Hello gents! (and ladies)
I’m in the process of implementing my own gluLookAt function, and I need some clarification on the notation used on this page: http://pyopengl.sourceforge.net/documentation/manual/gluLookAt.3G.html
Specifically, the line that states: Finally, let s = f × UP ’ , and u = s × f. The small x denotes a cross product, correct?
