geo/SDFRound

Rounds off an SDF object, or erodes it.

Sdf Operations

Pushes each input SDF object's surface outward by `radius`, which rounds off every convex edge and corner. A negative radius pulls the surface inward instead, which shrinks the shape and rounds off its concave features. It works on 2D and 3D fields alike: rounding a geo/SDFSegment2D is how that zero-area segment becomes a 2D capsule. Non-SDF objects pass through unchanged.

Parameters

Name Type What it does
radius Float How far the surface moves out. Negative erodes instead.
