Hmmm, Isn't paraFoam just ParaView as packaged into the OpenFOAM distribution? If so, the next time OpenFOAM updates its version it should get ParaView 4.4 (along with whatever patches FOAM adds to it, like their version of the reader).
Regarding the new GL2 rendering, after ParaView 5.0 the new rendering work will be turned on by default. When paraFoam gets 5.0 the rendering will be faster but the readers will not be unaffected. As for the reader, when I briefly compared the code and history of the two readers several years ago I concluded that they were forks of each other. I.e. at some point they were the same thing, but have diverged over time. I don't know what specifically is different in the two branches. It would be great at some point we unified them and kept the best features of both. With a single source, maintenance and upgrades would be easier and there would be no confusion about the capabilities. cheers, David E DeMarle Kitware, Inc.
