Detailed Description

template<typename Vreg, typename Vpts, typename Indx = unsigned int>
class regionD2tess< Vreg, Vpts, Indx >

Tessellation of linked regions.

vi and pts are vectors.

Through the template parameters the client can control memory of the vectors, for example Vreg could be a vector holding the regions and Vpts a reference to the points.
