This is Bob. No, I -- well, there is a significant, I would say, a significant shift. 2D is extremely important and can handle most vision problems, but there is additional investment going on. Certainly at Cognex, it's a focus of our top R&D team right now. And a lot of engineers working on what we call displacement sensor to make it -- to distinguish it from our regular Vision Systems and 2D sensors. We are not the first into that area. And many times in our history, we have not been first. We like to think of ourselves as fast followers, which means we get technology, we develop a lot of it, keep it on the shelf until someone else perhaps verifies the existence of a profitable business. Because there are just so many opportunities for machine vision and for image processing, image analysis. But not -- but very few of them are profitable. So we like to say that we're a fast follower and we've done that many times. We were not the first with products like In-Sight, but we followed fast and took over the business, and we expect to do the same thing with displacement sensing. And displacement sensing, by the way, is not only valuable on the factory floor where they're putting assemblies together to make sure that all of the parts are in the right place and they're at the right height, et cetera. But it also turns out to be very important in logistics, where the height of something helps you determine where the box is and where the label is. So we are finding that our investment in 3D, although not yet paying off, we expect that to grow rather substantially in the coming short term. So I would say that we don't see many other companies investing in 3D. It's very complex, 3D, getting that third dimension, is very, very complex, and depending on the accuracies and the field of view that you want and the depth of field. And it's going to be companies like Cognex, and of course, some of our competitors have -- 1 or 2 of them have 3D products, that we will soon surpass on a technological basis.
