Is it possible to visualize the point cloud in QVTKOpenGLWidget?

Hello,
@Paulo_Carvalho ,Thank you for your suggestion.

This sample point cloud has 397 points and real time point cloud has 57600 points. Now, I am testing with the bunny.pcd that has 397 point, but the program crashed. And I try the following VTK tutorials.

PointSource ,it render the point cloud without any error. But when I embed this render window to the Qt main window using QVTKOpenGLWidget , the program crashed after zoom or rotate the point cloud.

●I also try vtk-8.2.0/GUISupport/Qt/Testing/Cxx/TestQVTKOpenGLWidget.cxx and vtk-8.2.0/GUISupport/Qt/Testing/Cxx/TestQVTKOpenGLNativeWidget.cxx .

In TestQVTKOpenGLWidget ->Program crashed after interacting the window for about a few seconds.
In TestQVTKOpenGLNativeWidget → Nothing is displayed.
