One shape has only ony appearance. 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 roo, wall, and ground surfaces.
<X3D id="shapedata" width="600px" height="600px" style="float:left">
<Scene>
<Shape>
<!-- roof -->
<Appearance>
<Material diffuseColor="0.980, 0.502, 0.447"> </Material>
</Appearance>
<IndexedFaceSet solid="true" ccw ="true"
coordIndex=" 7 4 8 -1 4 5 8 -1 5 6 8 -1 6 7 8 -1">
<Coordinate DEF="pointset" point="-1 0 1, 1 0 1, 1 0 -1, -1 0 -1,

</IndexedFaceSet>
</Shape>
<Shape>
