Oct 1, 2025October 2025 Monthly Summary – iTowns/itowns Key features delivered: - Geographic module refactor and TS migration: import only the necessary three.js components and update TypeScript exports to enable granular, modular usage and better tree-shaking. - TileMesh/TileLayer rendering improvements and TS migrations: consolidated tile-related improvements, improved layer opacity handling, memory management for elevation tiles, and TypeScript migration for TileMesh and OBB; updated docs. - Proj4 dependency update: upgraded to v2.9.10 with safer import patterns to improve compatibility. - Copc Loader Example Enhancement: ensured the copc loader example runs by updating HTML to load dat.gui, improving the demo experience for users. - CI/release workflow hardening: fixed missing GITHUB_TOKEN handling to prevent permission errors during release assets upload. Major bugs fixed: - Rendering: Accurate transparency when some point classes are disabled, ensuring transparency flag correctly reflects visibility and improving visual accuracy of point clouds. - Non-disposed raster tile and related elevation/TileLayer issues addressed as part of the TS migrations and helpers. Overall impact and accomplishments: - Improved developer experience through modular code organization and TS migrations, enabling easier maintenance and faster onboarding. - Increased reliability and automation in the release process, reducing build/regression risks. - Enhanced visual quality and performance for large-scale point cloud rendering, with better memory management for elevation tiles. Technologies/skills demonstrated: - TypeScript migrations and modular imports (three.js components) with improved exports. - Three.js integration and performance-conscious rendering improvements. - Dependency management (Proj4) and CI/CD governance (GITHUB_TOKEN handling). - Documentation maintenance accompanying code changes to reflect updated architecture.
