I was going through the link where NYTimes compared the Nepal before earthquake and after earthquake. Can anyone tell apart from photostiching/panorama and internet browser technology, What different different technologies have been used in creating this?
How can I learn about creating such stuff?
pannellum may be what you looking for. Created by Matthew using CSS or WebGL if supported for panorama visualisation.
I contributed some code and used it for example at my personal site.
A friend of mine is photographer and able to create the photos. You need someone to provide a true cubic/spheric or other panorama. There are several free ones for testing in the web. If you don't find something, I could provide you some test data. For stitching you can use open source Hugin which is utilised by pannellum as well.
To answer short: - photographer & camera + special tripod + ca. 1h time - stiching software like Hugin to create a 2D Panorama source of six or more single images + capture one/photoshop/gimp + 1 - 5 h for retouching - a viewing engine like pannellum or you can use 360° plugin for jQuery or similar to display that content
