Taking a break from working on emmap, I got back into the wonderful of C/OpenGL/SDL programming again.
SDL is a wonderful library that does... well a lot, but in a portable fashion that works on many platforms. One of these include Full Screen Anti Aliasing (FSAA), which makes things Look Good. I won't go into detail on how its done via SDL, there are resources a plenty. What I will impart is however a small piece of knowledge I gained after debugging a visualisation I am writing: FSAA through SDL will only work reliably cross platform only if the screen color depth is 24 or less.
Its a small thing, but it took a while to work out. Hope this helps some one :-)
Cheers,
Steve
