How To Enable WebGL in Chrome, Safari and Firefox

WebGL is also known as the Web Graphics Library. It is a Javascript API that enables us to render interactive 2D and 3D graphics on any browsers without downloading multiple plugins. WebGL now fully supports all other web standards which makes it possible to easily use image processing, CPU acceleration in most web pages. The most important use of WebGL is that it helps to make browsers, javascript and graphics drivers better, this point we will introduce some reasons why we need to WebGL in this article. However, even though  it claims  that it supports all major desktop browsers to some degree. But many times it fails in Chrome or Firefox. Whether it does not work properly or is not enabled, we will walk you through the steps to fix it.


Part 1: Why Need to Enable WebGL in Browsers

Traditionally, nearly all browsers always use CPU to render content and graphics, but today, with the emergence of WebGL, some mainstream browsers are using GPU acceleration to render the complex graphics without using plug-ins.


1) Since WebGL is based on OpenGl, so developers could make full use of it to increase a lot more speed of JavaScript, it provides more abilities to develop 3D applications.  

2) The Browser with WebGL is capable of collecting all garbage that generated by webpages.


3) WebGL could produce the complex visual effects by using shaders.


4) Allows users to develop simple 2D games and applications,


5) and more...


It is noteworthy that WebGL content is not currently compatible with low-end mobile device as the CPU is not powerful enough and lack of enough memory to process the WebGL content. So then you’re trying to load WebGL content on your mobile browser, you might get a warning messages.


Part 2. Turn On WebGL in Google Chrome
