NAME
glFramebufferRenderbuffer - attach a renderbuffer as a logical buffer
to the currently bound framebuffer object
C SPECIFICATION
void glFramebufferRenderbuffer(GLenum target, GLenum attachment,
GLenum renderbuffertarget,
GLuint renderbuffer);
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
glFramebufferRenderbuffer 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 glFramebufferRenderbuffer 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 glFramebufferRenderbuffer 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.
