WebGPU Graphics Programming: Step-by-Step

WebGPU is the next-generation graphics API and future web standard for graphics and compute, aiming to provide modern 3D graphics and computation capabilities with the GPU acceleration. To help you be familiar with this new graphics API and able to build your WebGPU applications, I will create a YouTube video series about WebGPU programming and present an easy-to-follow WebGPU application in each video episode. This repository contains all the code examples used in this video series.

This YouTube video series uses the real-world sample apps to explain the WebGPU basics, shader program, GPU buffer, and rendering pipeline. From this video series, you will learn how to create primitives and simple objects in WebGPU. As you gradually progress through the video series, you will get to grips with advanced WebGPU topics, including 3D transformation, lighting calculation, colormaps, and textures. At the same time, you will learn how to create advanced 3D WebGPU objects, including various 3D wireframes, 3D shapes, simple and parametric 3D surfaces with colormaps and textures, as well as 3D surface plots and 2D and 3D fractal graphics described by complex functions. In addition, you will explore new WebGPU features, such as compute shader and storage buffer, and how to use them to simulate large particle systems.

By the end of this video series, you will have the solid skill you need to build your own GPU-accelerated graphics and computing on the web with the WebGPU API.

Books on WebGPU, wgpu in Rust, and wgpu-py in Python

Most of the examples used in this video series are taken from my recently published book "Practical WebGPU Graphics".

I just published a new book "Practical GPU Graphics with wgpu and Rust". Rust wgpu is based on the WebGPU standard. It is a cross-platform, safe, Rust graphics API, and it runs natively on Vulkan, Metal, D3D12, D3D11, and OpenGLES, as well as on the web via WebAssembly.

I also published a new book "Practical GPU Graphics with wgpu-py and Python". wgpu-py is a Python implementation of WebGPU. It is a cross-platform, safe, Python graphics API, and it runs natively on Vulkan, Metal, D3D12, D3D11, and OpenGLES, as well as on the web via Python scripts.

Building

This repository organizes all samples with the git submodules. The sample apps are built with TypeScript and bundled using WebPack. Building the apps requires an installation of Node.js.

The following steps shows how to run the sample apps:

• Carefully watch the first video ( https://youtu.be/-hXtt4ioH5A ) to set up correct development environment.
• Click on the link for the sample app that you are interested.
• Clone or download it to your local machine.
• Install dependencies with the command: npm install.
• Compile and bundle the app with the command: npm run dev, npm run prod, or npm run watch.
• Run the live-server from VS-Code and then navigate to http://localhost:5500 or http://127.0.0.1:5500 to view the app.
