[vtkusers] vtkPoints + InsertPoint

[Bill Chivas]

Hi David,

try to put
 points->InsertPoint(60983688, 1, 2, 3);
 points->InsertPoint(60983689, 4, 5, 6);

and tell me the results.

In my last reply i just noted a bug (if it is one).
The problem i have is in the first post.

Can i use SmartPointer if it is a class variable?

Thanks,
Bill
