I have more information on the subject, but I’m still not entirely sure what the problem is exactly.
I’ve tried the StreamingParticles plugin and its RandomStreamingPoints source module. When I run it with lots of particles, I get the same error (Server Disconnected!), but this time it’s more explicit about it:
( 822.184s) [paraview ] vtkOutputWindow.cxx:78 ERR| ERROR: In vtkTextureObject.cxx, line 1028
vtkTextureObject (0x18cb18b0): Attempt to use a texture buffer exceeding your hardware's limits. This can happen when trying to color by cell data with a large dataset. Hardware limit is 134217728 values while 249999993 was requested.
I’ve looked into the problem and found a couple of threads about it: Paraview texture buffer size (or driver) issue and Texture buffer size error, both threads answered by @cory.quammen . I’m using ParaView 5.11.0 (which 5.12 seems recommended), and also my OpenGL Mesa versiones are 21.2.1 in my server side but 20.0.8 in my client side (which +21.1 seems recommended). However, even though this plugin needs to be loaded on both the server and client, mine in particular does not, so I don’t know if the Mesa version on my client side would have any influence.
Still, I don’t know if I’m in the correct path.
