glFramebufferTextureLayer, glNamedFramebufferTextureLayer — attach a single layer of a texture object as a logical buffer of a framebuffer object
void glFramebufferTextureLayer( | GLenum target, |
GLenum attachment, | |
GLuint texture, | |
GLint level, | |
GLint layer) ; |
void glNamedFramebufferTextureLayer( | GLuint framebuffer, |
GLenum attachment, | |
GLuint texture, | |

GLint layer) ; |
target
Specifies the target to which the framebuffer is bound for glFramebufferTextureLayer
.
framebuffer
Specifies the name of the framebuffer object for glNamedFramebufferTextureLayer
.
attachment
Specifies the attachment point of the framebuffer.
texture
Specifies the name of an existing texture object to attach.
level
Specifies the mipmap level of the texture object to attach.
layer
Specifies the layer of the texture object to attach.
glFramebufferTextureLayer
and glNamedFramebufferTextureLayer
attach a single layer of a three-dimensional or array 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 glFramebufferTextureLayer
, 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 glNamedFramebufferTextureLayer
, 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.
If texture
is not zero, it must be the name of a three-dimensional, two-dimensional multisample array, one- or two-dimensional array, or cube map array texture.
If texture
is a three-dimensional texture, 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 texture
is a two-dimensional array texture, then 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
.
For cube map textures, layer
is translated into a cube map face according to $$ face = k \bmod 6. $$ For cube map array textures, layer
is translated into an array layer and face according to $$ layer = \left\lfloor { layer \over 6 } \right\rfloor$$ and $$ face = k \bmod 6. $$
GL_INVALID_ENUM
is generated by glFramebufferTexture
if target
is not one of the accepted framebuffer targets.
GL_INVALID_OPERATION
is generated by glFramebufferTexture
if zero is bound to 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_OPERATION
is generated if texture
is not zero and is not the name of an existing three-dimensional, two-dimensional multisample array, one- or two-dimensional array, cube map, or cube map array texture.
GL_INVALID_VALUE
is generated if texture
is not zero and level
is not a supported texture level for texture
, as described above.
GL_INVALID_VALUE
is generated if texture
is not zero and layer
is larger than the value of GL_MAX_3D_TEXTURE_SIZE
minus one (for three-dimensional texture objects), or larger than the value of GL_MAX_ARRAY_TEXTURE_LAYERS
minus one (for array texture objects).
GL_INVALID_VALUE
is generated if texture
is not zero and layer
is negative.
GL_INVALID_OPERATION
is generated by if texture
is a buffer texture.
