In December 2024, Anders Kristoffersen refactored Spherical Harmonics and k-nearest neighbors utilities within the nerfstudio repository, moving shared logic from the splatfacto module into dedicated utility modules. This work, implemented in both Python and C++, focused on code refactoring, module organization, and utility function extraction to improve maintainability and reduce duplication. Anders updated the Spherical Harmonics encoding to use a degree-based representation, enhancing clarity and consistency across the codebase. By centralizing reusable logic and establishing a clearer module structure, this refactor laid the groundwork for future enhancements to Spherical Harmonics and kNN features within nerfstudio.
December 2024: Refactored Spherical Harmonics (SH) and kNN utilities into dedicated modules and updated SH degree encoding for clarity and consistency in nerfstudio. This refactor improves maintainability, reduces duplication, and centralizes reusable logic, setting the foundation for future SH/KNN enhancements.
