Are you referring to a specific family of triangulations (for example Delaunay)? If not, then every domain can be triangulated.

Hi,

I know that the infinite vertex in triangulations is used to generalize insertions of vertices without taking care about the location of the new vertex (inside / outside the domain). Are there any cases, where this kind of modelling fails, meaning that a triangulation of a domain cannot be represented?

I could imagine that some triangulations of concave domains cannot be represented. Does anybody know papers discussing those issues?

Thank you,

Daniel
