Spherize filter options

Presets, Preview, Split view
[Nota] Nota

These options are described in Seção 2, “Common Features”.

Modo
  • 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 Interpolação.

Use the selection as input, Use the entire layer as input

These options are common to GEGL-based filters. Please refer to Seção 2, “Common Features”.

5.10.4. 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.
