target
Specifies the target to which the framebuffer is bound
for all commands except
glNamedFramebufferTexture
.
framebuffer
Specifies the name of the framebuffer object for
glNamedFramebufferTexture
.
attachment
Specifies the attachment point of the framebuffer.
textarget
For glFramebufferTexture1D
,
glFramebufferTexture2D
and
glFramebufferTexture3D
, specifies
what type of texture is expected in the
texture
parameter, or for cube
map textures, which face is to be attached.
texture
Specifies the name of an existing texture object to attach.
level
Specifies the mipmap level of the texture object to attach.
These commands attach a selected mipmap level or image of a texture object as one of the logical buffers of the specified framebuffer object. Textures cannot be attached to the default draw and read framebuffer, so they are not valid targets of these commands.
For all commands except
glNamedFramebufferTexture
, 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 glNamedFramebufferTexture
,
framebuffer
is the name of the
framebuffer object.
attachment
specifies the logical
attachment of the framebuffer and must be
GL_COLOR_ATTACHMENT
i,
GL_DEPTH_ATTACHMENT
,
GL_STENCIL_ATTACHMENT
or
GL_DEPTH_STENCIL_ATTACHMENT
.
i in
GL_COLOR_ATTACHMENT
i
may range from zero to the value of
GL_MAX_COLOR_ATTACHMENTS
minus one.
Attaching a level of a texture to
GL_DEPTH_STENCIL_ATTACHMENT
is equivalent
to attaching that level to both the
GL_DEPTH_ATTACHMENT
and the
GL_STENCIL_ATTACHMENT
attachment points
simultaneously.
For glFramebufferTexture1D
,
glFramebufferTexture2D
and
glFramebufferTexture3D
,
textarget
specifies what type of texture
is named by texture
, and for cube map
textures, specifies the face that is to be attached. If
texture
is not zero, it must be the name
of an existing texture object with effective target
textarget
unless it is a cube map
texture, in which case textarget
must be
GL_TEXTURE_CUBE_MAP_POSITIVE_X
GL_TEXTURE_CUBE_MAP_NEGATIVE_X
,
GL_TEXTURE_CUBE_MAP_POSITIVE_Y
,
GL_TEXTURE_CUBE_MAP_NEGATIVE_Y
,
GL_TEXTURE_CUBE_MAP_POSITIVE_Z
, or
GL_TEXTURE_CUBE_MAP_NEGATIVE_Z
.
If texture
is non-zero, the specified
level
of the texture object named
texture
is attached to the framebfufer
attachment point named by attachment
. For
glFramebufferTexture1D
,
glFramebufferTexture2D
, and
glFramebufferTexture3D
,
texture
must be zero or the name of an
existing texture with an effective target of
textarget
, or
texture
must be the name of an existing
cube-map texture and textarget
must be
one of GL_TEXTURE_CUBE_MAP_POSITIVE_X
,
GL_TEXTURE_CUBE_MAP_POSITIVE_Y
,
GL_TEXTURE_CUBE_MAP_POSITIVE_Z
,
GL_TEXTURE_CUBE_MAP_NEGATIVE_X
,
GL_TEXTURE_CUBE_MAP_NEGATIVE_Y
, or
GL_TEXTURE_CUBE_MAP_NEGATIVE_Z
.
If textarget
is
GL_TEXTURE_RECTANGLE
,
GL_TEXTURE_2D_MULTISAMPLE
, or
GL_TEXTURE_2D_MULTISAMPLE_ARRAY
, then
level
must be zero.
If textarget
is
GL_TEXTURE_3D
, then
level
must be greater than or equal to
zero and less than or equal to $log_2$ of the value of
GL_MAX_3D_TEXTURE_SIZE
.
If textarget
is one of
GL_TEXTURE_CUBE_MAP_POSITIVE_X
,
GL_TEXTURE_CUBE_MAP_POSITIVE_Y
,
GL_TEXTURE_CUBE_MAP_POSITIVE_Z
,
GL_TEXTURE_CUBE_MAP_NEGATIVE_X
,
GL_TEXTURE_CUBE_MAP_NEGATIVE_Y
, or
GL_TEXTURE_CUBE_MAP_NEGATIVE_Z
, then
level
must be greater than or equal to
zero and less than or equal to $log_2$ of the value of
GL_MAX_CUBE_MAP_TEXTURE_SIZE
.
For all other values of textarget
,
level
must be greater than or equal to
zero and less than or equal to $log_2$ of the value of
GL_MAX_TEXTURE_SIZE
.
layer
specifies the layer of a
2-dimensional image within a 3-dimensional texture.
For glFramebufferTexture1D
, if
texture
is not zero, then
textarget
must be
GL_TEXTURE_1D
. For
glFramebufferTexture2D
, if
texture
is not zero,
textarget
must be one of
GL_TEXTURE_2D
,
GL_TEXTURE_RECTANGLE
,
GL_TEXTURE_CUBE_MAP_POSITIVE_X
,
GL_TEXTURE_CUBE_MAP_POSITIVE_Y
,
GL_TEXTURE_CUBE_MAP_POSITIVE_Z
,
GL_TEXTURE_CUBE_MAP_NEGATIVE_X
,
GL_TEXTURE_CUBE_MAP_NEGATIVE_Y
,
GL_TEXTURE_CUBE_MAP_NEGATIVE_Z
, or
GL_TEXTURE_2D_MULTISAMPLE
. For
glFramebufferTexture3D
, if
texture
is not zero, then
textarget
must be
GL_TEXTURE_3D
.
For glFramebufferTexture
and
glNamedFramebufferTexture
, if
texture
is the name of a
three-dimensional, cube map array, cube map, one- or
two-dimensional array, or two-dimensional multisample array
texture, the specified texture level is an array of images, and
the framebuffer attachment is considered to be
layered.
GL_INVALID_ENUM
is generated by all
commands accepting a target
parameter if
it is not one of the accepted framebuffer targets.
GL_INVALID_OPERATION
is generated by all
commands accepting a target
parameter if
zero is bound to that target.
GL_INVALID_OPERATION
is generated by
glNamedFramebufferTexture
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_VALUE
is generated if
texture
is not zero or the name of an
existing texture object.
GL_INVALID_VALUE
is generated if
texture
is not zero and
level
is not a supported texture level
for texture
.
GL_INVALID_VALUE
is generated by
glFramebufferTexture3D
if
texture
is not zero and
layer
is larger than the value of
GL_MAX_3D_TEXTURE_SIZE
minus one.
GL_INVALID_OPERATION
is generated by all
commands accepting a textarget
parameter
if texture
is not zero, and
textarget
and the effective target of
texture
are not compatible.
GL_INVALID_OPERATION
is generated by
if texture
is a buffer texture.
