Open Source Days 2024

AYON represents the next stage in the evolution of the popular open-source platform, OpenPype, developed by the pipeline specialists at Ynput. It was created by a team of industry veterans who had previously worked on demanding productions, enduring excessive hours during crunch times. Eager to break away from ‘the norm’ and discover a better way of working where artists can go home on time, they first created AYON in 2018 as an in-house pipeline tool, building on top of available open-source technology and open-sourcing AYON itself too. Fast forward six years, and it is now deployed globally in hundreds of studios working on animation and VFX projects. This open-source platform is designed to streamline creative studios’ workflows, ensuring seamless project delivery from concept to completion.

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

As a 3-year-old distribution, the AlmaLinux community has been through a lot! This year we shifted our goals from being a RedHat Enterprise Linux clone to being RHEL binary compatible, which has opened a whole new world for us. Come hear about the new stuff we've been doing, what we think we're good for, and how you can get involved.

In this session we will present the latest development on two open source repositories from Adobe: USD File Format plugins and Substance 3D Connector
