Horizontal: as if image was mapped on a vertical cylinder.
Vertical: as if image was mapped on a horizontal cylinder.
Camera angle of view (0 - 180°)
Spherical cap angle, as a fraction of the co-angle (complement angle) of view. Result is less domed as curvature decreases (100% - 0).
Interesting for negative values, which result in a hollow instead of a bump (from 1.000 to -1.000).
These interpolation methods are described in 插值.
Drawing a selection before applying filter allows you to create another shape, such as a sphere: select Ellipse tool with the Fixed option checked; draw a circle; apply Spherize filter with the Use the selection as input selected. Invert selection and fill it with wanted background.
