Peter Kirn at createdigitalmotion.com has written a piece giving an interesting look at DirectX vs OpenGL. Quoted from the article: “A lot of users understandably wonder about the difference between the two APIs. They might be surprised to discover there’s really little practical difference at this point in terms of what end result you get. OpenGL 2/2.1, not OpenGL 3, is roughly equivalent to DirectX 10 as far as supporting flashy new features. Thanks to extensions to the OpenGL spec, in fact, OpenGL developers often get earlier access to functionality than DirectX 10 developers do, or at least get it on more platforms more quickly” wrote Peter Kern.
