This program doesn't require that the camera be at the same angle for all pictures. When you setup the project you tell it all the info on your camera (focal length, res size, etc) and it does calculations from there. This was only a test so I don't have a bottom view though I could easily add it later. You don't really want dead on face shots, though you do want each picture to be 90 degrees to the previous one. Basically to calculate where a point is it needs to be marked on two photos. The more points on more photos the more accurate the point location will be (basically it triangulates the points position). The reason it's so hard with this toy is 1. the picture is very low res (you can zoom way in to place points so you aren't working with small pictures) 2. the ship is all one color and hard to see where the edges and corners are.
