3D Stereo images are double images, taken at the same time, side by side with a small horizontal distance, like the two eyes. There is a left and a right image, for the left and right eye respectively.
To enable stereo images to be processed correctly, tick Table IV-A24.
Now upload or import the double images like you are used to do with simple - flat - images.
This will result in photos like:
Now, if you go to the Photo Albums -> Album Admin page and edit the album with the stereo photo, you will see a selection box in the right half of the Edit photo information box.
If you now select Left - right stereo image or Right - left stereo image, this is what will happen:
The double image will be converted to so called anaglyph images that will be saved in the .../wp-content/uploads/wppa/stereo/ sub-directory.
There are several images created, because there are various ways to produce anaglyph images.
Currently i have implemented 5 different algorithms and 2 types of stereo glasses.
To make it possible for the visitor to select algorithm and glasstype, you can add the widget
3D Settings or put it in a box on the page with shortcode
To demonstrate the effect, here is the demo slideshow created with shortcode
[wppa type="slide" album="227"][/wppa]:
- If you accidently set a non-3D photo to stereo, and correct this by selecting no stereo image or ready anaglyph, the erroneous stereo images in the .../stere/ subfolder will be deleted automaticly.
- Due to the large amount of memory required for the generation of the stereo images, it may be required to downsize the images during upload/impport. On this site with 128Mb server memory, i downsized to 1920 * 1080 to avoid 'memory exhausted' errors.
- If the creation of the 10 stereo images fails due to server time-out, don't worry, as soon as the visitor needs one that is not created yet, it will be created at that moment.
