As far as ParaView is concerned, no there's not much more to it.
However if your OpenGL implementation doesn't support OpenGL 3.2
(released in 2009), then alas there's more work to get ParaView
working which could include building a newer version of Mesa. Not sure
if you have seen this blog [1], but that talks about how I got Mesa to
build with appropriate OpenGL renderer enabled. Things have gotten a
little better since then and the Docker script encapsulates that. The
moral of the story is get latest Mesa version and build it with
LLVM/Gallum support.
