When programming games, it is mandatory to know something about vectors. They are neat, and well represent... Wait, what do they represent?
Yeah, my problem is that I have come across vectors called forward, left/right and up. As far as I know, these 3 vectors were put to use in at least one commercially successful video game franchise, Ratchet And Clank:
In the video, two game developers, who worked on Ratchet And Clank: Up Your Arsenal, talk about problems they were having with vectors on spherical worlds. Very interesting, but difficult for me to internalize.
What do these 3 vectors represents and how could one put them to use?
