writable: false means no code can reassign window.Audio to a different value. configurable: false means no code can even call Object.defineProperty again to change those settings. If fermaw’s initialisation code tried to restore the original Audio constructor (a perfectly sensible defensive move) the browser would either fail or throw a TypeError. The hook was permanent for the lifetime of the page.
Most of the algorithms described here are quite straightforward to implement. Some of them can be written in just a few lines of code, and those that require a bit more effort can be better understood by reading through the relevant papers and links I have provided. The exception to this are those that rely on the Delaunay triangulation to work. Robust Delaunay triangulations in 3D are fairly complex and there isn’t any publicly available software that I’m aware of that leverages them for dithering in the way I’ve described.。业内人士推荐爱思助手下载最新版本作为进阶阅读
