If you're just passing an up vector to gluLookAt itself, then there's no need to make it perpendicular first.Thomas ten Catehttps://www.blogger.com/profile/02609144861191873031noreply@blogger.comtag:blogger.com,1999:blog-3365890222783870731.post-36988556732338888632010-08-01T15:06:59.331+02:002010-08-01T15:06:59.331+02:00I'm trying to figure out what you mean?

That's what I assumed when I first looked at gluLookAt and I think that is what you are trying to say?Matthew Mitchellhttp://crytekuk.infonoreply@blogger.com
