If different colors for the building elements roof, wall and ground surfaces shall be used, we need to have different shape for these elements. However, they can share the same point set. The following example uses different Material for roof, wall, and ground surfaces. <br> <pre> <code class="language-html"><html> <head><title> indexed face set and material </title> <script type='text/javascript' src='http://www.x3dom.org/download/x3dom.js'> </script> <link rel='stylesheet' type='text/css' href='http://www.x3dom.org/download/x3dom.css'></link> </head> <body>
