The To Sphere transformation will give the selection spherical qualities. The Fig. Monkey with increasing sphericity. below shows the results of applying the To Sphere transformation to the monkey mesh.

Monkey with increasing sphericity.

The sequence above shows a monkey mesh with a 0, 0.25 (25%), 0.5 (50%) and 1 (100%) To Sphere transform applied.

Usage

To Sphere Factor.

Select the elements you want to operate on and activate the To Sphere transform tool. The To Sphere tool can be invoked from the Mesh ‣ Transform ‣ To Sphere menu or by pressing Shift-Alt-S. The amount of sphericity given to the selection can be determined interactively by moving the mouse or by typing a number between 0 and 1. Pressing Return will confirm the transformation. The confirmed transformation can be further edited by pressing F6 or by going into the Tool Shelf and altering the Factor slider provided that no other actions take place between the To Sphere transform confirmation and accessing the slider.

Note that the result of the To Sphere transform is also dependent on the number of selected mesh elements (vertices, faces, etc.). As can be seen in the below image, the result will be smoother and more spherical when there are more mesh elements available to work with.

To Sphere applied to cubes with different subdivision levels.

In this image sequence, To Sphere was applied to the entire cube at levels of 0, 0.25 (25%), 0.5 (50%) and 1 (100%) respectively.

The To Sphere transform will generate different results depending on the number and arrangement of elements that were selected (as shown by the below image).
