Feb 1, 2026February 2026 monthly summary for iTowns/itowns: Delivered a critical bug fix for orthographic tile rendering by correcting the Tile Matrix boundaries in the Ortho.json file. This ensured accurate tile boundary representation across multiple zoom levels and prevented misrendering in orthographic views. The fix was implemented in commit aca1a705e43b78f8dd332f2f5e2716ab484efab5 with the message: fix(examples): wrong json layer properties, and validated across all affected examples. Impact: enhanced rendering fidelity, data integrity, and user trust; reduced edge-case issues in demos and tutorials; streamlined developer onboarding for new contributors by aligning example data with actual tile boundaries. Technologies/skills demonstrated: JSON schema validation and correction, debugging of data representations, Git-based version control and traceability, cross-team collaboration to align example data with rendering logic.

Nov 1, 2025November 2025: Delivered a performance-focused enhancement to the LAS Point Cloud Loader in iTowns/itowns by refactoring LASLoader to use Three.js for improved performance and attribute management (LASAttributes). Webpack was configured to avoid externalizing Three.js for worker threads, improving compatibility and performance in worker environments. These changes reduce load times for large LAS datasets, improve rendering stability, and set the stage for future point-cloud processing enhancements. Business value includes faster visualization for customers and lower operational latency.

Jun 1, 2025June 2025 monthly summary for iTowns/itowns. Focused on stabilizing atmospheric rendering and shader uniform management for improved visual fidelity and maintainability. Delivered fixes to correct a luminance uniform naming conflict between Atmosphere and SkyShader, preventing double declaration and erroneous lighting. Implemented a dedicated setUniform pathway to reliably propagate atmosphere-related material properties, and updated tile atmosphere uniforms to ensure consistent rendering across scenes. These changes reduce visual glitches, improve fidelity, and simplify future shader property updates. Commits: 1fa5a5a4d515bb08fb23c320908b5049a2baea57; fb8aa9c9a0880494a36b969c1e3f34a797227f1c.
