PROFILE
Ignacio Castaño
Contributed to the mrdoob/three.js repository by delivering three core rendering features over three months, focusing on expanding texture format support and enhancing material realism in WebGL applications. Developed EAC, BC5, and EAC_RG compressed texture handling, updating both the rendering engine and example loaders to support broader asset pipelines and higher visual fidelity. Implemented packed normal map support by modifying shader code and WebGL program logic, enabling more accurate lighting for advanced materials. The work demonstrated expertise in 3D graphics, shader programming, and texture management, using JavaScript, GLSL, and WebGL to integrate low-level rendering improvements into a large codebase.

Dec 1, 2025December 2025 monthly summary for mrdoob/three.js: Delivered a feature enhancement to WebGL texture loading by adding BC5 and EAC_RG compressed texture support in the webgl_loader_texture_ktx example, expanding rendering capabilities and asset compatibility. The work included updating the example to test BC5 and EAC_RG formats (commit 55b4bbb7ef7e29b214b9732ba2e5119b781a31ee). No major bugs fixed this month; focus was on feature development and validation. Business value includes broader format support for WebGL apps, enabling higher visual fidelity and expanded asset pipelines for developers using three.js.
