-
- It may be called a tile, a polygon or polyhedron or polytope depending on the
- dimension, a Voronoi neighborhood, a Dirichlet region, or a Thiessen
- area-of-influence. Tesselations may be regular or irregular and based on any
- shape or collection of shapes that will fill space locally.
-
- |> qn.2 : Are there any other type of tesselations or equivalent terms ?
-
- A triangulation is a type of tesselation (sometimes tessellation) where all the
- tiles are triangles. A simplicial complex is a tesselation of simplices in
- any dimension. A Penrose tiling is a non-periodic tesselation of fixed shapes.

-
- Tesselations are used when spatial aggregates are considered. A common example
- concerns multivariate interpolation and one of the most general approaches to
- the generation of representative manifolds such as topographical surfaces uses
- the Voronoi tesselation as a basis for natural neighbor interpolation. We use
- that approach here for the study of chaotic behavior in higher dimensions.
-
- A classic reference for Voronoi tesslations and Delaunay triangulations is
- Rogers, C.A., 1964, Packing and covering, Cambridge University Press.
