OCCTSwiftMesh API Reference

A detailed, per-type function reference for the OCCTSwiftMesh Swift API. One page per public type, every public symbol documented: signature, behaviour, parameters, return value, and a runnable example.

This complements the other docs — it’s the exhaustive surface, vs:

• guides/cookbook/ — task-oriented example pages.
• algorithms/decimation.md — the QEM backend deep dive.

OCCTSwiftMesh adds its public surface as extensions on OCCTSwift.Mesh (the triangle-soup value type, re-exported via import OCCTSwiftMesh) plus the value types each algorithm returns. There is no free-standing API beyond the OCCTSwiftMesh namespace marker.

Types

• OCCTSwiftMesh — the module namespace marker (version constant).
• Mesh+Simplify — the Mesh.simplified(_:) decimation entry point.
• SimplifyOptions — Mesh.SimplifyOptions, the decimation inputs.
• SimplifiedMesh — the decimation result (mesh + before/after counts + Hausdorff distance).
• Cross-Section Types — CutPlane, MeshContour, MeshCrossSection, and the Mesh.crossSection(plane:) / Mesh.crossSections(axis:through:spacing:) slicing entry points.
