glFramebufferRenderbuffer, glNamedFramebufferRenderbuffer — attach a renderbuffer as a logical buffer of a framebuffer object
void glFramebufferRenderbuffer(
|
GLenum target, |
| GLenum attachment, | |
| GLenum renderbuffertarget, | |
GLuint renderbuffer); |
void glNamedFramebufferRenderbuffer(
|
GLuint framebuffer, |
| GLenum attachment, | |
| GLenum renderbuffertarget, | |
GLuint renderbuffer); |
target
Specifies the target to which the framebuffer is bound
for glFramebufferRenderbuffer.
framebuffer
Specifies the name of the framebuffer object for
glNamedFramebufferRenderbuffer.
attachment
Specifies the attachment point of the framebuffer.
renderbuffertarget
Specifies the renderbuffer target. Must be
GL_RENDERBUFFER.
renderbuffer
Specifies the name of an existing renderbuffer object of
type renderbuffertarget to
attach.
glFramebufferRenderbuffer and
glNamedFramebufferRenderbuffer attaches a
renderbuffer as one of the logical buffers of the specified
framebuffer object. Renderbuffers cannot be attached to the
default draw and read framebuffer, so they are not valid targets
of these commands.
For glFramebufferRenderbuffer,
the framebuffer object is that bound to
target, which must be
GL_DRAW_FRAMEBUFFER,
GL_READ_FRAMEBUFFER or
GL_FRAMEBUFFER.
GL_FRAMEBUFFER is equivalent to
GL_DRAW_FRAMEBUFFER.
For glNamedFramebufferRenderbuffer,
framebuffer is the name of the
framebuffer object.
renderbuffertarget must be
GL_RENDERBUFFER.
renderbuffer must be zero or the name of
an existing renderbuffer object of type
renderbuffertarget. If
renderbuffer is not zero, then the
specified renderbuffer will be used as the logical buffer
identified by attachment of the specified
framebuffer object. If renderbuffer is
zero, then the value of
renderbuffertarget is ignored.
attachment specifies the logical
attachment of the framebuffer and must be
GL_COLOR_ATTACHMENTi,
GL_DEPTH_ATTACHMENT,
GL_STENCIL_ATTACHMENT or
GL_DEPTH_STENCIL_ATTACHMENT.
i in may range from zero to the value of
GL_MAX_COLOR_ATTACHMENTS minus one.
Setting attachment to the value
GL_DEPTH_STENCIL_ATTACHMENT is a special
case causing both the depth and stencil attachments of the
specified framebuffer object to be set to
renderbuffer, which should have the base
internal format GL_DEPTH_STENCIL.
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 specified attachment point 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
specified framebuffer object is broken.
If renderbuffer is zero, these commands
will detach the image, if any, identified by the specified
attachment point of the specified framebuffer object. All state
values of the attachment point are set to their default values.
GL_INVALID_ENUM is generated by
glFramebufferRenderbuffer if
target is not one of the accepted
framebuffer targets.
GL_INVALID_OPERATION is generated by
glFramebufferRenderbuffer if zero is bound
to target.
GL_INVALID_OPERATION is generated by
glNamedFramebufferRenderbuffer if
framebuffer is not the name of an
existing framebuffer object.
GL_INVALID_ENUM is generated if
attachment is not one of the accepted
attachment points.
GL_INVALID_ENUM is generated if
renderbuffertarget is not
GL_RENDERBUFFER.
GL_INVALID_OPERATION is generated if
renderbuffertarget is not zero or the
name of an existing renderbuffer object of type
GL_RENDERBUFFER.
