I would like to get a list of all the points that point A is connected to (via edges of a mesh - if a polydata with triangle cells can be interpreted like that?). It looks like I could call <a href="http://www.vtk.org/doc/release/4.0/html/classvtkPolyData.html#a36" target="_blank">BuildLinks</a> () and then <a href="http://www.vtk.org/doc/release/4.0/html/classvtkPolyData.html#a43" target="_blank">IsEdge</a> (A, int v2) where v2 would loop over all other points in the polydata and then collect all of the points which IsEdge returned true - but that seems horribly inefficient. I guess you could get the cell that the point belongs to, get the cell's neighbor cells, then test IsEdge with all of those cell's points - is this the best way to go? Can we add that idea (if it doesn't already exist and I'm missing it!) as a GetPointNeighbors() (following along, since GetCellNeighbors() already exists) to vtkPolyData?<br>
