This article mainly introduces the use of WebGL, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Basic concept

WebGL is often regarded as 3D API, and people always think, "I can use WebGL and some amazing things to make cool 3D works." In fact, WebGL is just a rasterization engine that can draw points, lines and triangles according to your code. If you want to use WebGL to accomplish more complex tasks, it depends on whether you can provide the right code to combine dots, lines, and triangles instead of implementation. WebGL runs in the GPU of the computer. So you need to use code that can run on GPU. Such code needs to provide paired methods. One of each pair of methods is called a vertex shader. The other is called a fragment shader and uses GLSL, a strongly typed language similar to C or C++. (GL shading language). The function of each pair combined as a program (shader) vertex shader is to calculate the vertex position. According to a series of vertex positions calculated, WebGL can rasterize some elements, including points, lines and triangles.

working principle

WebGL combines JavaScript with OpenGL (OpenGL is a cross-language and cross-platform professional graphics program interface that can be used for two-dimensional or three-dimensional images) to provide hardware 3D accelerated rendering for the drawing element Canvas in HTML5, making it possible to design 3D games on web pages, and so on. Of course, if you use WebGL

In other words, it is possible to draw a function in a browser, and friends who learn higher math will definitely need this.

Support

WebGL is widely supported in the latest browsers:

Desktop computer

Apple Safari (WebKit) Google ChromeMozilla FirefoxOpera

Mobile Devic

Chrome for AndroidFirefox for Android

Thank you for reading this article carefully. I hope the article "what's the use of WebGL" shared by the editor will be helpful to everyone? at the same time, I also hope that you will support and pay attention to the industry information channel, and more related knowledge is waiting for you to learn!
