful, you might wanna take a look:
\n\nVideos on YouTube:\nFantastic Quaternions - Numberphile\nVisualizing quaternions (4d numbers) with stereographic projection\nQuaternions and 3d rotation, explained interactively
\n\nDo NOT forget to checkout this website:
\n\n\n\nThanks to Grant Sanderson and Ben Eater
\n\nP.S: I think I've kinda understood how we are using quaternions in this competitions, do let me know if you have doubts related to them, I'll try my best to help :)
