It was not my intention to model roofs, but a simple colorful roof also works with my addon

In the sourcecode of **THREEf.js** one can see, however, how the surfaces are designed in color.

```
function morphFaces( time ) { 
...
  if ( g.isGeometry ) {
 ...
 // g is the geometry! 
   g.faces[fIdx].materialIndex = g.materialCover( ( j + 0.5 ) / rs, i / hs, t ); // by function

...

  g.faces[fIdx].materialIndex = g.fixedMaterial[fixMatIdx][j1]; // overwrite by array
```
