<p>Hi Aron,<br>
</p>
<p><br>
</p>
<p>Sorry for interrupting you again. I'm learning how to use wslink in my project. My project is coded using previous vtkweb framework, and learn a lot from its simple example to display a cone on the browse. Now I would like to use wslink, which can support
python 3.x, to replace the old framework. I am not sure if you could provide me a similar simple example. Then I could learn by myself how to do that. Thanks in advance.</p>

<p>Hi all,<br>
</p>
<p><br>
</p>
<p>I found there probably be a bug around Line 250 in <VTK_build>/Wrapping/Python<wbr>/wslink/websocket.py. If this code is run using python 3.x, this will cause an error "json object must be str not 'bytes' " when use json.loads. To avoid this error, I think the
code can be modified by<br>
