Worked on the mrdoob/three.js repository to enhance the PCDLoader by improving binary PCD file loading reliability and performance. Focused on JavaScript, 3D graphics, and binary data handling, the work introduced a new helper for robust binary data type parsing and refactored header parsing to eliminate reliance on TextDecoder for binary headers. These changes streamlined the loader’s efficiency, reduced load times for large datasets, and increased stability in production environments. The update also included new test coverage and example updates to validate binary PCD loading, while unifying variable naming and refactoring code for better maintainability and clarity.
