A Real-time Rasterizer Little Demo Based on bgfx

Implementation of a little real-time rasterization render based on bgfx. Supports orbit/pan/zoom camera via mouse and keyboard, textured object rendering with skybox/environment maps, a selectable lighting pipeline (Blinn–Phong or PBR with IBL), and real-time shadows using shadow mapping.

Super-resolution for Downscaling on Oceanographic Fields

I frame the downscaling of oceanographic fields as a super-resolution task and address it with a deep learning approach. Building on the classical SRCNN. I optimize both the network architecture and the data pipeline, and achieve satisfactory results on the NATL60 dataset.
