Worked on the asam-ev/OpenMATERIAL repository, focusing on enhancing the material system’s physical realism and computational reliability. Over three months, contributed C++ and Python code to clarify BRDF definitions, add physically plausible properties, and improve rendering fidelity. Developed and refined validation rules for XOMP files, ensuring correct units and valid ranges for key material parameters, while updating documentation in adoc to reduce onboarding time and misinterpretation. Addressed a density calculation bug in the core physics engine, implementing targeted code refactoring to stabilize property predictions. Emphasized maintainability and traceability through clear commit practices and comprehensive technical writing throughout the project.
