A look at John Carmack and open frameworks: In the Background, a Man in the Gaming Forefront
It is chiefly Mr. Carmack’s programming that has led, over more than a decade, to a series of breakthroughs in the way computers graphically render believable environments and characters. He has been largely responsible for making those characters appear to move convincingly through three-dimensional space while interacting with much of what they encounter.
Without his innovations, many say, it is difficult to imagine how a pioneering first-person-shooter game like Id’s Wolfenstein 3D, released in the spring of 1991, would have looked or played.
He is also credited with helping to pave the way for popular multiplayer gaming and with unlocking his programming for players, enabling them to modify the games’ look and feel.
