Render Nodes Hardware Setup
Network
All the rendering nodes as well as the XR
Engine must be connected in a fast local
network, preferably dedicated to them and
the StarTracker.
All the devices should have a static IP
address for easy maintenance. Prepare a list
of the addresses, as it will be necessary for
software setup. Install Tight VNC for remote
access and set the project up in Perforce.
Drivers
Install the latest drivers. Daisy Chain the
system by having an external sync source
come into the master Sync Card via a BNC
cable (Genlock) and spread the signal
further down the chain using RJ45 cables.
Ideally each render node should have only
one display connected to it (the LED
processor) If more than one are necessary
configure them via Nvidia Mosaic.
Synchronisation
Synchronisation of the LED screen output is
a key to a seamless shoot. It is crucial that
all the sections of the volume are rendering
at the same time, so there is no tearing
between sections.
This is achieved by using an Nvidia Quadro
Sync Card II. Every Render node has one of
them connected to the GPU to guarantee
synchronous rendering.
Refer to Frame Lock Configuration in the
User
for more information:
Quick setup
1. Connect on-set genlock to the House
Sync to the
Primary Render Node
2. Daisy chain the rest of the rendering
nodes with CAT-5 Ethernet cables.
3. Enable VSync in NVIDIA control panel
4. Configure
the
synchronisation
in
Synchronise Displays. Define whether it
is a timing server (only the
Primary
Render Node
)
