-\section{Analysis of 2D line space}
+This chapter provides analysis of the visibility in polygonal scenes,
+which are the input for all developed tools. The visibility analysis
+uncoveres the complexity of the from-region and global visibility
+problems and thus it especially important for a good design of the
+global visibility preprocessor. To better undestand the visibility
+relationships in primal space we use mapping to line space, where the
+visibility interactions can be observed easily by interactions of sets
+of points. Additionally for the sake of clarity, we first analyze
+visibility in 2D and then extend the analysis to 3D polygonal scenes.

+\section{Summary}
+
+ In this chapter we discussed the relation of sets of lines in 3D and
+the polyhedra in \plucker coordinates. We proposed a general size
+measure for a set of lines described by a blocker polyhedron and a
+size measure designed for the computation of PVS.
