[vtkusers] vtkPointSet::GetPoint bug?

[David Doria]

One of the functions for getting a point from a PolyData (actually the
PointSet) doesn't seem to work (or I am doing something wrong)

This one works fine:
1) void GetPoint<http://www.vtk.org/doc/nightly/html/classvtkPointSet.html#ef4cdb2893d13d2b4b9c61a4848f1e50>(
vtkIdType<http://www.vtk.org/doc/nightly/html/vtkType_8h.html#20bd6b6dedfe1bbb096c50354d52cc7e>ptId,
double x[3])

    double p0[3];
    TriPoints->GetPoint(0, p0);

This one seems to give the same values for GetPoint(0), GetPoint(1),
GetPoint(2).
2) double * GetPoint<http://www.vtk.org/doc/nightly/html/classvtkPointSet.html#7b1f11e85608a0de638810dbea9749ab>(
vtkIdType<http://www.vtk.org/doc/nightly/html/vtkType_8h.html#20bd6b6dedfe1bbb096c50354d52cc7e>ptId)

double* p0;
p0 = TriPoints->GetPoint(0);

Here is a compilable example:
http://www.rpi.edu/~doriad/VTK_List/GetPoint/GetPointTest.cpp<http://www.rpi.edu/%7Edoriad/VTK_List/GetPoint/GetPointTest.cpp>

This seems like a pretty basic function, so maybe I am just calling it
wrong?

Thanks,

David
