<div></div><div class="h5"><br><br><div>Hi Raj,<div><br></div><div>first of all you only need one session. A session is basically a dedicated connection to a ParaView server. So by creating 2 session, you were creating 2 server where you could have created 2 views in the same session and setup a mechanism to keep both camera of the views in synch.</div>
<div>Moreover, as you are using the same session, you can reuse your objects such as the LUT.</div><div>To keep object in synch, you will have to write some piece of code on the server side that you could call from your javascript client. </div>
<div>I don't have a simple example in mind but you could look at the pwsimple.py where I had some binding between the widget and the implicit functions that it represent. Of course the event type won't be the same but the idea is there. </div>
<div><br></div><div>In fact inside a Python plugin you should define a method like that:</div><div><br></div><div>def bindViews(view1, view2):</div><div> # add some python code to bind the two camera together</div><div>
# or maybe set the active camera of view1 to be the active</div><div> # camera of view 2.</div><div><br></div><div>I know that it does not give you the full answer but at least it give you some hints.</div><div><br>

<table border="0" cellpadding="0" cellspacing="0"><tbody><tr><td style="font:inherit" valign="top">Hi everyone<br> I would like to load two volume datasets (called FISH and SIMS in the code below) in ParaviewWeb and then render them side by side in two different views. The users should be able to 'lock' the camera amongst the two views so that moving the object in one window also affects the camera in the other. <br>
<br>I tried the following piece of code but ran into a error which made me think maybe I don't understand the concept of sessions and Display properties well. Hoping somebody could help shed some light. There are two functions that I've copy pasted below. Most of the variables are global for now and shared between the functions.<br>
