Gl.FramebufferRenderbufferEXT (gb.opengl)
Static Sub FramebufferRenderbufferEXT ( Target As Integer, Attachment As Integer, RenderbufferTarget As Integer, Renderbuffer As Integer )
Attach a renderbuffer as a logical buffer to the currently bound framebuffer object.
Parameters
- target
-
Specifies the framebuffer target. target must be Gl.DRAW_FRAMEBUFFER,
Gl.READ_FRAMEBUFFER, or Gl.FRAMEBUFFER. Gl.FRAMEBUFFER
is equivalent to Gl.DRAW_FRAMEBUFFER.
- attachment
-
Specifies the attachment point of the framebuffer.
- renderbuffertarget
-
Specifies the renderbuffer target and must be Gl.RENDERBUFFER.
- renderbuffer
-
Specifies the name of an existing renderbuffer object of type renderbuffertarget to attach.
Description
Gl.FramebufferRenderbuffer attaches a renderbuffer as one of the logical buffers of the
currently bound framebuffer object.
renderbuffer is the name of the renderbuffer object
to attach and must be either zero, or the name of an existing renderbuffer object of type
renderbuffertarget.
If
renderbuffer is not zero and if
Gl.FramebufferRenderbuffer is
successful, then the renderbuffer name
renderbuffer will be used as the logical buffer
identified by
attachment of the framebuffer currently bound to
target.
The value of Gl.FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE for the specified attachment point is
set to Gl.RENDERBUFFER and the value of Gl.FRAMEBUFFER_ATTACHMENT_OBJECT_NAME
is set to
renderbuffer. All other state values of the attachment point specified by
attachment are set to their default values. No change is made to the state of the renderbuuffer
object and any previous attachment to the
attachment logical buffer of the framebuffer
target is broken.
Calling
Gl.FramebufferRenderbuffer with the renderbuffer name zero will detach the image, if any,
identified by
attachment, in the framebuffer currently bound to
target.
All state values of the attachment point specified by attachment in the object bound to target are set to their default values.
Setting
attachment to the value Gl.DEPTH_STENCIL_ATTACHMENT is a special
case causing both the depth and stencil attachments of the framebuffer object to be set to
renderbuffer,
which should have the base internal format Gl.DEPTH_STENCIL.
Errors
Gl.INVALID_ENUM is generated if
target is not one of the accepted tokens.
Gl.INVALID_ENUM is generated if
renderbuffertarget is not Gl.RENDERBUFFER.
Gl.INVALID_OPERATION is generated if zero is bound to
target.
