49<h2>Description</h2>
50    <div class="section">
51<p>Sets vertex attributes using <code>GLfloat</code>-type values.</p><P>
52Set <span class="argument">index</span> to a value that is greater than 0 and at least one less than the value that can be obtained by <code>glGetIntegerv</code> with <code>GL_MAX_VERTEX_ATTRIBS</code> specified. Call this function when using the same vertex attribute values for all vertices. The values set by this function are used when a vertex attribute array has been disabled by <code>glDisableVertexAttribArray</code>.

54            </P><P>
55The values specified by <span class="argument">x</span> and <span class="argument">y</span> are given as the x and y components, respectively, to the vertex shader's input registers. Values of 0 and 1 are respectively given for z and w.
56            </P><P>
