<h2>Description</h2>

<p>

<code class="function">glFramebufferTexture2D</code> attaches a selected mipmap level or image of a texture object as one of the

logical buffers of the framebuffer object currently bound to <em class="parameter"><code>target</code></em>. <em class="parameter"><code>target</code></em> must

be <code class="constant">GL_DRAW_FRAMEBUFFER</code>, <code class="constant">GL_READ_FRAMEBUFFER</code>, or <code class="constant">GL_FRAMEBUFFER</code>.

<code class="constant">GL_FRAMEBUFFER</code> is equivalent to <code class="constant">GL_DRAW_FRAMEBUFFER</code>.

</p>

<p>

<em class="parameter"><code>attachment</code></em> specifies the logical attachment of the framebuffer and must be

<code class="constant">GL_COLOR_ATTACHMENT</code><span class="emphasis"><em>i</em></span>, <code class="constant">GL_DEPTH_ATTACHMENT</code>,

<code class="constant">GL_STENCIL_ATTACHMENT</code> or <code class="constant">GL_DEPTH_STENCIL_ATTACHMENT</code>.

<span class="emphasis"><em>i</em></span> in <code class="constant">GL_COLOR_ATTACHMENT</code><span class="emphasis"><em>i</em></span> may range from zero to

the value of <code class="constant">GL_MAX_COLOR_ATTACHMENTS</code> - 1. Attaching a level of a texture to

<code class="constant">GL_DEPTH_STENCIL_ATTACHMENT</code> is equivalent to attaching that level to both the

<code class="constant">GL_DEPTH_ATTACHMENT</code> <span class="emphasis"><em>and</em></span> the <code class="constant">GL_STENCIL_ATTACHMENT</code>

attachment points simultaneously.

</p>

<p>

<em class="parameter"><code>textarget</code></em> specifies what type of texture is named by <em class="parameter"><code>texture</code></em>, and for

cube map textures, specifies the face that is to be attached. If <em class="parameter"><code>texture</code></em> is not zero, it

must be the name of an existing two dimensional texture with <em class="parameter"><code>textarget</code></em> set to <code class="constant">GL_TEXTURE_2D</code>,

or an existing two dimensional multisample texture with <em class="parameter"><code>textarget</code></em> set to <code class="constant">GL_TEXTURE_2D_MULTISAMPLE</code>,

unless it is a cube map texture, in which case <em class="parameter"><code>textarget</code></em> must be

<code class="constant">GL_TEXTURE_CUBE_MAP_POSITIVE_X</code>

<code class="constant">GL_TEXTURE_CUBE_MAP_NEGATIVE_X</code>, <code class="constant">GL_TEXTURE_CUBE_MAP_POSITIVE_Y</code>,

<code class="constant">GL_TEXTURE_CUBE_MAP_NEGATIVE_Y</code>, <code class="constant">GL_TEXTURE_CUBE_MAP_POSITIVE_Z</code>, or

<code class="constant">GL_TEXTURE_CUBE_MAP_NEGATIVE_Z</code>.

</p>

<p>

If <em class="parameter"><code>texture</code></em> is non-zero, the specified <em class="parameter"><code>level</code></em> of the texture object named

<em class="parameter"><code>texture</code></em> is attached to the framebuffer attachment point named by <em class="parameter"><code>attachment</code></em>.

</p>

<p>

If <em class="parameter"><code>textarget</code></em> is one of <code class="constant">GL_TEXTURE_CUBE_MAP_POSITIVE_X</code>,

<code class="constant">GL_TEXTURE_CUBE_MAP_POSITIVE_Y</code>, <code class="constant">GL_TEXTURE_CUBE_MAP_POSITIVE_Z</code>,

<code class="constant">GL_TEXTURE_CUBE_MAP_NEGATIVE_X</code>, <code class="constant">GL_TEXTURE_CUBE_MAP_NEGATIVE_Y</code>,

or <code class="constant">GL_TEXTURE_CUBE_MAP_NEGATIVE_Z</code>, then <em class="parameter"><code>level</code></em> must be greater

than or equal to zero and less than or equal to log₂ of the value of

<code class="constant">GL_MAX_CUBE_MAP_TEXTURE_SIZE</code>. If <em class="parameter"><code>textarget</code></em> is <code class="constant">GL_TEXTURE_2D</code>,

<em class="parameter"><code>level</code></em> must be greater than or equal to zero and no larger than log₂

of the value of <code class="constant">GL_MAX_TEXTURE_SIZE</code>. If <em class="parameter"><code>textarget</code></em> is <code class="constant">GL_TEXTURE_2D_MULTISAMPLE</code>,

<em class="parameter"><code>level</code></em> must be equal to zero.

<h2>Errors</h2>
