Good morning,
I have downloaded VCGParaView as a binary from the homepage of Heidelberg University. I need it from them because the program contains a vortex core detection filter plug in. After I start VCGParaView the following output messages appear:

I have no clue why the errors appear.
Can you please help me?

Looks like a specific issue with VCGParaView, not with ParaView. You may want to contact Heidelberg University about it.

Also the topic is targeting ParaView Web type of application which run in a Web browser.
