Worked on CesiumGS/cesium over four months, delivering seven features and resolving three bugs focused on 3D graphics and interactive scene management. Enhanced picking and selection with multi-select and drill-picking, improved label rendering robustness, and optimized memory handling for pixel readouts. Refactored texture atlas and billboard image handling to streamline asynchronous loading and promise management, reducing memory leaks and improving API clarity. Addressed rendering accuracy through shader updates and improved test coverage. Used JavaScript, WebGL, and GLSL to implement these changes, emphasizing performance optimization, code reliability, and comprehensive documentation to support both user experience and developer productivity.
