Three.js 零基础入门：手把手打造交互式 3D 几何体展示系统
There isn’t a ton of innovation when it comes to design in the Wi-Fi extender space. Most of the ones you’ll find today are rounded rectangles roughly the size of your hand that plug into a standard wall outlet. They usually have a few indicator lights that will show you when the extender is connected, how strong its signal strength is and when there’s a problem, and some will even have moveable external antennas that companies claim provide even better Wi-Fi signal. Generally, they are pretty simple to install and get connected, but if you’re struggling with how to set up your Wi-Fi extender, there are plenty of YouTube videos you can check out.

Instead of perturbing each pixel in the input image at random, we can choose to dither by a predetermined amount depending on the pixel’s position in the image. This can be achieved using a threshold map; a small, fixed-size matrix where each entry tells us the amount by which to perturb the input value , producing the dithered value . This matrix is tiled across the input image and sampled for every pixel during the dithering process. The following describes a dithering function for a 4×4 matrix given the pixel raster coordinates :
