[Algorithms] Left-handed vs. right-handed

[Eric H. <eri...@gm...>]

I've written up my way of thinking about left-handed and right-handed world
and viewing systems. It's a bit long-winded, but here it is:

This topic is in one sense basic stuff, but it leads to so much confusion.
Neither DirectX nor OpenGL does a good job of dealing with this confusion,
IMO. In our book we kind of sidestep the whole issue (choose RH, stay RH).
I'd love to get any feedback and corrections from people on this list
(either here on the list, via private email, or on the blog), as I expect
there are ways of thinking about it I hadn't even considered or have
misinterpreted.
