HydroCouple::Spatial::IEdge Class Referenceabstract

A directed edge from one vertex to another, adjacent to two faces. Based on Dani Lischinski's code from Graphics Gems IV. Original quad-edge data structure due to Guibas and Stolfi (1985). Does not inherit from geometry to reduce size. since each edge has 4 pointers. More...

Detailed Description

A directed edge from one vertex to another, adjacent to two faces. Based on Dani Lischinski's code from Graphics Gems IV. Original quad-edge data structure due to Guibas and Stolfi (1985). Does not inherit from geometry to reduce size. since each edge has 4 pointers.
