We construct random dynamics on collections of non-intersecting planar contours, leaving invariant the distributions of lengthand area-interacting polygonal Markov fields with V-shaped nodes. The first of these dynamics is based on the dynamic construction of consistent polygonal fields, as presented in the original articles by Arak (1982) and Arak & Surgailis (1989, 1991), and it provides an e...
