Recommended Posts

1) Where is a quaternion camera tutorial and 2) why are quaternion better then just using radions? (if thats what they replace in a normal camera)

radians are measures of an angle, like degrees. quaternions replace euler angles and matrices for determining rotational orientation. look in the Articles & Resources section of this site probably in the Math section (but maybe physics or some other category). there are links to several quaternion tutorials/ ah, and they are "better" than euler angles because they do not suffer from gimabl lock ( the symptoms of gimbal lock are a sudden flipping about one axis, but you can google for more info ).

Don't beat yourself up trying to learn all about them at first. I still only have a general understanding of them and use them quite extensively. I would suggest learning how to rotate and apply them to matrices. Learn axis-rotations, or rather, learn how to perform an axis-rotation. Like many other things, I believe they will make themselves clear after you begin to need more and more functions in your rotations.

They are a pretty advanced math topic.

I mean like inside your profile is the article listed in one of your posts or something?


No, it's an article I submitted to gamedev.net some time back, called "A Simple Quaternion Based Camera". It's listed in my profile.

EDIT: You're right, it seems they've taken the submissions out of our personal profile. Damnit, I guess I'll go dig it up for you then. Gimme a minute.
