Hi Daniel,
I tried to reproduce this but I couldn't works fine for me. Are you
using exactly the same OpenSG libs on your client and server machines?

Hello,
I just experienced a very strange behaviour regarding client/server
rendering with multicast and vrml loading.
I want to use multicast, because i am rendering on 4 machines
(multidisplay Environment 180 degrees with stereo in the middle) and
hope that my fps will rise a little...
After debuging my code i came down to this very strange behaviour even
with the Tutorials:
I did run on ana1:
12ClusterServer -w -m ana1
On another machine:
13ClusterClient -f trollHead.wrl ana1
working, model shows up after 2 secs.
13ClusterClient -m ana1
working, the torus shows up
13ClusterClient -m -f trollHead.wrl ana1
not working, the windows pop up, but the model does not get displayed,
even after 2 minutes
So it seems, that multicast doesnt work if i load a vrml from disk????
Its the same with any file...
How can there be a relation?????
Anybody any ideas?
I am running Suse Linux 9.2 and an about 8 weeks old OpenSG-cvs Version.
And I get no conn to cvs.sourceforge.net at the moment....
A puzzled Daniel

Hi Dirk and all opensg users,
I have a small question about performance of rendering and possible
ways of optimizing my code.
In my scene there are several hundred textured boxes, the most of them
using the same SimpleTextureMaterial. I added to all the materials in the
scene an SHLChunk, holding a small shader featuring shadow mapping.
In the moment I turn on shadows, performances of the application
drop significantly (from kinda 40 fps to a mere 5-6). If the boxes are
hidden by a flat panel, the application does not improve it’s speed,
so I guess that OpenSG isn’t doing any occlusion culling. Is there a way
to turn on occlusions and avoid the shading of invisible pixels?
Using a simpletexturedmaterial instead of a MateriaChunk, can end up in
some weird OpenGL state swapping and in a resulting lost of
performance???
Is there a way to check what part of my application is working as a
bottleneck?
Thanks for the help,
Enrico
