This repository is a comprehensive, step-by-step tutorial series for learning wgpu, the Rust implementation of WebGPU. It contains over 30 example crates organized into beginner, intermediate, compute, and showcase categories, each demonstrating a specific GPU concept (window creation, pipelines, buffers, textures, uniforms, instancing, depth, lighting, normal mapping, HDR, compute shaders, etc.). The code is production-quality Rust with extensive use of wgpu, winit, cgmath, and bytemuck. A reusable framework crate (`code/showcase/framework`) provides a `Demo` trait, camera, model/texture loading, and pipeline builders, which many showcases implement. The repository also includes a VuePress documentation site with embedded WebAssembly demos, build scripts for WASM deployment, and a demo server. While the tutorials are well-structured and educational, there is significant code duplication across crates (e.g., identical `build.rs` files, repeated initialization boilerplate), and some showcases are stale or excluded from builds. The codebase tracks wgpu API changes closely (news files document migrations from 0.12 to 30.0), but some patterns use deprecated APIs (e.g., `wgpu::Backends::PRIMARY`, `immediate_size` in pipeline layouts). Overall, it is a valuable learning resource with solid engineering practices, though not a production library.
