A physically-based CPU path tracer written from scratch in C++. Reads Mitsuba-style XML scenes and renders them with unidirectional path tracing, Multiple Importance Sampling (MIS) and Next Event Estimation, in a modular architecture. Documented with MkDocs and Doxygen.

An interactive analytical BSDF viewer built in C and Vulkan, developed at the XLIM Laboratory. Enables real-time GPU-accelerated visualisation and manipulation of analytical material models, with efficient parallel computation for interactive performance. I contributed to this project as part of my research internship.

A small, well-tested implementation of Model-Agnostic Meta-Learning (MAML) for any PyTorch nn.Module, built on torch.func. Supports full first- and second-order MAML through one code path, plus the Meta-SGD and ANIL variants. Fully typed and tested.

A self-contained procedural planet renderer in WebGL. Adapted from my computer graphics coursework.
