Detailed Description
The Constraint is really a cone on the skysphere.
It is characterized by its direction a_, the opening angle s_ and its cosine – the distance of the plane intersecting the sphere and the sphere center. If d_ = 0, we have a halfsphere. If it is negative, we have a 'hole' i.e. the room angle is larger than 90degrees.
Example: positive distance
____   / /\ / / =\  / == this side is in the convex.  /\s ===  > direction a  \ ===  \ == \ \ =/ \ \/ ____ <d> is positive (s < 90)
Example: negative distance
____ ==== this side is /========/\ in the /========/= \ convex ==== s__/==  ===== / /===  dir. a <  'hole' in the sphere ========\===  ========\==  \========\= / \========\/ ____ <d> is negative (s > 90)
for d=0 we have a halfsphere. Combining such, we get triangles, rectangles etc on the sphere surface (pure ZERO convexes)
