Over a three-month period, contributed to ColumbiaCGUI/PolXR by developing and refining interactive 3D and XR features for Unity-based environments. Delivered runtime animation enhancements, radargram-driven workflows, and robust UI systems, focusing on scene management and data persistence to streamline user navigation and analysis. Implemented features such as normalized pose manipulation, minimap integration, radargram selection with multi-scene synchronization, and XR toolkit-driven hand tracking. Used C#, Unity, and JSON to ensure reliable asset management and cross-scene state consistency. The work emphasized iterative improvement, addressing both user experience and technical stability, and established a scalable foundation for advanced visualization and interaction capabilities.

Dec 1, 2024December 2024 performance summary for ColumbiaCGUI/PolXR Key features delivered: - Radargram persistence across scenes with UI/state synchronization (commits: e945be9..., e0ebbd8...). This ensures selected radargrams persist through scene transitions and stay in sync with the UI, improving radargram visibility and analyst workflow. - All-black mode added to the study scene (commit: 9051cb3...). Reduces glare and helps focus on radargrams during review. - Greenland minimap improvements and scene navigation (commit: c5c4587...). Enhanced minimap appearance, added blinking player marker, and enabled returning to Greenland from other scenes. - XR Enhancements and Toolkit Integration (multiple commits): end-to-end XR readiness including Interaction Toolkit setups, Greenland movement/navigation, hand tracking assets, device simulator upgrades, UI anchoring, palm-up menu improvements, and a redesigned XR main menu. Key commits include 378c754f..., 021531ce..., 5bfd8c6b..., 81a711c4..., ae09ea77..., de983fd0..., 94c17a5f... Major bugs fixed: - Radargram persistence synchronization bug: selected radargrams now stay in sync with the UI across scene transitions (commit: e0ebbd8012e9031532d148787eaefb1be28c59b9). Overall impact and accomplishments: - End-to-end radargram workflow is significantly more reliable across scenes, reducing cognitive load and saving analyst time. The XR-enabled Greenland experience now supports intuitive navigation, hand-driven UI, and a stable main menu, contributing to faster data review and an immersive user experience. Technologies/skills demonstrated: - Unity3D with XR Interaction Toolkit, hand tracking, UI anchoring to FOV, palm-up gesture controls, and scene navigation. Demonstrated robust UI/state synchronization, cross-scene data persistence, and iterative XR interface improvements.

Nov 1, 2024Delivered key UI enhancements and radargram-driven study capabilities in PolXR for 2024-11. Highlights include a more reliable minimap with asset/script integration and a refactor to ensure consistent behavior, a Greenland UI fix that corrects RectTransform local/anchored positioning for accurate UI tracking, and substantial radargram visualization/interaction improvements. Radargram features include selection, snapping, mode toggle, and multi-selection up to 8, all synchronized with UI and scene state, plus a study-scene navigation workflow driven by radargram selections. Added a dedicated study navigation button with corrected behaviors to streamline user flows. These changes reduce manual steps, improve accuracy, and establish a scalable foundation for radargram-driven study workflows across scenes.
