       icetDataReplicationGroupColor -- define data replication.


       #include <GL/ice-t.h>

       void icetDataReplicationGroupColor(   GLint   color  );


       IceT  has  the  ability  to  take  advantage  of geometric data that is
       replicated among processes. If a group  of  processes  share  the  same
       geometry  data, then IceT will split the region of the display that the
       data projects onto among the  processes,  thereby  reducing  the  total
       amount of image composition work that needs to be done.

       Despite  the  name  of  the function, icetDataReplicationGroupColor has
       nothing to do the color of the data being replicated. Instead, color is
       used  to  mark  the  local  process  as  part  of  a given group.  When
       icetDataReplicationGroupColor is called, it finds all  other  processes
       that  have the same color and builds a group based on this information.

       icetDataReplicationGroupColor must be called on every processes  before
       the function will return.






       IceT  assumes  that  icetDataReplicationGroup  is called with the exact
       same parameters on all processes belonging to a given group.  Likewise,
       IceT  also  assumes that all processes have called icetBoundingVertices
       or icetBoundingBox with the exact  same  parameters  on  all  processes
       belonging  to  a  given  group.  These  requirements  are  not strictly
       enforced, but failing to do so may cause some of the geometry to not be

       make other man pages.
