Does anyone know how to code this? I followed the algorithms from the following link: http://astronomy.swin.edu.au/~pbourke/projection/fisheye/ I can see my fisheye view but my image is too distorted, can anyone help please?

Or perhaps the camera should go in the center of the lens. I haven't tried the fish-eye lens thing myself, I've just read about it, so I don't really know. I guess you could try adjusting the shape and position of the lens.
