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. |
