Negroponte: "It's not subtle. When you see > it, you gasp." He's right. Characters on the screen look just beautiful, [... lots of interesting experimental results deleted ...] Hear! hear! I can attest to the beauty of fuzzy fonts. In 1980 or 1981 I went to see some spiffy interactive software demonstrated at the MIT AI lab. The software was great, but we all wanted to know HOW THEY GOT THOSE WONDERFUL FONTS! (They called them anti-aliased fonts, not `fuzzy'; guess the term is more recent.) They were so clear that they truly seemed to float just off the surface of the monitor. One point not mentioned in the above articles is that one of the reasons fuzzy fonts work is that they actually *increase* sharpness AS PRESENTED BY A CRT. This is because, in typical, aliased, fonts, the abrupt transition from 0 to 1 induces ringing in the electronics, showing as bluring at the pixel edge. By allowing a gradual step to full intensity in the right places, fuzzy fonts generate a much clearer perceived edge. -- Bill UUCP: {husc6,cmcl2,mit-eddie}!harvard!cfa!wyatt Wyatt ARPA: wyatt@cfa.harvard.edu (or) wyatt%cfa@harvard.harvard.edu BITNET: wyatt@cfa2 SPAN: cfairt::wyatt
