<h2>Description</h2>

<p><code class="function">glBindTextureUnit</code> binds an existing texture object to the texture unit numbered <em class="parameter"><code>unit</code></em>.</p>

<p><em class="parameter"><code>texture</code></em> must be zero or the name of an existing texture object. When <em class="parameter"><code>texture</code></em> is the name of an existing texture object, that object is bound to the target, in the corresponding texture unit, that was specified when the object was created. When <em class="parameter"><code>texture</code></em> is zero, each of the targets enumerated at the beginning of this section is reset to its default texture for the corresponding texture image unit. </p>
