ives with very few
        subroutine calls. You can prespecify separate arrays of
        vertices, normals, colors, and texture coordinates and use them
        to construct a sequence of primitives with a single call to
        <code class="function">glDrawArrays</code>.</p><p>When
        <code class="function">glDrawArrays</code> is called, it uses
        <em class="parameter"><code>count</code></em>
        sequential elements from each enabled array to construct a
        sequence of geometric primi
