  | Note
  These options are described in Section 2, “Common Features”.

Mode

  - Radial is the default mode. See example above.

  - Horizontal: as if image was mapped on a vertical cylinder.

  - 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 Interpolation.

#### 5.12.4. Using Spherize filter

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.
