The WebGLRenderingContext.bindFramebuffer() method of the WebGL API binds a given WebGLFramebuffer to a target.


void gl.bindFramebuffer(target, framebuffer);


A GLenum specifying the binding point (target). Possible values:
  • gl.FRAMEBUFFER: Collection buffer data storage of color, alpha, depth and stencil buffers used to render an image.
  • When using a WebGL 2 context, the following values are available additionally:
    • gl.DRAW_FRAMEBUFFER: Equivalent to gl.FRAMEBUFFER. Used as a destination for drawing, rendering, clearing, and writing operations.
    • gl.READ_FRAMEBUFFER: Used as a source for reading operations.
A WebGLFramebuffer object to bind.

Return value



A gl.INVALID_ENUM error is thrown if target is not gl.FRAMEBUFFER, gl.DRAW_FRAMEBUFFER, or gl.READ_FRAMEBUFFER.


Binding a frame buffer

var canvas = document.getElementById("canvas");
var gl = canvas.getContext("webgl");
var framebuffer = gl.createFramebuffer();

gl.bindFramebuffer(gl.FRAMEBUFFER, framebuffer);

Getting current bindings

To check the current frame buffer binding, query the FRAMEBUFFER_BINDING constant.

[1] WebGL 2 is enabled by default in Firefox Nightly. To enable it in a release version of Firefox, set the preference webgl.enable-prototype-webgl2 to true in about:config.

[2] To use an experimental implementation of WebGL 2 in Chrome, you have to start Chrome with the runtime flag --enable-unsafe-es3-apis.
