Theres no way in the shader to do something like every 4 quads since its a post process effect. We see more and more, often subtle integration of WebGL in an interface for hover, scroll or reveal effects. to be the difference between fast and slow as we progress further into these articles Are you sure you want to create this branch? 38 JavaScript Background Effects April 29, 2021 Collection of hand-picked free vanilla JavaScript background effect code examples: change background color or image, animated, with canvas and etc. and a texture where every mip level is a different color. Most of the stuff in here is just bootstrapping. How does the GPU know which colors to make each pixel it's drawing for the tiny cube? But you can implement the same concepts using other libraries. Three.js is a JS graphics library that is used for rendering 3D graphics in browsers. Here's quick table of contents for this article.
