44    <div class="section">
45<p>Sets vertex attributes using <code>GLfloat</code>-type values.</p><P>
46Set <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>.
47            </P><P>
48The value specified by <span class="argument">x</span> is given as the x component to the vertex shader's input registers. Values of 0, 0, and 1 are respectively given for y, z, and w.
