The opportunity for 3D is much larger than 3D movies and pictures

With our interest in 3D photography and video, we can get stuck on thinking 3D is just

about photography or movies.

But the future of 3D is vastly larger. As 3D monitors and 3D TVs become wide spread – which is likely a few years out yet – consider the impact this could have on line shopping. And especially when glasses-free displays are common on computers, tablets, phones and HDTVs and the use of 3D is no longer a gimmick but the ordinary.

No longer would we expect to look at a little photo on the web site when choosing a product. Instead, we will likely look at a large 3D view or 3D model that we can rotate and examine, almost as if it were in our hands.

True 3D is also coming. Think “Holodeck” at a small scale. I know people working on this type of technology and for now, the goal is desktop sized “Holodeck” perspectives that enable engineers to design parts in their CAD system and then create a view – not just a mapping of 3D to a 2D display (like the image that accompanies this article) – but a volumetric display which you can walk around and see from all sides.

Add in 3D scanning technology – its available off the shelf today from Microsoft and its called Kinect. Use future 3D scanners to capture information about parts and components or the layout of a kitchen that is to be re-modeled. Or to capture a 3D model of yourself to then use in a virtual clothes fitting exercise where 3D modeled clothes are mapped to your body and checked for size, before you purchase online. So much for retail show rooms? And of course, this can all tie in to 3D printing. Or deliver a 3D virtual world to use from our remotely controlled 3D-seeing robot.

Even traditional 3D imaging can provide us with new perspectives. I enjoy shooting macro 3D – which is close ups of small objects in 3D. Because they are so small we have to get our face so close to the subject that we lose 3D depth perspective. But our camera can capture 3D depth at close range and enlarge it for our viewing.

Similarly, what about slow motion 3D? While we are used to seeing 2D slow motion in sports, 3D slow motion may reveal new insights. And then, what about slow motion macro 3D? Now we may be able to see things that we miss entirely today because we cannot see depth at close range, and definitely not in slow motion.

Hyper3DPhone – Android App – links two phones together for stereoscopic 3D photos

Hyper3DPhone – Android Apps on Google Play.

Designed for taking hyperstereoscopic 3D images using two Android phones.

Run the app on both phones (its free). Identify one phone as the left and the other as the right phone and then move the phones apart.

The app communicates over Bluetooth to synchronize taking photos on both phones at the same time, giving you the left image on the left phone and the right image on the right phone.

Comparison of Lumix 3D1 versus Sony TD10 3D Video cameras

The Panasonic Lumix 3D1 is a compact 3D still and video camera while the Sony TD10 is a larger, traditional styled video camera that shoots 3D video and some stills.

Both are described as 1920×1080 3D video resolution; however, due to the way the video is encoded in each camera, the Lumix 3D1 is shooting at 1920×1080 but encoding in the squeezed 960x1080x2 mode. That is, the left and right images are squeezed down and combined into a squished side-by-side video format (this is the same format that is used by the Youtube 3D support). The Sony TD10 (and it successor the TD20) records dual 1920×1080 video and encodes that as two complete 1920×1080 video streams.

The result is that while the Lumix 3D1 looks quite good for an inexpensive, compact consumer 3D camera, the dual 1920x1080p encoding of the Sony TD10 produces a noticeably sharper image.

To view this and see the difference, you need to select the 1080p viewing option in the Youtube player and display in full screen (on a 1920×1080 sized screen!) Even though Youtube is in 960x1080x2 format, starting with the higher resolution of the TD10 results in a better image quality all the way through.

In each pair of clips in the demo video, the 3D1 comes first, then the TD10.
