"At some point in the process, we end up with a digital set of three-dimensional data," says Smith.

Sales of digital sets are projected to reach 6.97 million units this year, about a 70 percent increase from 2003.

So the people (and any nonblue objects) appear superimposed on the digital set.

In reality, it would have been better to wait until 1999" to introduce the first digital sets.

But it is doubtful that those improvements alone would be enough to spur anyone to buy a digital set.

Each one of these universal ants would later be randomly distributed throughout the digital set.

The rest of the digital set was filled by a computer-generated crowd.

"We think a digital set with a lower price point would be of interest to intermediate and beginning drummers."

For the digital fast set, it was a perfect night out.

But the new crop of digital sets is less forgiving.
