 Panorama Tools FAQ : Panorama Tools Basics :
The panorama I get is distorted in a butterfly shape |
| You specified a rectilinear image output with a MUCH too wide hfov (near 180°). Choose a cylindrical or equirectangular panorama type, and you will have a nice panorama. Very roughly speaking "butterfly" distortion in rectilinear projection is proportional to tangent of half hfov angle - actually infinite for hfov=180°. 2001-Jul-26 10:51 address-suppressed | |
