Junhao Duan contributed to the Tencent/tgfx repository by developing cross-platform animation frame rendering for the Hello2D demo, targeting Mac, iOS, Android, Web, OHOS, and Windows. He refactored the drawing pipeline to leverage display link callbacks, ensuring smoother animations and consistent lifecycle management across platforms using C++ and TypeScript. In addition, he enabled the DisplayList zoom blur visual effect in Hello2D, improving demo visual fidelity with a minimal, low-risk code change. His work focused on graphics programming, cross-platform development, and UI rendering, resulting in more reliable animation performance and enhanced visual quality for product demonstrations and stakeholder presentations.
