The Gimpel3D 2D to 3D Stereo Conversion Software is Now Open Source

November 20th, 2013 · No Comments · 2D to 3D Conversion


I’ve introduced the free Gimpel3D manual 2D to 3D stereo conversion software here on the blog back in 2011, and now the author has made it an open source software by releasing the code of the project on Sourceforge. Gimpel3D is a free application that can help you convert a single 2D image or image sequence into stereoscopic 3D written by René Gimpel. The conversion to 3D is manual and the software only assists you, so do not expect automation like with an 2D to 3D autoconversion solutions that do everything with just a click of a button, with Gimpel3D however you can get much better results.

Since the original freeware release of Gimpel3D, many of the ideas presented in the software have become standard features in commercial software and as a result the author of the program has decided that there is no significant advantage to continue developing it as a stand-alone proprietary solution, although the codebase makes a nice platform for future research and experimentation. René Gimpel has released all source code for G3D under the GPL so that other stereo researchers, hobbyists, and/or professionals can build upon his existing work, and integrate/test new capabilities using the projective modeling environment.

Real or Fake 3D, the New 3D Conversions and 3D Movies for 2014

September 7th, 2013 · 2 Comments · 3D Movies & Videos


Here is a short list of the announced movie titles for release in 2014 and which ones will be shot in 3D and which will be converted to 3D in post production according to the website Real or Fake 3D. The 3D movies released (and to be released) this year that were shot in 3D were more as a number than the ones that were converted to 3D in post, even though some of the most anticipated movies are using 2D to 3D conversion. And so far this trend will seem to continue in 2014 as well, but you should be aware that even if a movie was shot in 3D does not mean that it will be a great one and even if 2D to 3D conversion is used if made well and properly used the movie might end up good. In general however watching stereoscopic 3D movies that were shot in 3D and not converted in post do provide better experience than the ones that have been converted to 3D.

IOGEAR 3D Complete+ 4-Port HDMI Switcher with 2D/3D Video Processor

June 28th, 2012 · 2 Comments · General 3D News

The company IOGEAR is not new to 3D-capable products and more importantly to interesting and innovative such ones, you may remember their wireless 3D video streaming product. Now they’ve just announced another interesting device that centers around a 4-port HDMI switcher with some interesting 3D capabilities as extra. The device called 3D Complete+ comes with a built-in 2D to 3D autoconversion functionality, allowing you to convert pretty much any 2D source with HDMI output into stereoscopic 3D, though mind you it is still an automatic conversion, so it will not be as good as good real stereo 3D content being played back on a 3D-capable display. There isn’t a lot of information regarding the 2D to 3D conversion algorithm being used or what results should you expect, this is something that needs testing, but the interesting thing is that the user has control over not only the strength of the simulated 3D effect, but also on the level of depth and pop-out.

Furthermore the IOGEAR 3D Complete+ features some built-in video enhancement functionality intended to improve the quality of the content you are watching using the device, especially when playing back more seriously compressed video from Internet or and SD video that can be upscaled 480i/p to 720p HD and 720p to FULL HD 1080p). Support for de-interlacing, bad light correction and adaptive sharpening as well as de-blocking and noise reduction are among the built-in video enhancement function available with the device and apparently you have the ability to see a split-screen before and after image with and without the image enhancements active (you can disable them of course). But the extra functionality that doesn’t get that much attention in this device is the ability to output 3D content in “Page Flip” or “Frame Sequential” format intended for use with “3D Ready” (3D DLP) projectors connected as output 3D device. The device itself features HDMI 1.4 support for 3D content and you should be able to feed it with HDMI 1.4 frame packaged content from lets say a Blu-ray 3D player and output the 3D in frame sequential or page flipped format on a 3D DLP projector that does not feature HDMI 1.4 support. This extra functionality makes the IOGEAR 3D Complete+ even more attractive solution for people looking for an adapter to allow them to get HDMI 1.4 support on their earlier 3D-capable DLP projectors that don’t have hardware support for it.

The IOGEAR 3D Complete+ has an MSRP of $199.95 USD and should soon be available. The only problem with this device in particular as well as with all other IOGEAR products is that aside from North America they are not that easy to find elsewhere…
