Abstract
A roof over P is a 3D terrain such that every face has at
least one edge e of P on its boundary
and is supported by the half-plane above that intersects the ground at
angle 45 degree along the edge e.
In the talk we will investigate fundamental properties of roofs and 
an algorithm to enumerate roofs satisfying some conditions.
This is joint work with many participants of Korean workshop on
computational geometry 2004.
