Enables viewing of 3D-images in various formats.

You can view 3D-images also directly from the web pages (and play slideshow) and by dragging them from other applications.

Supports MPO files, Side by Side, Top/Bottom and interleaved stereo pairs in JPG, JPS, PNG, TIFF, animated GIF files and anaglyphs as source format. Left and Right sides can be in two different files. Classic stereo cards scans are also supported.

You can view stereo pairs in MPO containers produced by Fujifilm Real 3D W3, Nintendo 3DS, HTC smartphones with stereo cameras, Sony cameras with 3D functions and other.

3D viewing is available in several modes including:
• Stereogram for Cross and Parallel viewing methods
• Stereogram for Top/Bottom viewing method with special glasses
• different kinds of Anaglyph mode for Red/Cyan and Green/Magenta glasses
• Left or Right eye only
• Vertical and Horizontal Interlaced modes for 3D monitors with polarized glasses
• 3D TV mode (half Side-by-Side and Over/Under) including 4K screen support
• Convenient special mode for viewing Classic stereo cards
• Special mode for triple Left-Right-Left images that could be found on the web
• Simple Stereo card emulation viewing mode

Excellent for what it does...

It does a great job of showing the image in a 3d viewable format… needs to be able to save the file since the file is clearly already created in order to present it on the screen in the app. If it did that and maybe allowed for editing of depth of 3d etc, then I could see myself giving it five stars.

Parallax Option

Good Program for seeing 3D in multiple styles. I would like to see a modification that lets the user shift each MPO file left or right to tweak the parallax of the Final Picture.

XstereO Player

I just downloaded free XstereO and bought a LG D2342P monitor to view 3d stereo images from my MacBook Pro. This monitor uses horizontal interlace with passive glasses to view 3d. I needed some way to play my 3d stereo image pairs without using Bootcamp or Windows. XstereO Player does exactly what I need most--that is to display 3d side-by-side images interlaced so they can be shown without parallel or cross-eye viewing. It works perfectly, although version 1.0 only can view a single image (one L-R side-by-side pair) at a time. It can open a variety of image formats and display them in 3d using anaglyphs or interlacing. For this monitor to display full-color stereo, it interlaces one image into even horizontal lines superimposed with the other image in the odd horizontal lines. It has a check box to switch between Left/even-Right/odd or Right/even-Left/odd horizontal lines. Future versions could include new features, such as the ability to do a slide show or work with separate left and right images, for example. I give it four stars because it works well. I haven't found any other similar application for Mac. Being a free download from Apple is also important. Thank you Yuri golubinsky and Apple.
