The Argument for True 3D
Today I was doing a little work around Zebra HQ in preparation for the vBusiness Expo, and I came across an interesting problem.
Take a look at this picture. There’s me standing next to a tree.
Oh, but wait… that tree isn’t even on the ground!
As it turns out many of the trees around the island have been like this for months and I didn’t realize it until I took a little stroll through them. For the first time ever I can see the need for stereoscopic glasses for home use, because had this been in real life I’d have been able to tell right away that the tree was floating…
well… except in real life trees don’t float…
you know what I’m going to just go ahead and hit “Publish” on this thing without thinking too hard about what I’ve just said. What the heck. Here I go.
Yes, common “error.” Comes from not using the camera to inspect everything from all angles by rotating the camera around it.
The other common error is misjudging distance between objects. The 3D is (obviously) an illusion created by overlapping images — everything is actually on a flat screen. If you don’t look at things from all angles (again, rotate rotate!) things that look together on your screen can actually be far apart from another angle.
