Voronoi diagrams and their dual tetrahedral structures are often utilized in various analyses of protein models where atoms are represented as balls. The additively weighted kind of Voronoi diagrams (aw-VD) is particularly useful in this area because it includes the variability of ball size. The dynamic behavior of proteins can be realistically modeled by a simulation of molecular dynamics recording atom positions at discrete snapshots of time. However, aw-VDs for these snapshots require a lot of storage. This is where domain-specific compression could help, but available algorithms are oriented primarily to the compression of ordinary tetrahedral meshes, not to aw-VDs whose dual tetrahedral structure may have anomalies complicating duality inversion and tetrahedral mesh traversal. Therefore, we propose a method that can compactly store the dual tetrahedral structure. The method is built on general ideas of an already known cut-border machine and improves these ideas in several ways so it can be applied to aw-VDs and perform well on protein data.
