[Paraview-developers] WG: endless loop in vtkOpenGLError

[Lodron, Gerald]

Here is the reduced example code for evaluation, please tell me if you can reproduce my issue (I am using the VTK libs of Paraview 4.1.0):

vtkContextView* poContextView = vtkContextView::New();
    poContextView->GetRenderer()->SetBackground(1.0, 1.0, 1.0);

    vtkChartXY* poChart = vtkChartXY::New();
    poChart->GetAxis(1)->SetTitle( "xaxis" );
    poChart->GetAxis(0)->SetTitle( "yaxis" );
    poChart->SetTitle( "Title" );

    poContextView->GetScene()->AddItem(poChart);

    // Create a poTable with some points in it...
    vtkTable* poTable = vtkTable::New();

    vtkSmartPointer<vtkDoubleArray> oXAxis = vtkSmartPointer<vtkDoubleArray>::New();
    oXAxis->SetName("xaxis");
        poTable->AddColumn(oXAxis);

    //poTable->AddColumn(oXAxis);

    vtkSmartPointer<vtkDoubleArray> oPositionlot = vtkSmartPointer<vtkDoubleArray>::New();

    oPositionlot->SetName( "Data0" );
    poTable->AddColumn(oPositionlot);


    poTable->SetNumberOfRows( 10 );

    poContextView->GetRenderWindow()->SetMultiSamples(0);

    poTable->GetColumn(0)->SetName("col1");
    for ( size_t nRow = 0; nRow < 10; ++nRow )
    {
        poTable->SetValue(nRow, 0, 1);
    }

    vtkPlot * poPlot = poChart->AddPlot(vtkChart::LINE);
    poPlot->SetInputData(poTable, 0, 0);
    //poPlot->SetInput(m_poTable, 0, nColumn);
    poPlot->SetColor( 1, 0, 0, 1 );
    poPlot->SetWidth( 1 );
    poPlot->GetPen()->SetLineType(1);

     poContextView->GetRenderer()->Render();
     poContextView->GetInteractor()->Initialize();
    poContextView->GetInteractor()->Start();

Betreff: [vtkusers] endless loop in vtkOpenGLError

Hi

I currently migrated my vtk code to vtk 6.1 and now have an endless loop in vtkClearOpenGLErrors at line 192 of vtkOpenGLError.h while using vtkContextView. This seems to be called in ClearLights of vtkOpenGLRenderer.cxx, any ideas, would be great!

Best regards
Gerald
