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 togl.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.STENCIL_ATTACHMENT
: stencil buffer.- When using a WebGL 2 context, the following values are available additionally:
gl.DEPTH_STENCIL_ATTACHMENT
: depth and stencil buffer.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 asgl.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_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 iftarget
is notgl.FRAMEBUFFER
,gl.DRAW_FRAMEBUFFER
, orgl.READ_FRAMEBUFFER
. - A
gl.INVALID_ENUM
error is thrown ifrenderbuffertarget
is notgl.RENDERBUFFER
. - A
gl.INVALID_ENUM
error is thrown ifattachment
is not one of the allowed enums.
Examples
gl.framebufferRenderbuffer(gl.FRAMEBUFFER, gl.COLOR_ATTACHMENT0, gl.RENDERBUFFER, renderbuffer);
