.SH "DESCRIPTION"
.PP
\fBglFramebufferTextureLayer\fR
and
\fBglNamedFramebufferTextureLayer\fR
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\&.
.PP
For
\fBglFramebufferTextureLayer\fR, the framebuffer object is that bound to
\fItarget\fR, which must be
\fBGL_DRAW_FRAMEBUFFER\fR,
\fBGL_READ_FRAMEBUFFER\fR, or
\fBGL_FRAMEBUFFER\fR\&.
\fBGL_FRAMEBUFFER\fR
is equivalent to
\fBGL_DRAW_FRAMEBUFFER\fR\&.
.PP
For
\fBglNamedFramebufferTextureLayer\fR,
\fIframebuffer\fR
is the name of the framebuffer object\&.
.PP
\fIattachment\fR
specifies the logical attachment of the framebuffer and must be
\fBGL_COLOR_ATTACHMENT\fR\fIi\fR,
\fBGL_DEPTH_ATTACHMENT\fR,
\fBGL_STENCIL_ATTACHMENT\fR
or
\fBGL_DEPTH_STENCIL_ATTACHMENT\fR\&.
\fIi\fR
in
\fBGL_COLOR_ATTACHMENT\fR\fIi\fR
may range from zero to the value of
\fBGL_MAX_COLOR_ATTACHMENTS\fR
minus one\&. Attaching a level of a texture to
\fBGL_DEPTH_STENCIL_ATTACHMENT\fR
is equivalent to attaching that level to both the
\fBGL_DEPTH_ATTACHMENT\fR
\fIand\fR
the
\fBGL_STENCIL_ATTACHMENT\fR
attachment points simultaneously\&.
.PP
If
\fItexture\fR
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\&.
.PP
If
\fItexture\fR
is a three\-dimensional texture, then
\fIlevel\fR
must be greater than or equal to zero and less than or equal to $log_2$ of the value of
\fBGL_MAX_3D_TEXTURE_SIZE\fR\&.
.PP
If
\fItexture\fR
is a two\-dimensional array texture, then
\fIlevel\fR
must be greater than or equal to zero and less than or equal to $log_2$ of the value of
\fBGL_MAX_TEXTURE_SIZE\fR\&.
.PP
For cube map textures,
\fIlayer\fR
is translated into a cube map face according to $$ face = k \ebmod 6\&. $$ For cube map array textures,
\fIlayer\fR
is translated into an array layer and face according to $$ layer = \eleft\elfloor { layer \eover 6 } \eright\erfloor$$ and $$ face = k \ebmod 6\&. $$
