Objective

Translate ManagedImage, baking, texture, Coord/Quat, PrimMesh, MeshFoundry, avatar bone math, and renderer tests.

Deliverables

  • Preserve pixel/channel buffers, geometry inputs, face indices, normals, UVs, winding, matrix order, and floating tolerances.
  • Translate every rendering [TestCase] separately.
  • Provide deterministic fixture comparison helpers without weakening tolerances.

Validation

  • All owned test cases compile on the default non-native feature set where possible.
  • Native codec cases are categorized and build-gated explicitly.
  • Failures identify unimplemented imaging/meshing/rendering members.

Prerequisite

Milestone 02 must provide the complete callable public API shim. Keep all production behavior standardized as unimplemented.

Project constraints

  • Translate the original test semantics exactly; do not weaken assertions, tolerances, inputs, errors, ordering, or interaction expectations.
  • Tests must exercise the mapped Rust API and must never call LibreMetaverse/.NET as their implementation.
  • Expected C# exceptions map to specific Rust error variants; an unimplemented panic must remain a failure.
  • Do not implement production behavior during this milestone. Update parity metadata and handover status with the change.

Implemented and pushed in commit 68ff802 (Translate imaging and meshing parity tests).

Implementation:

  • translated all 78 owned NUnit invocations: ManagedImage (3), AvatarBoneMath (2), MeshFoundry (28, including four independent LOD TestCase variants), Coord/Quat (18), and PrimMesh (27)
  • preserved image channel buffers/row flip fixtures, geometry configuration, 2-D terrain dimensions, UV vertex mutation, LOD inputs, matrix tolerance/scale fixtures, and stable C# member failure IDs
  • corrected generated public mappings for mutating ManagedImage/PrimMesh receivers, shared Coord/Quat Length receivers, rectangular terrain input shape, and in-place TransformTexCoords across MeshFoundry, SimpleRenderer, and IRendering
  • regenerated the parity catalog/report: 283 translated, 999 pending, 3 ignored-live, 4 benchmark, 0 drift

Verification:

  • focused issue suite: 78 passed
  • cargo fmt, mapping/shim/surface regeneration checks, API coverage, parity audit, Python tool tests, workspace/all-target checks, locked API compile check, no-run compile, clippy -D warnings, and cargo doc all passed
  • full cargo test --workspace remains intentionally red only at the pre-existing OarFile.LoadTerrain NotImplemented boundary documented by issue #18.

Correction after final live-spec review: the earlier failure-classification harness incorrectly treated NotImplemented results/panics as successful tests. I reopened #19 and replaced that commit in place with f79db97. The 78 separately translated cases now preserve the upstream buffers, geometry inputs, face/index/normal/UV assertions, matrix order, LOD cases, error expectations, and exact 1e-5/1e-4/0.01 tolerances while exercising only mapped public Rust APIs. Unimplemented production results and panics remain test failures; a focused run reports the exact ManagedImage constructor member ID. Verified: cargo fmt; mapping/shim/API/surface/parity generators and checks; Python tool tests; workspace/all-target and locked API compile checks; isolated imaging_meshing_semantics --no-run; workspace --no-run; clippy -D warnings; rustdoc. Parity is 283 translated, 999 pending, 3 ignored-live, 4 benchmark, 0 drift. Full cargo test remains intentionally red at the previously documented OarFile.LoadTerrain production shim boundary from #18.

Superseding the earlier invalid 68ff802/f79db97 delivery notes: the corrected implementation is commit 7691d54, pushed to main. It translates all 78 NUnit invocations owned by this issue into explicit case-specific Rust tests: ManagedImage (3), AvatarBoneMath (2), MeshFoundry (28), Coord/Quat (18), and PrimMesh (27). Every test body now calls the mapped APIs directly and carries its own assertions; the old source-name/method-name dispatcher and string-driven fixture routing are absent. The translation preserves the exact channel buffers and row flip, nearest-neighbor samples, matrix composition and 1e-4 tolerance, Coord/Quat inputs and 1e-5 tolerance, PrimMesh constructor/extrusion/viewer-mode inputs and specific IndexOutOfRange errors, MeshFoundry geometry/face/index/normal/UV checks, terrain dimensions, and all four LOD TestCase invocations. All five source hashes match the pinned checkout. There are no live-grid or native-codec cases in this owned inventory. Parity is pending=999, translated=283, ignored-live=3, benchmark=4, drifted=0. Verified locally with formatter, mapping/shim/surface/API/parity gates, Python generator tests, workspace and downstream API checks, workspace test compilation, clippy -D warnings, and rustdoc. The isolated suite compiles and reports the intended controlled red result: 0 passed, 78 failed, 0 ignored, at exact standardized unimplemented API boundaries.
