Keep mapped signatures fixed and preserve translated geometry/pixel assertions exactly.
Enforce checked sizes and indices, then update docs and coverage status.
## Objective
Implement Coord/Quat compatibility plus profiles, paths, faces, and linear/circular extrusion.
## Deliverables
- Preserve cuts, hollow, sides, twist, taper, shear, revolutions, radius/skew, face numbering, winding, normals, UVs, and viewer mode.
- Use checked index arithmetic and original tolerances.
- Keep geometry deterministic for identical inputs.
## Validation
- All owned Coord/Quat and extrusion tests pass.
- Every emitted face index is in range and finite-value checks pass.
- Golden mesh summaries match the reference.
## Prerequisite
Types and StructuredData are implemented and the global API/test gates are complete.
## Project constraints
- Native Rust implementation only; optional third-party native codecs stay behind documented features.
- Keep mapped signatures fixed and preserve translated geometry/pixel assertions exactly.
- Enforce checked sizes and indices, then update docs and coverage status.

added this to the 06 - Imaging and PrimMesher implementation milestone 2026-08-08 08:17:26 +00:00
Replaced the failure-only Coord, Quat, UVCoord, Face, ViewerFace, Profile, Path, PathNode, and PrimMesh shells with native Rust ports of the pinned PrimMesher.cs behavior.
cargo fmt, mapping/shim generation checks, API coverage, reviewed test parity, default and all-feature workspace checks, default and all-feature workspace clippy with warnings denied, rustdoc with warnings denied, and package-list verification all pass.
Post-implementation review found no production placeholders, panic paths, or unchecked unwrap/expect calls in the native mesher. Every emitted face is range-checked and every emitted coordinate/normal is checked for finiteness.
Implemented and pushed in commit 5b3950c.
Implementation:
- Replaced the failure-only Coord, Quat, UVCoord, Face, ViewerFace, Profile, Path, PathNode, and PrimMesh shells with native Rust ports of the pinned PrimMesher.cs behavior.
- Implemented special 3/4/24-side profile tables, arbitrary-side cuts, hollow triangulation, cap/side winding, linear/flexible/circular paths, twist, taper, shear, skew, radius, revolutions, normals, UVs, viewer faces, prim-face numbering, copying, transforms, raw output, and viewer indexing.
- Added checked size/index arithmetic, 65,536 profile/path limits, a 16,777,216 mesh-vertex limit, finite-value validation, deterministic construction, and typed errors.
- Updated generated shim coverage, the controlled-suite baseline, the rendering shim smoke test, and README documentation.
Verification:
- 45 owned translated Coord/Quat/PrimMesh tests pass: 8 Coord, 10 Quat, and 27 PrimMesh.
- 4 native tests pass, including box/torus golden summaries, normalized special-profile UVs, deterministic complex circular extrusion, index/finite checks, and hostile-size rejection.
- Controlled workspace audit: 257 passed, 1,155 expected standardized failures, 0 ignored, live credentials enabled.
- cargo fmt, mapping/shim generation checks, API coverage, reviewed test parity, default and all-feature workspace checks, default and all-feature workspace clippy with warnings denied, rustdoc with warnings denied, and package-list verification all pass.
Post-implementation review found no production placeholders, panic paths, or unchecked unwrap/expect calls in the native mesher. Every emitted face is range-checked and every emitted coordinate/normal is checked for finiteness.
