3D math help
 
This may either sound like a very advanced question, or a stupid one; but has anybody got any idea how to convert quaternion, Euler angles, roll pitch yaw etc to plain xyz degree angles?

well I did this stuff last year in math class, so im a litle rusty on working with a matrix, but here is a website that should help you answer your question

Do you mean in Alice or in general?

EDIT: By xyz angles, would finding the "3d" angle of the tip of the cone be an example?

EDIT 2: I found this nice website with more "down-to-earth" examples and explanations: [url]http://programmedlessons.org/VectorLessons/vectorIndex.html#10[/url]. It's all about 3D computer graphics and the math behind it.

Thanks, I will look at these sites and see if they help.

Good luck with the math concepts. We never covered dot products with vectors yet. =(
