Hi...
Assume that I have 4 graphics workstations that are connected to 4 displays.
Is it possible to describe a configuration that does the following?
1. Each node render 1/4 of the database on a pbuffer that is the size of 4 displays
Yes.
2. Each node composite the images from the three other nodes and display
Not right now. The images will be placed wrt their relative position on the source channel. You could do a prototype by resetting the frame offset to 0 in Channel::frameAssemble.
Alternatively have a look at the view equalizer.
BTW, if there are more render nodes than the display nodes (those that are connected to a display in a tiled display), what is the normal arrangement of the resources?
Use a view equalizer and send feedback. It is fairly new.
Hth,
