PROFILE
Seungho Baek
Contributed to the Samsung/TizenFX repository by delivering a range of UI, rendering, and media features for the Tizen NUI framework. Focused on architectural improvements such as rendering system refactors, API deprecation, and versioning to streamline future development and migration. Developed enhancements in animation, 3D math, and video playback, introducing new APIs and optimizing performance using C#, C++, and interop programming. Implemented thread-safe mechanisms for rendering and resource management, improved image loading reliability, and expanded test coverage. The work emphasized maintainable code organization, robust error handling, and cross-platform compatibility, supporting both developer experience and end-user performance across Tizen devices.

Aug 1, 2025Samsung/TizenFX – 2025-08 Monthly Summary: This period focused on delivering core media, 3D content, and developer-experience improvements with clear business value and robust test coverage. Key features delivered: - VideoView frame interpolation with native image source: public C# APIs to set/get frame interpolation interval and native image source, interop methods, and a test sample demonstrating frame cycling via a timer. Commit: 32023fc49579559d1a8b18e8e2f73e8133da32ad. - Model loading status API and events: adds LoadingStatus to Tizen.NUI.Scene3D.Model, ensures ResourcesLoaded fires on success and failure, and defines ModelLoadingStatusType (Preparing, Ready, Failed). Commit: a01566a7e38d33d4a98cfded259c55fe6adb7443. - Enhanced 3D math API surface: exposes Dot and Cross for Vector3/Vector4, and adds static Normalize, Inverse, Distance, and Reflect for Vector3, Vector4, and Rotation. Commits: a892baec26893bdce9bbeffa947b87e35d0c8ff5; 938f4d33858b0fcc20dbad7636b9b4a8b0916996. - Toggle actor 'ignored' state from update thread: adds SetIgnored to FrameUpdateCallbackInterface and a sample FrameUpdateCallbackToggleTest demonstrating the behavior. Commit: 13a3b20923bb128dba145a6c708fb31548159962. Major bugs fixed: - Reliable reporting of model load outcomes: ResourcesLoaded now fires on both success and failure, enabling consistent handling in apps. - Thread-safety in update loop: SetIgnored/GetIgnored support allows safe control of actor state from the update thread, reducing race conditions. Overall impact and accomplishments: - Improved developer experience and app robustness for media playback, 3D content, and real-time updates. - Faster integration with clearer event semantics, richer 3D math utilities, and safer multi-threaded state management. Technologies/skills demonstrated: - Interop and public API design for native imagery and frame control; C# API exposure. - Expanded 3D math APIs (Dot, Cross, Normalize, Inverse, Distance, Reflect) across Vector3/Vector4/Rotation. - Thread-safety considerations in update loops and test-driven samples for verification.

May 1, 2025May 2025 monthly summary for Samsung/TizenFX: Delivered three high-impact enhancements focused on UI animation, rendering performance, and resource management. Implemented Spring-like animation in NUI with new AlphaFunction constructors and interop; added View.Ignored to skip rendering of invisible Views on the render thread; extended TextureSet with RemoveTexture and RemoveSampler by index. Included tests (SpringAlphaFunctionTest) and API exposure for interop. These changes improve animation fidelity, reduce render overhead, and enable finer texture management, translating to smoother user experiences and lower resource usage on a range of devices.
