[vtkusers] About vtkPoints::InsertPoint()

[Chris Wedlake]

x[3] is also not valid memory space which could be the issue.

Robert,

Hm, actually after reading the description:
http://www.vtk.org/doc/nightly/html/classvtkPoints.html#ab7f990c73fb291737abe4203994ce2a2

it sounds like what he was doing originally with InsertPoint(n,x) should work? I've never used this function, but it sounds like you would NOT have to call SetNumberOfPoints prior to using InsertPoint (unlike using SetPoint). Is that correct? If so, I guess Wenlong's originally question stands? Wenlong - can you make a minimal working example that demonstrates your problem on one OS and not the other?

David
