icetDataReplicationGroupColor(3)
NAME
icetDataReplicationGroupColor -- define data replication.
Synopsis
#include <GL/ice-t.h>
void icetDataReplicationGroupColor( GLint color );
Description
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.
Errors
None.
Warnings
None.
Bugs
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
rendered.

This man page should never be installed. It should just be used to help
make other man pages.
