Comment(by novoselt):

 Indeed! I guess, I was going to return plain rays but either forgot, or
 changed my mind and then forgot ;-) Anyway, in this case it is already
 working as it should. The order may be different from the order of rays,
 but I am working on it.

 Can you also give a precise definition of adjacent cones of the same
 dimension? Should they be faces of a common cone of dimension one higher,
 or something else? Are there any subtle issues with non-complete fans?
