Detailed Description

Rounding operator.

Adds an offset to the argument scalar field. When applied to Euclidean signed distance functions, it produces a rounded shape defined as the Minkowski sum between the object and a sphere.

See also: Specific scalar functions that are signed Euclidiean distance fields.
