Dear paraview fellows, <br><br>I am trying to carry out a parallel rendering using paraview on our cluster. I got it almost running except for one issue: rendering of Text fails. Hopefully someone can advise me. <br><br>I followed the approach of the tuturial with the Sphere example (<a href="http://www.cscs.ch/fileadmin/user_upload/customers/users_entry_point/HORUS_Doc/PvPython.pdf">http://www.cscs.ch/fileadmin/user_upload/customers/users_entry_point/HORUS_Doc/PvPython.pdf</a>)<br>
<br>So I added the renderview and ProcessIdScalars to all the Show() commands, e.g.:<br><br><i>RenderView1 = sm.CreateRenderView()<br>SurfaceVectors1 = SurfaceVectors(SelectInputVectors = ['POINTS', 'U'])<br>
DataRepresentation5 = Show(ProcessIdScalars(SurfaceVectors1),RenderView1)<br></i><br>This works fine (also in parallel on 8 cores), except for the show of plain Text with Text<br><br>There I had to remove the ProcessIdScalars function, so I do:<br>
<br><br>t=Text(Text=timestr)<br>Show(t,RenderView1,Color=[0.0,0.0,0.0],Position=[0.01,0.95],FontSize=15)<br><br>Now it works, even if I run it on 1 core on the cluster. <br>However, if I run it on 8 cores, I get the error message<br>
<br><br><i>Process id: 0 >> ERROR: In /scratch/ParaView-3.8.1/VTK/Filtering/vtkDemandDrivenPipeline.cxx, line 827<br>vtkCompositeDataPipeline (0x5fc3b80): Input for connection index 0 on input port index 0 for algorithm vtkTransmitPolyDataPiece(0x5fc1ab0) is of type vtkTable, but a vtkPolyData is required.</i><br>
<br>Apperantly it is not allowed, it need information on the process Id I suppose. However, ProcessIdScalars does not work. Is there anybody who would know a solution?<br><br><br>
