Web/API/WebGLRenderingContext/bindFramebuffer

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

Syntax

void gl.bindFramebuffer(target, framebuffer);

Parameters

target: 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.

framebuffer: A WebGLFramebuffer object to bind.

Return value

None.

Exceptions

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

Examples

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.

gl.getParameter(gl.FRAMEBUFFER_BINDING);
