Plucker coords considered harmful

Christer Ericson has a terrific article on why scaler triple products are usually preferable to plucker coords here. I couldn't agree more. Christer has a book on collision detection I have been meaning to order for sometime and his blog content encourages me.

I never really understood all the fuss about Plucker coords. I always went on with basic 3D linear algebra when it came to lines and rays. As it was (a) something you can have an inherent understand of without needing to twist your brain into 6D space, and (b) simple and efficient enough, for not wanting to complicate things beyond that unnecessary.

So I'm glad some of the big guys agree =)
