Hi all,<br><br><br>I need to load a large data set, for example a VRML file (500MB), I&#39;m using the following code (C#), <span id="result_box" class="short_text" lang="en"><span style="" title="">may not be the best way</span></span>, with my data set it&#39;s not work, not show anything : <br>
<br>            // VRML Import<br>           vtkVRMLImporter importer = vtkVRMLImporter.New();<br><br>           OpenFileDialog dialog = new OpenFileDialog();<br>           dialog.Filter =<br>              &quot;VRML files (*.wrl)|*.wrl|All files (*.*)|*.*&quot;;<br>
           dialog.InitialDirectory = &quot;\\Desktop&quot;;<br><br>           dialog.Title = &quot;Select a text file&quot;;<br>           dialog.Multiselect = false;<br>          if (dialog.ShowDialog() != DialogResult.OK)<br>
          {<br>              return;<br>          }<br><br>           importer.SetFileName(dialog.FileName);<br>           importer.Read();<br>           importer.Update();<br>          <br>           //Convert to vtkDataSet<br>
           vtkDataSet pDataset;<br>           vtkActorCollection actors = importer.GetRenderer().GetActors();<br>           actors.InitTraversal();<br>           pDataset = actors.GetNextActor().GetMapper().GetInput();<br>
          <br>           //Convert to vtkPolyData<br>           vtkPolyData polyData = vtkPolyData.SafeDownCast ( pDataset );<br>           polyData.Update();<br>          <br>           // Mapper<br>           vtkPolyDataMapper solidMapper = vtkPolyDataMapper.New();<br>
           solidMapper.SetInput ( polyData );<br>           solidMapper.ScalarVisibilityOff();<br>          <br>           // Actor<br>           vtkActor solidActor = vtkActor.New();<br>           solidActor.SetMapper ( solidMapper );<br>
<br>           //Add the actors to the scene<br>           _renderer.AddActor(solidActor);<br>           _renderer.SetBackground(1, 1, 1); // Background color dark blue<br><br>
