The assignment for tdc576 is “Make a 360deg panoramic photo of a room in your house.” I did not use an app, and found out late in the process that my Motorola Photon Android phone has a panoramic mode for the camera. I set up my Nikon D3200 dSLR on a tripod in my home office and just took several (11) pictures, rotating the camera after each, and leaving the focus and exposure on automatic. Each image is about 1.6 MB. After loading them onto the computer, I used GIMP to open the images as layers. I scaled the layers down to a more useful size (300 pixels tall instead of 3000). Then I changed the canvas size to have enough room for the eleven images (451 pixels x 11 = 4961 pixels). Then I simply moved each layer over to its correct spot in sequence, merging down onto the previous (accumulated) layer each time. In the end, there was some space left over (so I didn’t need to be so exact in the canvas size, but it helped to guide my placement), so I fit the canvas size to the layer size. The individual images did not line up perfectly, so there is an irregular white space along the top and bottom of the final image. But, for an essentially cut ‘n’ paste job as one might do with paper and scissors, I think it turned out ok. The final step was to export it as a jpg. The final size was only 455 kB. You will need to zoom in to see much detail.
