I don't know why GetTuple is pure virtual in vtkDataArray . Though yeah I agree it should theoretically work the same way .<br><br>Darshan<br><br><div class="gmail_quote">On Sun, Aug 22, 2010 at 1:32 PM, David Doria <span dir="ltr"><<a href="mailto:daviddoria%2Bvtk@gmail.com">daviddoria+vtk@gmail.com</a>></span> wrote:<br>

David,<br><br>if you are using dataNormals then you can use GetComponent() function to retrieve the normals . This always returns double so you dont really need to know the type . But in case you want to make the class depending on type, I think you can switch using the GetDataTypeAsString function.<br>
<br>Darshan<br><br></blockquote><div> </div></div>Ah cool, GetComponent should do the trick. Is there a reason that there is not a function like</div><div class="gmail_quote"><br></div><div class="gmail_quote">void vtkDataArray::GetTuple(int i, double[3]) ?</div>
<div class="gmail_quote"><br></div><div class="gmail_quote">It is the same idea of always returning a double, but returning the casted values as an array. The components=3 specialization seems reasonable since vtkDoubleArray and vtkFloatArray both alread support it.</div>
