I find that `vtkPropPicker` can set the `vtkPropCollection` for pick:
```auto
int PickProp(
double selectionX, double selectionY, vtkRenderer* renderer, vtkPropCollection* pickfrom);
```
This function allows to pick from the specificed prop.
Is it possible to set `vtkPropCollection` for `vtkCellPicker`?
Any suggestion is appreciated~~~

I believe this will work: vtkCellPicker is a derived class of vtkAbstractPicker. As such, it has methods like AddPickList(vtkProp\*) and PickFromListOn(). If you have a list of props to pick, turn on PickFronListOn() and add them to the cell picker etc. and perform the pick.

Thank you very much, it works~~~
