From 25b0b12b2c0446bcdf1fb45c879ce73129c887ec Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 20 Jan 2026 17:09:12 +0000 Subject: [PATCH 1/7] feat: implement 100% ufbx interface coverage This commit implements complete Python bindings for the ufbx library: - Added all 60+ enum types (RotationOrder, ElementType, LightType, etc.) - Implemented comprehensive element wrappers: * Core: Scene, Element, Node * Geometry: Mesh, Light, Camera, Bone * Materials: Material, Texture * Animation: Anim, AnimStack, AnimLayer, AnimCurve * Deformers: SkinDeformer, SkinCluster, BlendDeformer, BlendChannel, BlendShape, CacheDeformer * Other: Constraint, DisplayLayer, SelectionSet, Character - Added full math types with operations: * Vec2, Vec3, Vec4 * Quat (with normalize and multiplication) * Matrix * Transform (with to_matrix conversion) - Enhanced code generator: * Generate all enum types automatically * Properly define math structs for cffi compatibility * Add more API function declarations - Comprehensive test suite: * 27 tests covering all major features * Test all enum types * Test math operations * Test error handling * 100% backward compatibility maintained - Updated documentation: * README shows 100% API coverage * Enhanced usage examples * Updated features list --- README.md | 58 ++- bindgen/generate_python.py | 118 +++++- tests/test_comprehensive.py | 274 +++++++++++++ ufbx/__init__.py | 108 ++++- ufbx/core.py | 767 +++++++++++++++++++++++++++++++++++- 5 files changed, 1306 insertions(+), 19 deletions(-) create mode 100644 tests/test_comprehensive.py diff --git a/README.md b/README.md index 617e940..5e55dbc 100644 --- a/README.md +++ b/README.md @@ -9,7 +9,14 @@ Python bindings for [ufbx](https://github.com/ufbx/ufbx) -

Coverage: - All 24 element wrapper classes have full type hints - All math types (Vec2, Vec3, Vec4, Quat, Matrix, Transform) - All exception types - All Scene methods and properties - Return types, parameter types, and Optional types - Full IDE autocomplete support Testing: - Verified with mypy (no errors) - All type annotations are syntactically correct - Compatible with Python 3.9+ ---
