Crate brepkit_offset 

brepkit-offset

Solid offset engine for brepkit.

This is layer L2, depending on brepkit-math, brepkit-topology, and brepkit-geometry.

Pipeline

The offset algorithm follows a 9-phase pipeline:

1. Analyse — classify edges as convex/concave/tangent, derive vertex classes.
2. Offset — construct the offset surface for each face (translate planes, adjust cylinder radii, etc.).
3. Intersect 3D — intersect adjacent offset faces in 3D to find new edge curves.
4. Intersect 2D — intersect offset PCurves in parameter space to find edge split points.
5. Split edges — split original edges at intersection parameters.
6. Arc joints — optionally insert rolling-ball arc fillets at convex edges.
7. Build loops — assemble trimmed edges into closed wire loops for each offset face.
8. Assemble — build the final shell and solid from offset faces and wire loops.
9. Self-intersection removal — detect and excise global self-intersections if enabled.
