Fixed discrepancies between source code and documentation: - AsyncLoader: Document Initialize() ignores workerThreadCount, Submit() doesn't do actual async loading, Update() is stub - ResourceManager: Document UnloadUnused() and ReloadResource() are stubs - ResourceCache: Document OnZeroRefCount() and Flush() are stubs - ResourceDependencyGraph: Document TopologicalSort() returns empty (stub) - ResourceFileSystem: Document GetResourceInfo() doesn't fill modifiedTime, EnumerateResources() is stub - FileArchive: Document Enumerate() is stub - ResourcePackageBuilder: Document AddDirectory() is stub - ImportSettings: Document LoadFromJSON/SaveToJSON are stubs - TextureImportSettings/MeshImportSettings: Document JSON methods are stubs - TextureLoader/MeshLoader/MaterialLoader/ShaderLoader/AudioLoader: Document GetDefaultSettings() returns nullptr - AudioLoader: Document ParseWAVData() is stub, Load() doesn't parse WAV headers - ShaderLoader: Document DetectShaderType/ParseShaderSource are stubs - MaterialLoader: Document ParseMaterialData() is stub - Texture: Document Create() mipLevels=0 behavior, GenerateMipmaps() returns false - Mesh: Document MeshLoader::Load() is example only - IResourceLoader: Document GetDefaultSettings() returns nullptr for all loaders

AABB / OBB
轴对齐包围盒 (AABB) 和有向包围盒 (OBB)。
头文件: #include <XCEngine/Math/AABB.h>
命名空间: XCEngine::Math
AABB
AABB 在 Math 库中通过 Bounds 类型实现,参见 ./bounds/bounds.md。
OBB - 有向包围盒
OBB 是可以任意方向旋转的包围盒。
struct OBB {
Vector3 center;
Vector3 extents;
Matrix4 transform;
};
构造函数
OBB()- 默认构造OBB(const Vector3& center, const Vector3& extents)- 从中心和半长构造
