[Paraview] Toggling between 2D & 3D view Issue

[komeil]

Dear friends,

 

here is my implementation for having 2D view along with 3D view for Volume
Rendeing:

 

$("#view_3d").bind("mousedown", function(){

                                  if ($(this).hasClass("session_started")) {

 
pv.connection.session.call('vtk:load3DView', null);

                                                return false;

       }else{

                                 $(this).addClass("session_started");

                                  create3DView("#view_3d);


 
pv.connection.session.call('vtk:save3DView', null);

                }              

 

$(UI_AXIAL).bind("mouseup", function(){

                                pv.connection.session.call('vtk:save3DView',
null);

});

 

I have the similar code for 2D. There are 2 viewports created to show loaded
volume:

 

pv.viewport_3D = vtkWeb.createViewport({

                                                                session:
pv.connection.session

                                                });

 
pv.viewport_3D.bind("#view_3d");

 

and same code for 2D.

 

By clicking on each view, RPC function 'vtk:save3DView' or 'vtk:save2DView'
will be called. Each one changes the display properties & render view for
representing appropriate view. For example for loading 3D:

 

                dp.Representation = 'Volume'

                view = simple.GetRenderView()

                view.InteractionMode = '3D'

 

I can expect that it takes time to render the scene when the user clicks on
the other view, especially changing from 2D to 3D.

But, the issue is by clicking on the other view, the last view is shown
before the completion of the rendering. For instance, if the current view is
2D, and user clicks on 3D, immediately, the last 2D scene is displayed in 3D
view for a while, before having the rendered 3D view from the server.

 

My question is how to prevent system to show the 2D view in 3D view, and
just wait for the server to send rendered 3D scene.
