joy1412.cn “嘟先生学WebGL / 嘟嘟MD” is a personal tech blog positioned as a front-end learning site that combines blog posts, knowledge management, and documentation lookup. The crawled content shows that its core focus is Three.js/WebGL, while also covering front-end notes on React, Vue, ES6, TypeScript, Git, Node.js, blog building, and related topics. The site has an ICP filing, and overall it feels more like a personal knowledge base and case-study showcase than a standard online education platform.
The most distinctive part of the site is its Three.js online demos, including a stylish 3D Earth, JSON maps, human body scanning, holographic humans, showroom walkthroughs, dynamic skin/material switching and disassembly, and a character roaming through a starry sky. These are useful for previewing visual effects and learning implementation ideas. In addition, the site provides technical documentation-style content, such as Git usage manuals, Markdown tutorials, npm commands, and package.json explanations, with articles organized by categories, tags, and archives.
Articles and online demo previews appear to be free to access. Some premium demo source code is sold through a Taobao store. Prices listed in the crawled content range from 19.9 yuan to 99 yuan, such as 19.9 yuan for the stylish 3D Earth, 99 yuan for the showroom walkthrough, and 49.9 yuan for human body scanning. Payment and after-sales details should be confirmed on the Taobao store page. The website itself does not display a complete license agreement or terms of service.
The advantages are that the Chinese content is easy to understand, the Three.js demos have clear visual results, and the site is suitable for beginners who want to preview effects first and then purchase source code for breakdown and study. The blog also compiles a fair amount of basic front-end notes, with relatively complete search and navigation entry points. The downsides are that the content is based on personal learning notes, so depth, accuracy, and update consistency may vary. The source code is developed based on the official r129 version, which is relatively old, so real-world projects may need adaptation for newer Three.js versions. Information about source-code licensing, maintenance, and Q&A support is also not very transparent.
It is suitable for individual developers, students, and anyone learning Three.js, WebGL, or front-end visualization, as well as people who need quick inspiration for 3D presentation ideas. It is less suitable for teams that need systematic courses, enterprise-grade technical support, or ready-to-use commercial delivery solutions.
The domain is .cn and has a Min ICP filing, targeting Chinese users. It can generally be accessed directly from mainland China. The Taobao-based source-code purchase process also better matches the habits of domestic Chinese users.
