Glimpses Of A 3D Volumetric Display

Custom displays are a lot of fun to look at, but this one is something we’d expect to see at a trade show and not on someone’s kitchen table. [Taha Bintahir] built a 3D volumetric display and is showing it off in the image above using a 3DS file of the Superman logo exported from Autodesk. In the video after the break you can see that the display is a transparent pyramid which allows a viewer to see the 3D object inside from any viewpoint around the display. Since first posting about it he has also added a Kinect to the mix, allowing a user to control the 3D object with body movements.

There’s basically no information about the display hardware on [Taha’s] post so we asked him about it. It works by first taking a 3D model and rendering it from four different camera angles. He’s using a custom designed prism for he display and the initial renderings are distorted to match that prism’s dimension. Those renderings are projected on the prism to give the illusion of a 3D object floating at its center.

We’re hoping to hear more details about how this was designed and what hardware is being used. We’ll post a follow-up if [Taha] shares more information.

Spin Peggy, Get 3D POV

We put a temporary ban on posting POV projects after receiving several LED spheres back in May. But we had to lift the injunction after seeing this superb Volumetric 3D POV display by [Wes Faler] and [Don Smith].

Their creative use of several readily available components adds to the alluring setup; the central elements being just a box fan and Peggy kit from EMSL. The video after the jump doesn’t really do the project justice, but if you missed it at Maker Fair Detroit and can’t make your own it’s the best you’re going to get.
