Worked on enhancing 3D visualization and browser-based file system capabilities across rerun-io/rerun and apache/opendal. In rerun, delivered configurable camera controls for 3D viewers, introducing UI sliders and blueprint-based properties to manage camera speed and perspective, supporting both first-person and orbital navigation. These features were integrated using C++, Python, and component-based architecture, improving user navigation and interactivity in complex scenes. For apache/opendal, implemented an OPFS backend using Rust and WebAssembly, enabling in-browser file system operations such as directory creation, reading, writing, and listing. Focused on robust error handling, cross-platform compatibility, and maintainable code structure throughout the development process.

Month: 2025-07 — Delivered camera control enhancements for spatial 3D views in rerun. Implemented blueprint-based Eye Controls 3D (Camera) properties to govern camera kind and speed, enabling configurable perspectives (first-person, orbital) and translation speeds. Integrated new controls into spatial 3D view properties for enhanced interactivity and customization. These changes lay groundwork for richer 3D exploration and more adaptive visualizations.
