pub fn fillet_polygon_corner(
ring: &[Point2],
corner: usize,
radius: Scalar,
depth: Scalar,
) -> GeomResult<ExactBRep>Expand description
Fillet one corner of an arbitrary closed polygon profile.
§Why this exists next to fillet_extruded_profile
The profile-based entry point takes a Profile::Rectangle and so can
only ever round a four-corner box. This one takes the ring directly, so
an L-shape, a hexagon, or any polygon a boolean produced can be
filleted. Corners are addressed by index into ring, which is stable
under a rebuild in a way an arena id is not.
§What is still refused
- A radius whose setback does not fit on either adjacent edge. Trimming past a neighbouring corner would silently delete that corner.
- A degenerate corner: collinear or folded edges have no bisector.
- A reflex corner. The blend there is a fillet on the outside of the material, which is a different surface and is not derived here.
