PROFILE
Greg Ou
Greg Yiwen contributed to the ColumbiaCGUI/PolXR repository by developing and stabilizing core XR and game features over a three-month period. He enhanced the DEM loading pipeline to visually distinguish bedrock assets using color interpolation in Unity and Shader Graph, improving data interpretation for users. Greg addressed gameplay stability by refactoring Fusion addons and implementing Android compatibility, ensuring reliable player spawning and runtime object loading. He also resolved XR interaction bugs, such as radargram snapping, by refining XRGrabInteractable logic and Rigidbody behavior in C#. His work emphasized maintainability, repository hygiene, and deployment readiness, demonstrating depth in Unity, C#, and networking technologies.

Nov 1, 2024November 2024 monthly summary for ColumbiaCGUI/PolXR. Focused on visual rendering improvements and repository hygiene. Delivered a bedrock rendering enhancement in the DEM loading pipeline to visually distinguish bedrock via color interpolation (restricted to assets named 'bedrock'), and completed a maintenance change to align Git ignore conventions. These changes improve data interpretation for DEM analyses and reduce repo fragmentation risks.
