WebGLRenderbuffer

WebGLRenderbuffer 接口是 WebGL API 的一部分,它提供了一个用于保存一个图像的缓存,并且可以用于渲染操作的源或者目标。

摘要

WebGLRenderbuffer 对象保存的内容不能被直接访问,因此这个对象没有提供任何用于操作其自身内容的方法和属性。当需要使用 WebGLRenderbuffer 对象的功能时,需要使用 WebGLRenderingContext 对象的以下方法:

示例

创建一个 render buffer 对象

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