Description
I want to add image near 3d model.
I got pcl::visualization::PCLVisualizer,and QVTKOpenGLWidget.
I didnt find way to add 2d image to scene in pcl(there is
pcl::visualization::ImageViewer, but then i need to set another
visualizator, and the model displayed before that - dissapear).
I found that pcl::visualization::PCLVisualizer got method
getShapeActorMap().
Questions:
-Could i add something like vtkImageSlice, whether it will be displayed?
-Could u give me some example how to emplace vtkImageSlice to ShapeActorMap?
If this approach is stupid and does not make sense, please let me know.
I will be glad to any help.

Research direction
Start by reading the PCLVisualizer and ImageViewer integration points used with QVTKOpenGLWidget, including getShapeActorMap(). Check whether vtkImageSlice is supported in the existing visualization scene and compare it with the separate ImageViewer approach. Done means documenting a working combined-view example or confirming that the requested integration is unsupported.
