The WebGL API provides several constants that are passed into or returned by functions. All constants are of type GLenum.
Standard WebGL constants are installed on the WebGLRenderingContext and WebGL2RenderingContext objects, so that you use them as gl.CONSTANT_NAME:
Some constants are also provided by WebGL extensions. A list is provided below.
The WebGL tutorial has more information, examples, and resources on how to get started with WebGL.
These constants are defined on the WebGLRenderingContext interface.
