<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi,<br><br>how to correctly generate a Points Global IDs to a vtkMultiBlockDataSet ? The IDs must, of course, be unique. I tried to iterate through the blocks and attribute to each part a vtkIntArray with the IDs, but of course this does not work when the parts have points in common. <br><br>Also, I'm specially interested in MultiBlock comming from Ensight files, and I discovered recently that the Ensight Reader does not associate the "true" number of points to each part. So the GetNumberOfPoints() method doesn't work in these cases.<br><br>How to achieve this ? I really need these Global IDs in order to uniquely identify each node of my model, to create a finite element preprocessor.<br><br>Regards,<br>Rafael March.<br><br><br></td></tr></table><br>
