The WebGLRenderingContext.framebufferRenderbuffer()
method of the WebGL API attaches a WebGLRenderbuffer
object to a WebGLFramebuffer
object.
The WebGLRenderingContext.framebufferRenderbuffer()
method of the WebGL API attaches a WebGLRenderbuffer
object to a WebGLFramebuffer
object.
js
framebufferRenderbuffer(target, attachment, renderbuffertarget, renderbuffer)
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.
None (undefined
).
gl.INVALID_ENUM
error is thrown if target
is not gl.FRAMEBUFFER
, gl.DRAW_FRAMEBUFFER
, or gl.READ_FRAMEBUFFER
. gl.INVALID_ENUM
error is thrown if renderbuffertarget
is not gl.RENDERBUFFER
. gl.INVALID_ENUM
error is thrown if attachment
is not one of the allowed enums. js
gl.framebufferRenderbuffer( gl.FRAMEBUFFER, gl.COLOR_ATTACHMENT0, gl.RENDERBUFFER, renderbuffer, );
