使用图形函数(vtk 6.1，Qt5.3，Ubuntu）时的分段错误

更新：调试信息

我正在从事Qt 5.3项目，需要在2D和3D坐标系中绘制数据。我一直在研究 vtk 6.1，因为它总体上看起来非常强大，我还需要在以后可视化图像数据。我在此示例中流畅地使用 Qvtkwidget

Qvtkwidget 示例

#include "mainwindow.h"
#include <QApplication>
#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL);
#include <vtkSmartPointer.h>
#include <vtkSphereSource.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkImageViewer.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkInteractorStyleImage.h>
#include <vtkRenderer.h>
#include <vtkJPEGReader.h>
#include <QVTKWidget.h>
int main(int argc, char** argv)
{
  QApplication app(argc, argv);
  QVTKWidget widget;
  widget.resize(256,256);
  // Setup sphere
  vtkSmartPointer<vtkSphereSource> sphereSource =
      vtkSmartPointer<vtkSphereSource>::New();
  sphereSource->Update();
  vtkSmartPointer<vtkPolyDataMapper> sphereMapper =
      vtkSmartPointer<vtkPolyDataMapper>::New();
  sphereMapper->SetInputConnection(sphereSource->GetOutputPort());
  vtkSmartPointer<vtkActor> sphereActor =
      vtkSmartPointer<vtkActor>::New();
  sphereActor->SetMapper(sphereMapper);
  // Setup window
  vtkSmartPointer<vtkRenderWindow> renderWindow =
      vtkSmartPointer<vtkRenderWindow>::New();
  // Setup renderer
  vtkSmartPointer<vtkRenderer> renderer =
      vtkSmartPointer<vtkRenderer>::New();
  renderWindow->AddRenderer(renderer);
  renderer->AddActor(sphereActor);
  renderer->ResetCamera();
  widget.SetRenderWindow(renderWindow);
  widget.show();
  app.exec();
  return EXIT_SUCCESS;
}

但是当我尝试实现图形示例（/Examples/Charts/Cxx/QChartTable.cxx）时，程序显示分段错误。

#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL)
#include "vtkFloatArray.h"
#include "vtkMath.h"
#include "vtkRenderer.h"
#include "vtkRenderWindow.h"
#include "vtkRenderWindowInteractor.h"
#include "vtkSmartPointer.h"
#include "vtkContextView.h"
#include "vtkContextScene.h"
#include "vtkChartXY.h"
#include "vtkPlot.h"
#include "vtkTable.h"
#include "vtkTimerLog.h"
#include <QApplication>
#include <QWidget>
#include <QMainWindow>
#include <QHBoxLayout>
#include "QVTKWidget.h"
#include "vtkQtTableView.h"
#define VTK_CREATE(type, name) 
  vtkSmartPointer<type> name = vtkSmartPointer<type>::New()
int main(int argc, char** argv)
{

  // Qt initialization
  QApplication app(argc, argv);
  QMainWindow mainWindow;
  mainWindow.setGeometry(0, 0, 1150, 600);
  // QVTK set up and initialization
  QVTKWidget *qvtkWidget = new QVTKWidget(&mainWindow);
  // Set up my 2D world...
  VTK_CREATE(vtkContextView, view); // This contains a chart object
  view->SetInteractor(qvtkWidget->GetInteractor());
  qvtkWidget->SetRenderWindow(view->GetRenderWindow());
  // Create a table with some points in it...
  VTK_CREATE(vtkTable, table);
  VTK_CREATE(vtkFloatArray, arrX);
  arrX->SetName("X Axis");
  table->AddColumn(arrX);
  VTK_CREATE(vtkFloatArray, arrC);
  arrC->SetName("Cosine");
  table->AddColumn(arrC);
  VTK_CREATE(vtkFloatArray, arrS);
  arrS->SetName("Sine");
  table->AddColumn(arrS);
  // Make a timer object - need to get some frame rates/render times
  VTK_CREATE(vtkTimerLog, timer);
  // Test charting with a few more points...
  int numPoints = 29;
  float inc = 7.0 / (numPoints-1);
  table->SetNumberOfRows(numPoints);
  for (int i = 0; i < numPoints; ++i)
    {
    table->SetValue(i, 0, i * inc);
    table->SetValue(i, 1, cos(i * inc) + 0.0);
    table->SetValue(i, 2, sin(i * inc) + 0.0);
    }
//   table->Update();
  // Add multiple line plots, setting the colors etc
  vtkSmartPointer<vtkChartXY> chart = vtkSmartPointer<vtkChartXY>::New();
  view->GetScene()->AddItem(chart);
  vtkPlot *line = chart->AddPlot(vtkChart::LINE);
  line->SetInputData(table, 0, 1);
  line->SetColor(255, 0, 0, 255);
  line = chart->AddPlot(vtkChart::LINE);
  line->SetInputData(table, 0, 2);
  line->SetColor(0, 255, 0, 255);
  line->SetWidth(2.0);
  // Instantiate a vtkQtChart and use that too
/*  vtkQtChart *qtChart = new vtkQtChart;
  chart = qtChart->chart();
  line = chart->AddPlot(vtkChart::LINE);
  line->SetTable(table, 0, 1);
  line->SetColor(255, 0, 0, 255);
  line = chart->AddPlot(vtkChart::LINE);
  line->SetTable(table, 0, 2);
  line->SetColor(0, 255, 0, 255);
  line->SetWidth(2.0);
*/
  // Now lets try to add a table view
  QWidget *widget = new QWidget(&mainWindow);
  QHBoxLayout *layout = new QHBoxLayout(widget);
  VTK_CREATE(vtkQtTableView, tableView);
  tableView->SetSplitMultiComponentColumns(true);
  tableView->AddRepresentationFromInput(table);
  tableView->Update();
  layout->addWidget(qvtkWidget, 2);
  //layout->addWidget(qtChart, 2);
  layout->addWidget(tableView->GetWidget());
  mainWindow.setCentralWidget(widget);
  // Now show the application and start the event loop
  mainWindow.show();
  return app.exec();
}

我不知道这个错误是如何发生的。

我已经在调试模式下重新编译了 VTK 并获得了更多调试信息。这是此程序的回溯。在此屏幕截图中，问题可能来自"this"指针"this"应该是vtkTextRenderer *，但"this"指向空指针。我认为这可能是 VTK 6.1 中的一个错误，但不知道如何修复它。请给我一些建议。谢谢

我是新手，仍然无法发布图片，所以我将其上传到此链接
