Abstract

  Net Juggler,  an open  source  library developed  at LIFO,  turns  a
commodity component  cluster running the  VR Juggler platform  on each
node into a single VR  Juggler image cluster. Net Juggler parallelizes
rendering  computations  for  immersive  projection  environments  but
pre-rendering computations  are redundant.  In this  paper, we present
how a classical parallelization  of the pre-rendering computations can
be  deployed  and  controlled  with  Net Juggler.   This  approach  is
demonstrated with an interactive fluid flow simulation.
