Web/API/WebGLRenderingContext/framebufferRenderbuffer

The WebGLRenderingContext.framebufferRenderbuffer() method of the WebGL API attaches a WebGLRenderbuffer object to a WebGLFramebuffer object.

Syntax

void gl.framebufferRenderbuffer(target, attachment, renderbuffertarget, renderbuffer);

Parameters

target: A GLenum specifying the binding point (target) for the framebuffer. 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.

attachment: A GLenum specifying the attachment point for the render buffer. Possible values:

gl.COLOR_ATTACHMENT0

color buffer.
gl.DEPTH_ATTACHMENT: depth buffer.
gl.DEPTH_STENCIL_ATTACHMENT: depth and stencil buffer.
gl.STENCIL_ATTACHMENT: stencil buffer.
When using a WebGL 2 context, the following values are available additionally:

gl.COLOR_ATTACHMENT1 gl.COLOR_ATTACHMENT2 gl.COLOR_ATTACHMENT3 gl.COLOR_ATTACHMENT4 gl.COLOR_ATTACHMENT5 gl.COLOR_ATTACHMENT6 gl.COLOR_ATTACHMENT7 gl.COLOR_ATTACHMENT8 gl.COLOR_ATTACHMENT9 gl.COLOR_ATTACHMENT10 gl.COLOR_ATTACHMENT11 gl.COLOR_ATTACHMENT12 gl.COLOR_ATTACHMENT13 gl.COLOR_ATTACHMENT14 gl.COLOR_ATTACHMENT15

When using the WEBGL_draw_buffers extension

ext.COLOR_ATTACHMENT0_WEBGL (same as gl.COLOR_ATTACHMENT0) ext.COLOR_ATTACHMENT1_WEBGL ext.COLOR_ATTACHMENT2_WEBGL ext.COLOR_ATTACHMENT3_WEBGL ext.COLOR_ATTACHMENT4_WEBGL ext.COLOR_ATTACHMENT5_WEBGL ext.COLOR_ATTACHMENT6_WEBGL ext.COLOR_ATTACHMENT7_WEBGL ext.COLOR_ATTACHMENT8_WEBGL ext.COLOR_ATTACHMENT9_WEBGL ext.COLOR_ATTACHMENT10_WEBGL ext.COLOR_ATTACHMENT11_WEBGL ext.COLOR_ATTACHMENT12_WEBGL ext.COLOR_ATTACHMENT13_WEBGL ext.COLOR_ATTACHMENT14_WEBGL ext.COLOR_ATTACHMENT15_WEBGL

renderbuffertarget: A GLenum specifying the binding point (target) for the render buffer. Possible values:

gl.RENDERBUFFER

Buffer data storage for single images in a renderable internal format.

renderbuffer: A WebGLRenderbuffer object to attach.

Return value

None.

Exceptions

A gl.INVALID_ENUM error is thrown if target is not gl.FRAMEBUFFER, gl.DRAW_FRAMEBUFFER, or gl.READ_FRAMEBUFFER.
A gl.INVALID_ENUM error is thrown if renderbuffertarget is not gl.RENDERBUFFER.
A gl.INVALID_ENUM error is thrown if attachment is not one of the allowed enums.

Examples

gl.framebufferRenderbuffer(gl.FRAMEBUFFER, gl.COLOR_ATTACHMENT0, gl.RENDERBUFFER, renderbuffer);
