I have written some sample code that uses a vtkCellPicker with a vtkCellLocator. It is a simple modification of an existing VTK vtkCellPicker example. I did this because I could not find any examples anywhere of how to use a vtkCellPicker with a vtkCellLocator. With the locator, the picking is almost instantaneous. Should I post the code here or is there an existing example somewhere on a VTK site?
