I was able to use local rendering by first loading the data, then choosing a local rendering approach (either worked fine), and then going back and coloring by T. This could be a workaround if you need to test the speed of local rendering vs remote.</span></div><div><span style="color:rgb(0,0,0);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px"><br></span></div><div><span style="color:rgb(0,0,0);font-family:'Helvetica Neue',Helvetica,Arial,sans-serif;font-size:14px;line-height:20px">2) Regarding loading the .stl file, I did not run into the same issue as you did, i.e. the .stl file loaded without any problems.

When local rendering is enabled, the server's camera is still synchronized with with camera in the browser so that if you switch back to image delivery, you won't see some unexpected camera angle. If the network is *really* slow, this could perhaps keep the local rendering from being as fast as possible.

Maybe you could try to take one of the standard ParaView datasets and try to load it in ParaViewWeb, and see if you have the same issue you mentioned above. To get this data if you don't already have it, go here:</div><div><br clear="none"></div><div><a rel="nofollow" shape="rect" href="http://www.paraview.org/download/" target="_blank">http://www.paraview.org/download/</a><br clear="none"></div><div><br clear="none"></div><div>And under "Type of Download", choose "Data, Documentation, and Tutorials". Once you get this data, try opening the "disk_out_ref.ex2" file in ParaViewWeb. If you see the same issue as above, then there could be something going on with the way you have built ParaView, which we can try to figure out at that point. If you do not see the same issue as above, then perhaps you could send me (off the list) a sample data file I could use to try to replicate the problem and debug it on this end.</div><div><br clear="none"></div><div> </div><blockquote style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div><div style="color:rgb(0,0,0);font-family:HelveticaNeue,'Helvetica Neue',Helvetica,Arial,'Lucida Grande',sans-serif;font-size:13px;background-color:rgb(255,255,255)"><div><div><div style="font-family:HelveticaNeue,'Helvetica Neue',Helvetica,Arial,'Lucida Grande',sans-serif;font-size:13px;background-color:rgb(255,255,255)"><div dir="ltr" style="color:rgb(0,0,0)"></div><div style="color:rgb(0,0,0)"><br clear="none"></div><div style="color:rgb(0,0,0)"><b><u>Issue 2: </u></b></div><div style="color:rgb(0,0,0)"><br clear="none"></div><div dir="ltr">If I do the following selections on the ParaViewWeb, I always receive <span style="color:rgb(205,35,44)">src/VTK/Common/Core/vtkDataArrayTemplate.h:191: T vtkDataArrayTemplate<T>::GetValue(vtkIdType) [with T = float; vtkIdType = long long int]: Assertion `id >= 0 && id < this->Size' failed </span><span>message in the log file and cause the web socket connection closed. </span></div><div style="color:rgb(0,0,0)"><b><u><br clear="none"></u></b></div><div dir="ltr" style="color:rgb(0,0,0)"><img alt="Inline image" style="width: 100%; max-width: 800px; max-height: 372px;"><br clear="none"><b><u><br clear="none"></u></b></div><div style="color:rgb(0,0,0)"><br clear="none"></div><div style="color:rgb(0,0,0)"><b><u><br clear="none"></u></b></div><div style="color:rgb(0,0,0)"><br clear="none"></div><div style="color:rgb(0,0,0)"><font color="#cd232c">2015-09-23 17:33:52-0400 [-] Log opened.</font></div><div style="color:rgb(0,0,0)"><font color="#cd232c">2015-09-23 17:33:53-0400 [-] Site starting on 9009</font></div><div style="color:rgb(0,0,0)"><font color="#cd232c">2015-09-23 17:33:53-0400 [-] Starting factory <twisted.web.server.Site instance at 0x7fb6f2e55830></font></div><div style="color:rgb(0,0,0)"><font color="#cd232c">2015-09-23 17:33:53-0400 [HTTPChannel,0,127.0.0.1] Client has reconnected, cancelling reaper</font></div><div style="color:rgb(0,0,0)"><font color="#cd232c">2015-09-23 17:33:53-0400 [HTTPChannel,0,127.0.0.1] on_connect: connection count = 1</font></div><div dir="ltr" style="color:rgb(0,0,0)"><font color="#cd232c">pvpython: /home/user/ParaViewWeb/ParaView/src/VTK/Common/Core/vtkDataArrayTemplate.h:191: T vtkDataArrayTemplate<T>::GetValue(vtkIdType) [with T = float; vtkIdType = long long int]: Assertion `id >= 0 && id < this->Size' failed.</font></div><div style="color:rgb(0,0,0)"><br clear="none"></div><div style="color:rgb(0,0,0)">----------------------------------------------------------------------------------------------------------------------------------------------------------------</div><div style="color:rgb(0,0,0)"><br clear="none"></div><div><div dir="ltr"><font color="#cd232c">WebSocket connection to 'ws://XXXXXXXXXXX:8080/proxy?sessionId=0c562ad6-623f-11e5-9b44-00155dd73e0d' failed: Error during WebSocket handshake: Unexpected response code: 503</font><br clear="none"></div><div dir="ltr" style="color:rgb(0,0,0)"><br clear="none"></div></div><div style="color:rgb(0,0,0)"><br clear="none"></div><div dir="ltr" style="color:rgb(0,0,0)">I checked HTTP traffic, it has the following message.
