Worked on the iTowns/itowns repository, delivering features and fixes focused on 3D rendering, GPU optimization, and atmospheric effects. Over five months, implemented a realistic sky and atmosphere system, standardized fog rendering using Three.js, and optimized texture management by introducing texture arrays to reduce GPU slot pressure. Addressed memory management by developing a render target caching mechanism and improved user interaction through more accurate object picking and stable sky rendering. The work involved extensive use of JavaScript, GLSL, and WebGL, with careful attention to maintainability, performance, and compatibility across the rendering pipeline, supported by clear commit practices and unit testing.

Mar 1, 2026March 2026 monthly summary for iTowns/itowns. Delivered two critical rendering fixes that improve user interaction and visual stability: (1) Object Picking Accuracy: switched from color-based to alpha-based picking to ensure only visible objects are selectable and avoid mispicks with background colors. (2) Sky Flicker Fix for Logarithmic Depth: resolved distant sky flickering due to depth precision, stabilizing atmospheric rendering in 3D scenes. These fixes reduce user friction, improve model interaction accuracy, and enhance perceived performance in complex scenes.

Jan 1, 2026Monthly summary for 2026-01 focusing on key developer contributions in iTowns/itowns. Delivered a core feature to optimize memory management in rendering by implementing a render target caching mechanism that tracks usage to prevent premature unloading of textures during rendering. This work involved per-view isolation of render target management, wrapping the cache in a dedicated class, and refining disposal logic. In addition, updated architectural flow by moving updateLayersUniformsForType out of LayeredMaterial to simplify the codebase and improve maintainability. The changes were accompanied by unit tests, and fixes addressing a render-target-related memory leak and related test issues.

Oct 1, 2025October 2025 monthly summary for developer work on iTowns/itowns. Focused on rendering pipeline optimization to improve GPU resource usage and scalability. Key feature delivered: - Renderer Texture Array Optimization: Refactored renderer texture handling to use texture arrays, packing multiple textures into a single array to reduce per-layer texture slots and enable more layers to render concurrently. Related commit: b46b807a7d7fcacf27d65acbf9c77f19c1c70384. - Shader and texture management: Updated shader uniforms and introduced a new mechanism for creating and managing texture arrays to support the optimization. Bugs fixed: - No major bugs fixed this month. Overall impact and accomplishments: - Significantly reduced GPU texture slot pressure per layer, paving the way for higher scene complexity and improved rendering throughput. The groundwork supports future enhancements such as additional layers and richer textures without increasing draw calls. Technologies/skills demonstrated: - GPU texture arrays (Texture2DArray), shader programming (GLSL/Shader uniforms), renderer refactoring, performance-oriented thinking, and careful integration with existing rendering pipeline. - Version control discipline with clear, scoped commits and traceability to feature work.
