Open Source Days 2024

This talk introduces Metashade - a Python-based embedded domain-specific language (EDSL) for programming shaders (https://github.com/ppenenko/metashade). Metashade overloads Python's syntax to generate code in a target shading language. The presentation starts with a discussion of known shader programming challenges, such as managing permutations, portability, and code reuse. It then provides an overview of existing solutions, such as the C preprocessor, generics, shader graphs, transpiling, and EDSLs. Finally, the presentation details the design and implementation of Metashade and argues how it can be an improvement over the existing methods. I would base my talk of these slides, condensed to fit the 20 - 30 minute limit: https://docs.google.com/presentation/d/e/2PACX-1vQtYIwXIkMnVC6TzWTKPAtZIA6_xeUCQc8Mvyziu0qy7HDUduz_onsJ5TabxTuuVQ/pub?start=false&loop=false&delayms=3000
