Vertical: as if image was mapped on a horizontal cylinder.

Angle of view

Camera angle of view (0 - 180°)

Curvature

Spherical cap angle, as a fraction of the co-angle (complement angle) of view. Result is less domed as curvature decreases (100% - 0).

Amount

Interesting for negative values, which result in a hollow instead of a bump (from 1.000 to -1.000).

Resampling methods

These interpolation methods are described in Interpolaatio.
