This namespace controls how radii of atoms should be handled by the Shape TK when doing calculations. The default value of using the carbon radii approximation, OEOverlapRadii.Carbon, was found to have the best performance in virtual screening experiments.
Treat all heavy atoms, non-hydrogens, as carbon with the same radius.
The default approximation is OEOverlapRadii.Carbon, to treat all atoms as carbon.
The largest numerical value that can be contained in this namespace. Useful for being able to iterate over all the constants in this namespace.
