Dear Ptereo,
A great site!! Thanks for this initiative! And I see a good interpretation of the stereo viewing methods! A very first indeed!!! Most of the other programs/sites don't fully recognise 'parallel' and 'crossed' properly. Of course for that one needs to provide the right parameters when uploading pictures (to make sure that the viewing method is also correct), and I have the idea that is properly implemented in the 'Import' choice one has in the Phereoshop program. Well done! So great knowledge was put into this (and even under some stereo enthiosiaist this knowledge is mostly not consistently implemented in program/websites). This will make your place a good and future proof stereo web site!
I though have one additional request.
When in parallel mode, I would like to have the stereo picture size not larger than 2 times the distance bewteen the eyes (say around 12cm). With parallel viewing one can't have each picture larger than around 6 cm (some say 6.2cm), if larger one would need a tool (like special reading glasses). As you know, crossed viewing does not have this issues, but some people can't cross view...
I think with tablets this 12cm (2*6cm) is easy to determine, as one can read from the device/display the number of pixels per inch. For deskops/laptops this might be more difficult, but not sure as I think it is now possible in modern screen drivers (I made a web interface [based on javascript] to let the user input this data: http://www.iol.ie/~geniet/3d/calibration.htm [it needs no blocking of pop-up windows, I know a little clumsy])...
At this moment I can't use the parallel option you provide, as the pictures on my laptop (Dell XPS) are always some 19 cm. Also if I make my browser window smaller, the displayed size of the stereo picture is not effected, while that could be another, less user friendly, solution.
Can you help in this feature request? Thanks for considering.
All the best,
Victor
