<h2>Description</h2>

<p>

<code class="function">glFramebufferTextureLayer</code> operates like <a class="citerefentry" href="glFramebufferTexture2D"><span class="citerefentry"><span class="refentrytitle">glFramebufferTexture2D</span></span></a>,

except that only a single layer of the texture level, given by <em class="parameter"><code>layer</code></em>, is attached to the attachment point.

If <em class="parameter"><code>texture</code></em> is not zero, <em class="parameter"><code>layer</code></em> must be greater than or equal to zero.

<em class="parameter"><code>texture</code></em> must either be zero or the name of an existing three-dimensional texture, or a two-dimensional

array texture.

</p>

<p>

If <em class="parameter"><code>texture</code></em> is a 3D texture, 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_3D_TEXTURE_SIZE</code>. If <em class="parameter"><code>texture</code></em> is a 2D array texture,

<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>.

<p>

<code class="constant">GL_INVALID_ENUM</code> is generated if <em class="parameter"><code>attachment</code></em> is not one of the accepted tokens.
