Over a three-month period, Castano contributed to the mrdoob/three.js repository by developing core rendering features that enhance texture handling and material realism in WebGL applications. He implemented support for EAC, BC5, and EAC_RG compressed texture formats, updating both the rendering engine and example loaders to broaden asset compatibility and improve image quality. Castano also introduced packed normal map support in the WebGL backend, modifying shader code and program initialization to enable more accurate lighting for advanced materials. His work demonstrated depth in 3D graphics, shader programming, and texture management using JavaScript, GLSL, and WebGL, with a focus on maintainability.
February 2026 monthly summary for mrdoob/three.js: Delivered Packed Normal Maps support in the WebGL backend, enabling more accurate lighting for materials that use packed normal maps. Implemented shader changes and WebGL program wiring to enable this feature when materials require it. The work advances material realism with minimal intrusion to existing pipelines. No other major features or bugs documented for this month.
