I found the bug:
SoDrawStyle should be added BEFORE (didn't know the order is
im****tant) the object is added to the scene:
> result->addChild(vertices);
> result->addChild(fs);
> result->addChild(sphere);
> result->addChild(drawStyle); <-- this line should be the first
> result->addChild(material);
