thankyou for your interest in our opengl product line. your formality has been noted, and we can recommend you chill out. relllaaaaaxx. ))
it depends on what you mean by “supporting” it. if your card supports the accumulation buffer, then you have to do antialiasing manually. (I guess you mean antialiasing, since all cards can alias to their hearts content By “manually” i mean you have to explicitly redraw the scene with subpixel camera offsets. (Opengl will take care of blending them together for you, tho’)
if you card is really cool, then it might be able to do antialiasing by.,… well, a couple of reasons. having an increased virtual resolution is one of them, but a slightly different tack it to create “buckets” within a pixel. they’re effectively the same sort of thing, tho’, and it’s transparent to the prorgammer. in this instance, you’d give opengl the hint to make polygons etc look “nice”. and cross your fingers
hope this helped!
