Summary

[edit]
Description
Deutsch: Zimmer schräg fotografiert und in die gnomonische Projektion umgerechnet. Der Öffnungswinkel α ist diagonal 109,5° (Superweitwinkel) und orthogonal 90° (eine Fläche einer kubischen Umgebung).
, sind Kugelkoordinaten (Objekt) und , Polarkoordinaten (Bild).


English: Photo of room obliquely taken and remapped into gnomonic projection. The field of view (fov) α is diagonal 109.5° (ultra wide-angle lens) and orthogonal 90° (a face of a cubical environment).
, are spherical coordinates (object) and , polar coordinates (image).

You can crop lossless with JPEGTRAN or JPEGCROP. The parameter format is WIDTHxHEIGHT+LEFT+TOP.

Warning: The source image area does not have enough pixels, so this image may be blurred. The optimal image size would be 2000×2000 with f scaled to 1000.
