Thank you all,
We are trying to build a cave environment based on OSG and MPI for
cluster synch,
(we have tryed vuggler... but on windows it failed .. a lot..), so we
have successfully implemented a proof of concept using the sceneviewer
of the old osg and MPI.
Now we are adding stereo, and I think it is done! (with a lot of work,
and after reading a lot of osg code), the new osgViewer is ver good
for multi GPU, we have 2 nvidia 8800GTX to control 2 projectors and
the osg horizontal split stereo worked pretty good, so we only needed
to add the cluster swap lock, so... I copied the osgViewer so I cold
add a glFinish operation to the GraphicsThread, and added the MPI
barrier after it to synch the cluster. we will need to test it a lot,
but I think it works.
I asked about the perspective because we need to set a different
perspective for each node of the cluster. mean while i' understood I
have to set perspective to the left and right cameras after realize.
(right?)
for the view matriz I have a dummy manipulator that I update using
setByMatrix using the matrix send by the master node.
thanks
