Opengl fisheye

WebThe following presents one method by which two fisheye images, with sufficient apertures, can be combined to form one spherical (equirectangular) projection. It is one of two main approaches, this is a purely geometric algorithm, the alternative is to detect feature points between the two overlapping fisheye images and perform a warp/blend. Web7 de jun. de 2003 · With REAL fisheye I mean the error that occures on real cameras, you move too near to a plane with a big fov and the plane distorts into a sphere. In current 3D …

I did it like this (not real fisheye, though, but close): 1) calculate static texture coordinates for an NxM grid (64x64 seems suitable) into which you divide your screen, adding a sin/cos component to the calculation - with proper parameter you can create all kinds of distortions. precalulating these values will save ...
