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.
