[vtkusers] Re: Checking whether a coordinate is already in vtkPoints

[Wesley Brooks]

Thanks for your help Anja,

Store a map? I'm working on python at the moment and my current bodge is to
store an additional python list with the points in it and check against this
list, this seems a little wasteful on memory. I guess this isn't what you
mean?

Cheers,

Wesley Brooks.
