Hello there,

We've been asked to supply the technological solutions to create a 360° video panorma for a semi-permanent interactive audiovisual installation in a museum. We will use 5x 720p projectors to make the panorama projection.

User interaction data (preferably through OSC, but DMX should be no problem) will be provided by a computer running custom software that analyzes a realtime feed from a thermographical camera in various ways.

At the moment it is unclear how the interaction will be used in the 'interactive storytelling'. It is however clear that a story should be told, using surround sound and panoramic video, with a certain degree of audience participation.

1. Essential in the suggestion of the 'seamless' panorama is to have it as frame sync as possible.
2. It is very likely there will be mixing of layers, crossfading A/B channels at a minimum. The same thing as 1. is important here, when crossfading A/B it should be as seamless as possible, preferably invisible, to keep the suggestion of a seamless panorama alive.
3. Sync start/stop/jump

etc.etc.

So on the one hand there's the necessity for a very steady sync of the various actions on the different outputs. On the other hand there's the 720p material, stereo sound on each output.

I have the feeling that the more computers one uses, the harder it becomes to keep it all sync. On the other hand, for the sake of smooth playback etc. I'd say that three machines with the following specifications should be able to do the trick :

2x 3.0GHz Quad-Core Intel Xeon
4GB (4x1GB)
NVIDIA Quadro FX 5600 1.5GB
750GB 7200-rpm Serial ATA 3Gb/s
3x Mtron MSP-SATA7535-128 (128GB)

Or would one of these with two th2g be enough ?

thanks !
