I keep seeing all these examples with gluPerspective, and I'm reading about gluPerspective, and that it is for 3d rendering (whereas ortho is for 2d rendering), but I can't seem to find the method anywhere. I've looked in a dozen places, including under GL., i've tried to find Glu, etc... and I can't find it. did OpenTK change how that works, or how to call it?
i saw something about setting up a frustrum or something... is that what it has switched to?
I'm ok on a 2d setting now for setting up the window but i'm having a heck of a time getting started on the 3d perspective.
one last question, does OpenTK default as a left handed or right handed coordinate system? (i prefer for it to be left handed)
