Hi, I found this project interesting.
SO, the idea to convert the images into an anaglyph and then upload them as any other images?

Actually, it's the opposite. Currently, 3D images (jps, mpo) are sent as-is and shown as a wide image, with the image for each eye shown side-by-side.
It should be possible to use the HTML5 canvas to split the image in 2 and colourise and merge them to create a 3D picture which can be viewed with anaglyph 3D glasses.
For performance reasons, especially on mobile, it may not be the best thing to do and a PHP solution might be better. That's for potential candidates to find out.

It's quite a small project and could be some sort of warm-up proving that the candidate is capable of working on bigger gsoc projects.
Let me know what you think.

I found a tiny jQuery library which makes it extremely easy to convert a regular image into a 3D anaglyph. .Basic implementation.

Am I on the right track?

Are we aiming for this?

@madhug-nadig - I think that plugin turns any standard JPEG into a 3D anaglyph, but the idea is to only convert stereo JPEG images into 3D anaglyph. So the best thing to do would be to test with 3D jpegs.

@prastut - Yes. Currently Gallery shows 3D images side by side as it doesn't involve any processing, so that can stay as the normal mode, but then users should be able to see the anaglyph by pressing on a button.

So, a button that can change back and fourth between 2D and 3D, yes?

Yes, also, bear in mind when thinking about the UI that not everybody has red/blue glasses, some are yellow/blue ;)

@oparoz I have a problem in uploading the 3D files. Since the 3D files are above 2MB, they can't be uploaded. I tried the following solutions

• Configured the .htaccess file
• Changed the default size of upload_max and post_max in /etc/php5/apache2/php.ini

Still no luck. From the admin view, it says you don't have permission to change the max file size.

@prastut The 2MB limit seems to be very low. For all questions related to configuring ownCloud, I invite you to look for answers on the forum since this has nothing to do with Gallery or this specific task. Make sure to post all information about your setup, config.php, etc.
