This is the Matterport system, and it debuts today at $4,500, or about the cost of a professional digital camera like the Canon 5D Mark III and a nice lens. The necessary access to the cloud platform runs an extra $50-$150 a month, depending on usage.

This is a tool for professionals. But so were the original lug-about laptops or those cell phones shaped like bricks. In the next few years, Matterport's CEO Bill Brown told me, every picture you take will have a three-dimensional component.

"The company started with the long-term vision that there is going to be a 3D sensor in everyone's pocket," Brown said. "We know that we're going to get there ... We think it's as big as the transition from film to digital."

Brown's been working on 3D imaging since his days at Canesta, which created the technology that eventually came to power the latest-generation of Microsoft's Kinect controller.

Along with the co-founders of Matterport, Matt Bell and Dave Gausebeck, he's obsessed with the idea that you'll have a 3D camera in your mobile device soon.

They've even had a chance to play with Google's early incarnation of that vision, the mysterious Project Tango, which purports to create simple 3D maps of a space with sensors embedded in the phone. "These sensors allow the phone to make over a quarter million 3D measurements every second, updating its position and orientation in real-time, combining that data into a single 3D model of the space around you," the project site says.

Because Matterport's system is modular, they were able to connect the Tango into their cloud system and capture a decent model of Gausebeck's garage using just the phone.

"Google has pushed the envelope on the technology faster than people thought was possible," Brown said. He pointed out that Intel, too, has been investing in 3D motion sensing, and said that he thought a company would announce a mobile device with 3D imaging built in before the end of the year.

For Brown, it's obvious that people would want 3D imaging built into their phones.

"There is no reason that anyone would take a picture that is just 2D. When you take a shot, you'll capture the 3D data. If nothing else, your 2D shots will be better," he said. "Today you walk and take a video. If you were capturing the 3D data, you're able to reconstruct anything you've walked through. You've created an environment by putting all of the 3D underneath the 2D data."

I will admit that it still feels strange to me. I'm not sure what I would do with a library of 3D models of the places I've been. But the ability to do such a thing in the next few years with a consumer device still floors me.

For now, Brown sees three groups of people who might be interested in Matterport's pro offering: The documenters, the promoters, and the visualizers.
