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.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 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);
