Improve performance of vtkCellLocator

Hi All,

I found very frustrated using vtkCellLocator to find closest point when I have a very large vtk file. I was wondering is there any way to improve its performance. I was thinking in two directions: first, preprocess the vtk file into several parts, and second is probably using GPU parallel computing to speed up. Has anyone done this before or had any comments and suggestions? Thanks very much!
