Graphics

Introduction The web has come a long way from static HTML pages to rich, interactive applications that rival native desktop software. Two emerging technologies are at the heart of this transformation: WebAssembly (Wasm) – a low‑level binary format that brings near‑native performance to the browser while preserving safety and portability. WebGPU – the next‑generation graphics and compute API for the web, offering explicit, high‑performance access to modern GPUs. Individually, each technology is powerful. Together, they form a compelling stack for building high‑performance graphics, simulations, and compute‑heavy workloads that run directly in the browser without plug‑ins. This article provides an in‑depth look at how WebAssembly and WebGPU complement each other, walks through a complete example from Rust source to a running WebGPU demo, and discusses best practices, tooling, and real‑world use cases. ...

Why WebGPU Matters: A Comparison with WebGL Core Architecture and Terminology Setting Up a WebGPU Development Environment Writing Shaders with WGSL Practical Example: A Rotating 3‑D Cube Performance Tips & Best Practices Debugging, Profiling, and Tooling Real‑World Use Cases and Success Stories The Future of WebGPU Conclusion Resources Introduction The web has evolved from static pages to rich, interactive experiences that rival native applications. Central to this evolution is the ability to harness the power of the graphics processing unit (GPU) directly from the browser. For more than a decade, WebGL has been the de‑facto standard for 3‑D graphics on the web. However, as developers demand more compute‑intensive workloads—real‑time ray tracing, machine‑learning inference, scientific visualization—the limitations of WebGL’s API surface become apparent. ...

It offers both lossy and lossless compression, supports transparency (alpha), animation, and even ICC color profiles—all within a single file type. While many developers know how to use WebP (e.g., <picture> tags, srcset attributes), fewer understand what happens under the hood when a .webp file is created, transmitted, and rendered. ...
