[Paraview] The approach of Paraview's parallel rendering

[周恒众]

Thank you!
I know the paraview have the D3 filter , If I don't use the D3 filter , Does the paraview use the Icet to sort last ? I find that all nodes need to know  all the datas . In this situation , if sort-last, I think that every node  don't need all the datas , why should this?

ParaView uses IceT and does sort last compositing. ParaView gives IceT color and depth buffers from each node, IceT quickly gives us a depth composited image.


There are exceptions, but in general we do not do anything special with regards to load balancing. Rather, we read in the data in parallel and keep whatever partitioning scheme the simulation code that produced it wrote it in.

        Hello everyone . Recently, I do some research about parallel rendering . I want to know how paraview do the parallel rendering . Does it use sort last or sort first ,or both .
        I know it use IceT at last . If Icet is a sort last libaray , it should transfer the final pixel to the corresponding node , where  it do this . Or it is a sort first , so every node has all the datas ,and just render the datas corresponding to the screen .
        Also ,i want to know if paraview achieve the loading balance ,and how does this?
        who can tell me these ,thank you very much!
