3D/VR Stereo Photo Viewer

New Version 2 Supports 360 3D Panorama Photos and Swivel VR!

Turn your phone into a dynamic stereoscope with zoom capability!

The 3D/VR Stereo Photo Viewer app lets you quickly and easily view your 3D stereo photos stored on your phone or found in Web pages. With a Cardboard VR viewer or a stereoscope, you can zoom into your 3D photos and see all the detail in stereo. And since your phone display size may nearly match your eye separation, you may be able to "free view" stereo photos without a stereoscope or Cardboard VR viewer.

The 3D/VR Stereo Photo Viewer displays side-by-side (stereoscopic parallel MPO, JPS, JPG or PNG) photos. It also displays individual filename suffixed _L and _R photos in stereo. You can access stereo photos on the Web with URL links pointing to galleries or individual photos. The app loads Web photos from a QR code URL link, a clipboard URL link, or a server URL link stored in a menu Settings option. My recommendation for a free QR code reader is the "Barcode Scanner" app by the ZXing Team. Generate QR codes on my notebook computer while viewing Web sites to let you view all the photos on a Web page in the app.

You can swap left and right photos using a Settings option or remote bluetooth key controller. Remote controller keys provide many convenience features.

Capture 3D photos using the Camera Cha-Cha technique function launched from the menu, or volume up button. You select the camera. My recommendation is the free "Open Camera" app by Mark Harmon.

The app displays stereo photos intended for viewing with Google Cardboard type stereoscopic viewers, a smartphone stereoscope, such as a Lorgnette stereoscope, or the Cyclopital3d View-Vaster stereoscope. Enter the Cardboard VR viewing mode with menu option or configurable long press on the screen and insert your phone into the viewer.

With a Cardboard VR viewer you can zoom in and out of a stereo photo by rolling the viewer right (zoom-in) or left (zoom-out). With the zoom feature you can see more detail in high resolution photos on a smaller resolution screen and by zooming out you can see foreground subjects with more comfort.

In VR mode photos up to 6K (6144) pixels per side will display without downscaling the image. The viewer only resamples/scales photos with a total size larger than the product of 6144 by 6144 pixels or any side greater than 8192 pixels. You will see the best zoomed 3D stereo photo only when you view MPO or individual left/right eye photo files with _l and _r suffix. The phone must have enough heap RAM memory, 512MB, which is available with Samsung Galaxy S6 or S7 phones, for example.

To re-position the image with the viewer look up/down (pitch), or left/right (yaw) slightly to begin movement, and then stop movement by returning your headset to its original position. This will move the photo in a window to show areas of interest. The headset move technique is named "couch viewing" because you can recline on a couch and view photos that will stay in position. The Zoom feature can be disabled in the Settings menu or in Cardboard VR mode with the volume up key. Zoom and photo movement may also be controlled by a mouse in VR mode.

When the distance between the left and right eye image on your phone, center to center, nearly matches the distance between your eyes (i.e. your horizontal phone display width approximates the width of your glasses), it may be possible for you to "free view" the photo to see it in 3D stereo without a stereoscope or other viewer. In VR mode you can free view zoomed images too. To learn more about the free viewing technique, do a Google search "how to free view stereo (3d) images". In Settings, turn off lens distortion correction when VR free viewing. DO NOT free view or use this app, if it gives you eye strain or discomfort.
