<h2>Description</h2>
<p><code class="function">glVertexBindingDivisor</code> and
<code class="function">glVertexArrayBindingDivisor</code> modify the rate at which
generic vertex attributes advance when rendering multiple instances of
primitives in a single draw command. If <em class="parameter"><code>divisor</code></em> is
zero, the attributes using the buffer bound to
<em class="parameter"><code>bindingindex</code></em> advance once per vertex. If
<em class="parameter"><code>divisor</code></em> is non-zero, the attributes advance once
per <em class="parameter"><code>divisor</code></em> instances of the set(s) of vertices
being rendered. An attribute is referred to as
<span class="emphasis"><em>instanced</em></span> if the corresponding
<em class="parameter"><code>divisor</code></em> value is non-zero.</p>
<p><code class="function">glVertexBindingDivisor</code> uses currently bound
vertex array object , whereas
<code class="function">glVertexArrayBindingDivisor</code> updates state of the
vertex array object with ID <em class="parameter"><code>vaobj</code></em>.</p>
</div>
<div class="refsect1" id="errors">
<h2>Errors</h2>
<p><code class="constant">GL_INVALID_VALUE</code> is generated if
<em class="parameter"><code>bindingindex</code></em> is greater than or equal to the value
of <code class="constant">GL_MAX_VERTEX_ATTRIB_BINDINGS</code>.</p>
<p><code class="constant">GL_INVALID_OPERATION</code> by
<code class="function">glVertexBindingDivisor</code> is generated if no vertex
array object is bound.</p>
<p><code class="constant">GL_INVALID_OPERATION</code> is generated by
