«A vertex in a triangle mesh is called regular if its valence (i.e., its number of neighboring vertices) is 6 for interior vertices or 4 for boundary vertices. In quadrangle meshes, the regular valences are 4 and 3, respectively. [...] The global structure of a mesh can be classified as being irregular, semiregular, highly regular, or regular. [...] In a regular mesh all vertices are regular. A regular mesh can compactly be represented as a 2D array that can be used for efficient rendering (a so-called geometry image).»
