The development of online games, product displays, and indoor roaming based on WebGL technology often involves animation. 1. Periodic rendering In order to achieve periodic rendering, you can use a method setInterval() of the browser global object window object. You can call this method window.setInterval(), you can also call setInterval() directly in function form. setInterval() […]

A brief analysis of the usage and optimization of requestAnimationFrame
Introduction What is requestAnimationFrame requestAnimationFrame is an API used by browsers for timed loop operations, usually used for animation and game development. It will centralize all DOM operations in each frame, update them all at once before redrawing, and associate them with the browser’s redraw operation. Why use requestAnimationFrame instead of setTimeout or setInterval Compared […]
The difference between requestIdleCallback and requestAnimationFrame
Page smoothness and FPS The page is drawn frame by frame. When the number of frames per second (FPS) reaches 60, the page is smooth. When it is less than this value, the user will feel stuck. 1s has 60 frames, so the time allocated to each frame is 1000/60 ≈ 16 ms. So when […]
requestAnimationFrame
In web applications, there are many ways to achieve animation effects. In Javascript, it can be achieved through the timer setTimeout. In CSS3, transition and animation can be used. Canvas in HTML5 can also be implemented. In addition, html5 also provides an API specifically for requesting animations, which is requestAnimationFrame. As the name suggests, it […]

Talking about requestAnimationFrame
I am participating in the “Nuggets·Starting Plan” Foreword Timers and timed executions have been the state-of-the-art tools for JavaScript animations for a long time. While CSS transitions and animations have made some animations easier for developers, the JavaScript animation space has seen little progress over the years. The requestAnimationFrame() method came into being. This method […]
requestAnimationFrame request animation frame
What is requestAnimationFrame window.requestAnimationFrame, according to the W3C standard, we can call it to tell the browser that an animation needs to be performed, and ask the browser to call the specified callback function to update the animation before the next redraw. So this method needs to pass in a callback function as a parameter, […]
