Subject: Fixed camera positioning, fixed lighting, added arrow points, and more
X-Git-Url: https://git.ucc.asn.au/?a=commitdiff_plain;h=45d3d32957a9172077e05ab344c5607bde87447c;p=atyndall%2Fcits2231.git

Fixed camera positioning, fixed lighting, added arrow points, and more
* Camera code was completely redone so that it is in redraw only
* Starting camera position is much nicer now
* We're now using a perspective projection
* Teapot was having its front faces culled because it doesn't obey the right-hand rule; fix put in place for that.
* Mouse now moves and zooms camera in a way that is very similar to sample solution
* The WASD controls of camera can now be zoomed with a factor, which can be increased or decreased by using - or +
* Window resizing works as sample solution doeson one axis, but incorrectly zooms on another
