[vtkusers] About vtkIterativeClosestPointTransform

[Yang Shen]

Hi,

I am trying to use vtkIterativeClosestPointTransform, but an error
(Unhandled exception at 0x009daa20 in Registration.exe: 0xC0000005: Access
violation reading location 0xeab7c030.) occurs when method Update() of this
class is called.

I don't know how to deal with this problem. Is there any thing I have
missed? Any help will be appreciated.

PS. The code fragment:
...
vtkIterativeClosestPointTransform *icp =
vtkIterativeClosestPointTransform::New();

icp->SetSource(data1);
icp->SetTarget(data2);
icp->SetCheckMeanDistance(true);
icp->SetMaximumMeanDistance(0.001);
icp->SetMaximumNumberOfIterations(3000);
icp->SetMaximumNumberOfLandmarks(800);
icp->StartByMatchingCentroidsOff();

icp->Update(); // a memory error occurs here

...
