PROFILE
Melquiades Xiong
During a two-month period, Ziyi Xiong contributed to the HarrisonKramer/optiland repository by developing three features focused on tutorial clarity and dynamic optic surface management. Using Python, Jupyter Notebooks, and object-oriented programming, Ziyi updated surface tutorials for API compatibility, resolving a TypeError and improving onboarding by clarifying constructor usage and notebook formats. In subsequent work, Ziyi enhanced visualization controls for lens surface sag and introduced a method to remove surfaces from optics, validating these changes with targeted unit tests. The work demonstrated careful attention to code maintainability, robust type safety, and improved user experience for both new and existing users.

Dec 1, 2025December 2025 monthly summary for HarrisonKramer/optiland focused on delivering Surface Tutorials API compatibility and clarity improvements. Consolidated two tutorial updates into a single, coherent release: (1) fixed a TypeError by aligning the Surface constructor usage with the current API in Tutorial_10a; (2) updated the Forbes surface tutorial notebook to adopt the new freeform_coeffs key format and set the field type before drawing for enhanced clarity and functionality. These changes reduce runtime errors, improve tutorial reliability, and streamline onboarding for new users.
