Description
The current way of specifying geometry types is not satisfying. Using dimension-independent denominations like 'simplex' and 'cube' does indeed make the code dimension-independent. However, it also introduces several ambiguities for low-dimensional entities. Is a line a simplex or a cube? And what is a vertex?
I propose to use a small class to denote geometry types. Something like
template class NewGeometryType { // old geometry type GeometryType type;
bool isVertex();
bool isLine();
bool isSimplex();
[...]}
The new GeometryType can be used as the old one. But as it also contains the dimension, it can also answer questions like isVertex() as well.
