Tom Simons developed and maintained the Netherlands3D/twin repository, delivering a robust 3D geospatial visualization platform with advanced CityJSON and GeoJSON data integration. He engineered scalable rendering pipelines and masking workflows, refactored core architecture for maintainability, and implemented features such as polygon editing, asset import/export, and project versioning. Using C#, Unity, and Shader programming, Tom improved performance, reliability, and UI/UX for complex GIS data. His work included asynchronous programming for concurrency, secure credential management, and extensible data pipelines. The depth of his contributions is reflected in the platform’s stability, extensibility, and ability to handle large, heterogeneous 3D datasets efficiently.
February 2026 (Netherlands3D/twin) focused on usability, reliability, and maintainability. Key features delivered include improvements to polygon/multipolygon UX and layer organization (folder structure, naming, and icons) to simplify complex geometry management; credential handling improvements for project imports to correctly differentiate local vs remote assets and ensure proper authorization; the introduction of a project versioning system with backward compatibility and upgrade templates; and a architecture refactor that simplifies data loading paths by removing legacy StartLoadingData and consolidating loading logic. Major bug fixes addressed credential-related import errors, reducing failures during project load. Overall impact: smoother polygon workflows, more reliable project upgrades, and a cleaner, more maintainable codebase with improved data loading reliability. Technologies/skills demonstrated: UI/UX enhancements for GIS layers, secure asset handling, code refactoring and architecture simplification, versioning and template management, and extension-method usage for scheme determination.

January 2025 (Netherlands3D/twin): Focused on stabilizing core parsing and transforms while strengthening performance, reliability, and maintainability. Key features were delivered to speed up asset import, startup, and project loading; bugs were fixed to prevent data loss and runtime errors; and the codebase was reorganized for faster onboarding and release readiness. Key features delivered: - OBJ parsing queue introduced to reduce mesh mixing and parsing contention, improving import reliability. - Startup loading flow improved by moving default project loading to Awake phase, ensuring the project download starts earlier. - Debug logging and Utrecht default path added to simplify troubleshooting and initial setup. - Update Utrecht project template to align with latest scaffolding and defaults. - Global Namespace Cleanup for 3D Engine Modules and Folder organization: standardized namespaces across modules (AreaDownload, AssetBundle, Google Reality Mesh, Indicator, ObjectInformation, ObjectLibrary, ObjImport, OGC 3D Tiles, ProfileRendering, Sun, etc.) and restructured folders to improve maintainability. - Codebase cleanup and namespace normalization: removal of test code/assets, cleanup of empty folders, and moving scripts to organized folders. UI refactor introduced a generic UI folder and moved UI scripts accordingly. - UI/UX improvements: UI folder restructuring to improve tabbing and properties organization. - Bounding box caching: added Bbox library to cache bounding boxes when loading a project and updated ImportAdapter to fill the BBox Cache for faster loads. - WMS/WFS bounding box support: added and refined bbox handling and CRS parsing, improving geospatial data integrity. - Release packaging preparation: assembled packaging workflow to enable smoother releases. Major bugs fixed: - Core stability and parsing fixes across saving, transforms, event handling, duplicates, namespaces, and parsing; regression around project template loading addressed. - Ensured saved transforms override georeferenced transforms to preserve user tweaks. - Fixed event unsubscription for standard layer functionality to prevent leaks. - Fixed namespace and XML parsing issues across multiple modules (ProfileRendering, ObjectInformation, OGC 3D Tiles, etc.). - Reverted unintended project template changes and performed cleanup of test code/assets to stabilize the codebase. - Fixed missing namespaces introduced by script moves/refactor and cleaned up meta/file integrity issues. - Fixed duplicate keys for WFS, invalid URL handling, and other minor regressions uncovered during refactors. Overall impact and accomplishments: - Significantly reduced startup time and improved reliability of project loading, import, and parsing. The codebase is now more maintainable, with standardized namespaces and clearer project structure, enabling faster feature delivery and easier onboarding. Release readiness has improved, enabling smoother deployment cycles. Technical debt related to test code/assets has been reduced while key performance optimizations were implemented. Technologies/skills demonstrated: - C#, Unity-like project structure, AssetBundle handling, and namespace normalization. - Performance optimization (parsing queue, startup sequencing) and caching strategies. - GIS concepts (WFS/WMS, bounding boxes, CRS) and robust data loading pipelines.
