Hi!<br>I need to cast my Point Data to a vtkDoubleArray, but it fails:<br><br>vtkPointData *scaldat = input -> GetPointData();<br>vtkDoubleArray *scalars = vtkDoubleArray::New();<br>scalars = vtkDoubleArray::SafeDownCast(scaldat); <br>if(!scalars) vtkErrorMacro("SafeDownCast to vtkDoubleArray failed");<br><br>and everytime I run the program I get that vtkErrorMacro. <br>as far as I know from the input files, the PointData should be float, but casting to vtkFloatArray fails as well. Why? and what can I do about it?<br><br>thx a lot,<br>NH<br><br /><hr />Express yourself instantly with MSN Messenger! <a href='http://clk.atdmt.com/AVE/go/onm00200471ave/direct/01/' target='_new'>MSN Messenger</a></body>
