Detailed Description

The Constraint is really a cone on the sky-sphere.

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 half-sphere. If it is negative, we have a 'hole' i.e. the room angle is larger than 90degrees.

Example: positive distance

.                ---____---.                     <-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 half-sphere. Combining such, we get triangles, rectangles etc on the sphere surface (pure ZERO convexes)
