   <p>Now, this might look odd as it seems that we can specify more attribute kinds in our vertex format than we can in the vertex shader. However, in the shader <i>Position</i> and <i>3D Position</i> are treated as the <em>same </em>attribute, except that <i>Position</i> is expected to have only &quot;x&quot; and &quot;y&quot; coordinates whereas <i>3D Position</i> has “x”, “y” and “z” coordinates. So how do you map what&#39;s in your vertex format to how you define attributes in your shader? Let&#39;s start by looking at a typical set of attributes from the default shader:</p>
