What are the default methods of canvas?

The default methods of canvas include 2D drawing and WebGL methods. Detailed introduction: 1. 2D drawing. In JavaScript, you can obtain the 2D drawing context by calling the getContext('2d') method of Canvas, and then use the context to perform drawing operations; 2. WebGL method, by calling the getContext('2d') method of Canvas webgl') method to obtain the WebGL drawing context, and then use the context to perform 3D drawing operations.

The operating environment of this tutorial: Windows system, Dell G3 computer.

The default method of Canvas is 2D drawing. In JavaScript, you can obtain the 2D drawing context by calling the getContext('2d') method of Canvas, and then use the context to perform drawing operations.

Canvas also supports WebGL (Web Graphics Library) mode, which can perform 3D drawing. Obtain the WebGL drawing context by calling the getContext('webgl') or getContext('experimental-webgl') method of Canvas, and then use the context to perform 3D drawing operations. WebGL is a standard based on OpenGL ES (OpenGL for Embedded Systems), which can perform high-performance 3D drawing on browsers that support WebGL.

It should be noted that by default, Canvas uses 2D drawing method. If you want to use WebGL for 3D drawing, you need to explicitly specify the way to obtain the WebGL drawing context.
