Publisher's Note

As most readers will have observed, the September Fifth anniversary issue marked the beginning of a new phase for BYTE. The jump from a 300-page to a 400-page issue means a 33% increase in the material presented to our readers each month.

Because advertisements tend to be more visible than editorial content (especially in a technical journal), some readers may suspect that the larger issues mean merely more ads. But, in fact, the larger issues have approximately one third more editorial content. The new size does create design and manufacturing problems, however. The solution to these problems includes a redesign of the editorial pages of BYTE to make the editorial content easier to find and use. We expect the new format to be implemented early in 1981.

We are confident that the increased editorial content and new format will make BYTE even more of a bargain as well as a more useful tool for our readers. And that, after all, is what it's all about.

In This Issue

p.172 The cover for this issue of BYTE is a still from a 90-minute computer-animated cartoon called The Works. The photo was provided by Dick Lundin and Lance Williams and is constructed from quadric surfaces and polygons, using texture-mapping and normal-perturbation techniques. The background was painted by Paul Xanter - programming credit also goes to Tom Duff and Duane Palyka. A trailer of The Works was shown at SIGGRAPH '80 (page 172), although the film itself may not be finished for another two years.

p.6 A number of the articles for this month's theme were solicited with the help of Jay Nickson and Ken Lodding; their editorial begins on page 6. Both are employed by DEC (Digital Equipment Corporation): Jay is the manager of the human interface program for simplifying man/machine communications, Ken is a senior software engineer whose long-term interests intermix art and computer graphics.
