Cross-platform, graphics API agnostic, "Bring Your Own Engine/Framework" style rendering library.
Project mention: Layers All the Way Down: The Untold Story of Shader Compilation | news.ycombinator.com | 2025-05-18BGFX (https://github.com/bkaradzic/bgfx) uses a different approach. You basically write your shader in a GLSL-like language but it's all just (either very clever or very horrible) macro expansions that handles all the platform differences.
