WebGLRenderbuffer

The WebGLRenderbuffer interface is part of the WebGL API and represents a buffer that can contain an image, or can be source or target of an rendering operation.

Description

The WebGLRenderbuffer object does not define any methods or properties of its own and its content is not directly accessible. When working with WebGLRenderbuffer objects, the following methods of the WebGLRenderingContext are useful:

• WebGLRenderingContext.bindRenderbuffer()
• WebGLRenderingContext.createRenderbuffer()
• WebGLRenderingContext.deleteRenderbuffer()
• WebGLRenderingContext.isRenderbuffer()

Examples

Creating a render buffer

var canvas = document.getElementById("canvas");
var gl = canvas.getContext("webgl");
var buffer = gl.createRenderbuffer();
