v1.7.7 — cookbook: Gordon surfaces
Documentation-only release. No code, API, or xcframework change — SPM consumers get the same v1.7.1 binary; only the tag and docs advance.
New cookbook page on Gordon surfaces (#229) — skinning a surface through a network of crossing profile + guide curves via Surface.gordon / Surface.gordonReport (GeomFill_Gordon):
- The grid-closure requirement (≥2 profiles × ≥2 guides, shared corners) and
surface.toFace(). - Build diagnostics —
gordonReportreturns status +isApproximateinstead of barenil;allowApproximateFallbackfor a sampled fallback. - The lower-level
networkSurface(GeomFill_NetworkSurface) and its knot-alignment caveat. - A Gordon-vs-loft-vs-fill decision table.
Snippets compile-checked; figure rendered from the same network the page shows.
The cookbook now spans ten pages: Booleans · Threads · Helices · Lofting & Sweeps · Helical Sweeps · Healing & Validity · Meshing & Export · XCAF Assemblies · Topology Graph · Gordon Surfaces.
