[vtkusers] delete a cell (or point)

[Bill Chivas]

Hello all,

is there an efficient way to delete an element from a grid? One could say "just rebuild a new grid with the rest of the cells".
Imagine i have a very large grid, for example 5 million cells. It's very inefficient. 
So, is there any other way to delete a cell (or a point) from a grid apart from building a new grid with the remaining cells (or points)?
If not, any tricks for optimization the current "solution" of re-building the grid?

Thanks
