| Foam::edgeSurface | |
| Description | |
| Description of surface in form of 'cloud of edges'. | |
| The 'cloud of edges': | |
| - points | |
| - edges | |
| - faceEdges | |
| - parentEdge (edge on surface this edge originates from) | |
| and nothing more. | |
| (pointEdges constructed from above data) | |
| Constructed from triSurface and surfaceIntersection. (uses localPoints | |
| of surface of course) | |
| Used to easily insert cuts and split faces. | |
| Note: | |
| - points with surface (local)points first, intersection points last | |
| - edges with (split) surface edges first, intersection edges last. | |
