3D Printing On A Much Larger Scale

March 15, 2010 by Mike Szczys 44 Comments

The end goal of this giant rapid prototyping machine is to print buildings. We’re not holding our breath for a brand new Flintstones-esque abode, but their whimsical suggesting of printed buildings on the moon seems like science fiction with potential. The machine operates similar to a RepRap but instead of plastic parts, it prints stone by binding sand with epoxy. This method is not revolutionary, but hasn’t really been seen in applications larger than a square meter or so. It’s fun to see the things we dabble in heading for industrial production applications.

Home Cinema 3D (or Just Tick Off Theatergoers)

March 4, 2010 by Jakob Griffith 55 Comments

After a visit to the local theater and discovering the use of IR 3D glasses (for films such as Avatar), the team over at Furrtek wondered how they worked, and more importantly, how the glasses could be manipulated to tick off audience members. While the original intentions seem a bit childish, they did mention that their final setup could also be used for a home cinema with IR 3D glasses.

Onto the good stuff: the glasses receive IR light pulses timed with the movie to black out the appropriate eye with the appropriate frame and producing a 3D effect. With the use of IR Investigator the team grabbed said timings; it was then simply a matter of building their own IR projector, and bringing it back to the theater to annoy the crowd setting it up for their 3D home cinema.

Fujifilm 3D Camera

January 10, 2010 by James Munns 22 Comments

There have been a couple companies that have shown off full-sized 3D displays, but Fujifilm had a couple of products that caught my eye. The first was a stereoscopic camera called the Finepix Real 3D W1 that not only functioned as a 3D Camera, but also featured a glasses-free 3D display on the back. The camera was capable of using the separate cameras in different functions, allowing you to zoom one in, and take a wide angle with the other simultaneously.

They featured a miniature 3D display as well, which was the size of a regular digital photo frame but contained the same technology as the camera screen. As far as getting into hacking a 3D display, this would be a good place to start, though the ~$400 price might be a bit of a put off.

CES: 3d Tv, Without Glasses

We were hoping to get to test drive some of the 3d televisions that don’t need glasses. We had speculated about how they worked, and we were mostly right. It appears to be some type of lens that works similar to those little printed holograms. The strange thing is that we haven’t seen any of these TVs in the big name booths. The few that we have seen are in little booths at the edges. The big names are usually doing the polarized glasses or shutter glasses.

“it was nice not wearing glasses”… yeah, I know, I’m wearing glasses.

Update: Realtime 3D For You Too!

December 30, 2009 by Mike Szczys 25 Comments

[Kyle McDonald] has kept himself busy working on 3D scanning in realtime. He’s posted a writeup that takes us through the concepts, tools, and assembly of a DIY 3d scanning camera. You should remember a preview of this method posted earlier this month, but now it’s time to build your own. You’ll need a camera, a projector, and some open source software to process the image data. Using these simple tools, [Kyle] turned out much better video than before. Take a look after the break to see his results from scanning at 60 fps using a PS3 Eye. The trick to this setup is getting the correct synchronization between the projector and the camera, something that could be improved with a bit of extra hacking.

Does [Kyle’s] name sound familiar? It should, he’s got a long history of quality hacks that we’ve featured over the years. If you’re looking to use a scanner as a multitouch, add some music to tea time, or play with your skittles his work will give you a shove in the right direction.

Scan Room, Explore Virtually

December 16, 2009 by Caleb Kraft 6 Comments

[Patrick] directed us to his project for alternate realism. The final goal is to be able to walk around in a space wearing a head mounted display, exploring a virtual representation of that space. This virtual representation could be altered, stylized, augmented and modified in countless ways. It is an exploration in perception, similar to enjoying different styles of painting, we could enjoy different styles of viewing a real space. Currently, it isn’t quite real time. He has to scan a room with a somewhat bulky device, then plug into his display to explore it. Being able to scan quickly and reliably enough shouldn’t be far off. [Patrick] notes that others have done almost real time scans at home already.

Make Your Own 3d Monitor

Don’t let this cruddy video fool you. [Sprite_tm] has done an amazing job here. He has put together a fairly simple way of creating your own 3d monitor at home. The basic principle is easy to get. You have to supply different angles of an object, on the screen, at the same time. [Sprite_tm] has done this by using transparency sheets, printed with a pattern to only show specific pixels. As you move your head, you see a different set of pixels, and therefore a different image. It’s simple, but it works. The system isn’t really new. Traditional 3d with polarized glasses uses a very similar setup. This system however seems like it is lacking in stereoscopic view however. When you move your head, you’re looking at a different angle, but still a 2d image of it. It would be really cool if he could somehow present each eye a different view, without polarizing filters and glasses. We’ve seen others do that with multiple screens, but that gets so clunky and can give most people a headache pretty quick. We also think we are about to see a flood of face tracking perspective modification, especially with project Natal and similar technology emerging.
