From Pure ISO C++20 To Compute Shaders - Koen Samyn - CppCon 2025

https://cppcon.org --- From Pure ISO C++20 To Compute Shaders - Koen Samyn - CppCon 2025 --- Modern graphics and compute projects still force developers to write every kernel twice—once in C++ for CPU debugging and again in GLSL/HLSL for the GPU.  This session shows how entirely standard C++20 can unify those worlds. C++ features such as constexpr, user defined literals and templates are used to write C++ source code that can be transpiled easily into GLSL or HLSL. Attendees will learn three reusable techniques: Metadata as templates, not attributes – e.g. resources like Buffer＜float,0,2＞ encode set & binding in ordinary non‑type parameters, so any ISO‑compliant compiler accepts the code and tooling can reflect it without macros or vendor keywords. CPU work‑group emulation – std::execution::par_unseq plus a per‑group std::barrier faithfully reproduces compute shader parallellism, enabling single‑step debugging in a familiar debugger. AST‑driven transpile & reflection – a lightweight Clang LibTooling pass converts the same source file to GLSL, inserts #line mappings for error reporting, and emits a JSON descriptor table that engines can consume automatically. If you want to dive into the world of compute shading without leaving the familiarity of C++, this is the talk for you. --- Slides: https://github.com/CppCon/CppCon2025/...

Over the past decade he has built and optimized compute-shader pipelines for lighting, physics, and inverse kinematics. In the classroom Koen mentors future developers on topics such as C++20/23 concurrency, data-oriented design, and the nuances of dispatching workloads across CPU and GPU. --- CppCon is the annual, week-long face-to-face gathering for the entire C++ community. The conference is organized by the C++ community for the community. You will enjoy inspirational talks and a friendly atmosphere designed to help attendees learn from each other, meet interesting people, and generally have a stimulating experience. Taking place this year in Aurora, Colorado, near the Denver airport, and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts.
