Opengl fisheye projection
WebThis work presents an image-based approach to efficiently generate multiple non-planar projections of arbitrary 3D scenes in real-time. The creation of projections such as panorama or fisheye views has manifold applications, e.g., in geovirtual environments and in augmented reality. http://paulbourke.net/dome/domegeom/

WebFisheye projection doesn't have this problem. See this comparison chart to see why: one of the most stunning conclusions you can draw from it is that, if you're used to playing with fov 120, you essential get fov 180 fisheye for "free", as objects in the middle of your screen (what you aim at) are the same size still (!)
