This work describes implementation tips and notices to implement the robust epsilon visibility skeleton. Implementation details of robust epsilon visibility paper in Siggraph 2002 are detailed in this document with a review of previous work.

In this work, we extend the visibility skeleton to be robust on calculation precision errors using robust hit predicates. This results in higher number of degenerate configurations and a better support for small and sliver edges and complex scenes.
