I was just wondering if APP's spherical projection is what cubicconverter calls equirectangular?
spherical projection = equirectangular
The meaning of the word "equirectangular" is (roughly): a rectangle having a given area in the subject is rendered as "something" having a constant area in the image (this area don't depend of the rectangle location in the subject provided it's at a given distance of the camera.)
I'm so excited by APP that I'm buying a new lens for my 350d. I was wondering if anyone could advise me whether the really wide 10-22mm canon lens would be a good decision (for 360 qtvr's) or if I should get the 8mm sigma fisheye and wait until APP has fisheye support?
It depends ...of the subjects you want to shot:
- Using 10-22mm Canon lens lens you will need a minimum of 12 images to cover the 360°x180° sphere and will get a resulting pano of 11600 x 5800 pixels. This could be fine for landscape and other still subjects.
- Using Sigma 8mm f/4 EX DG Circular Fisheye you will need a minimum of only 3 images but will get a lower image definition. A low image number is very useful for subjects where many moving people, cars, etc are found.
