> QUESTIONS
>
> 1. Each ImmersaDesk will have at least 100 Mb/s individually switched IP
>    connectivity to NCSA's core network, and from there to the vBNS and 
the
>    outside world. Multicast will also be provided to other vBNS sites.
>
>    Is this sufficient for your application's networking needs?
>    If not, please explain.

	Yes, it's sufficient.

>
>    Will one network connection be sufficient?
>    If not, how many will be needed?

	Yes, one network connection will be sufficient.

>
>    If your application will do point-to-point communication, what other
>    sites will you need connectivity to?

	None. The application does not need point-to-point communication.

>
>    If your application requires multicast, what other sites will you
>    need connectivity to?

	The IP multicasting connectivity is required to:

	Virtual Environment Technology Laboratory (VELT), University of Houston
	VR lab, University of Utah
	Center for Parallel Computers (PDC), Royal Institute of Technology, Sweden

>
> 2. If your application is an ImmersaDesk application, what will the
>    frame rate be on the following hardware:
>
>    Octane
>      Irix 6.4, dual R10K cpus, MXi graphics, 256 MB RAM

	Don't know, newer tried.

>
>    Onyx
>      Irix 6.2, four R4400 CPUs, 256 MB RAM,
>      RE2 graphics (with two RM5s of texture memory)

	12-16 fps.

>
>    Onyx
>      Irix 6.2, four R10K cpus, 256 MB RAM,
>      IR graphics (DG4-2 with two RM64s of texture memory)

	Don't know, newer tried.

>
>    Onyx2
>      Irix 6.4, two R10K cpus, 256 MB RAM,
>      IR graphics (DG4-2 with two RM64s of texture memory)

	Don't know, newer tried.

>
> 3. Beyond a standard SGI (as listed above) running an ImmersaDesk, does 
your
>    application require any other type of machine/OS. such as a SUN, PC,
>    or Macintosh?

	Yes.

>
>    If so, what machine/OS is needed? Can you supply it if needed?

	An Indy/O2 SGI with video/audio board. IRIX 5.3-6.2 - doesn't 
matter.(vangogh)
	An HP. (vps.ncsa.uiuc.edu is exactly what we need, it has all the software 
installed on it)

>
> 4. An ImmersaDesk will be available as a large-format, passive display
>    device capable of displaying output from both SGIs and PCs.
>
>    If applicable, does your application require any other type of display
>    device? If so, please describe.

	No.

>
> 5. Does your application require more than 500 MB of local disk space?
>    If so, how much local disk space does it need?

	No.

>
> 6. Does your application require a telephone on the demo show floor?
>    Will it require more than one telephone line? If so, how many?

	A phone is certainly a useful thing.

>
> 7. Each ImmersaDesk machine will have the following software installed:
>
>    C/C++   (7.1 or 7.2)
>    F77/90  (7.1 or 7.2)
>
>    CAVE, pfCAVE Libs  (2.6)
>    CAVERN
>    MPI
>    NEXUS/GLOBUS
>    NCSA vss and sound lib
>
>    CaseVision
>    CosmoPlayer  (1.0.2)
>    CosmoWorlds
>    Java Development environment (SGI's JDK)
>    Inventor
>    Performer  (2.1 or 2.2)
>
>    GNU tools (gmake, gzip, emacs/xemacs)
>    Habanero
>    Multicast tools (sdr, vic, vat)
>    Netscape Communicator
>
>    Does your application require any additional software? If so, please 
list.
>    Can you provide it along with suitable licenses, if needed?

	Yes, we will need Sense8's WTK library and license codes for the IDesk 
machine. There are some difficulties involved in obtaining license codes. 
We are currently working on resolving it.

>
> 8. Beyond a standard SGI (as listed above) running an ImmersaDesk,
>    does your application require any auxiliary computing resources *not*
>    on the show floor (eg. remote servers or supercomputers)?

	No.

>
>    If so, what resources do you need?
>    Have you made the necessary arrangements for them?
>
> 9. Beyond a standard ImmersaDesk configuration, does your application
>    require any additional input/output devices?

	Yes.
>
>    If so, what are they? Can you provide them?
>    What is needed to connect them to an ImmersaDesk?

	We will need an ADD board. We will take it from one of NCSA's workstations 
(picasso).
>
> 10. Does your application use the NCSA 'vss' sound server?
>
	Yes.

>     Does your application require the use of a dedicated Indy as a
>     sound server?

	No. The soundserver should be run on the IDesk's workstation.
>
>     Does your application do ImmersaDesk-to-ImmersaDesk communication
>     and require a corresponding audio connection?

	Yes.
>
>     If your application is a non-VR presentation, does it need 
amplification?

	Our app needs amplification.
>
>     What other audio requirements do you have?

	That Indy SGI mentioned in section 3, among other things will be used for 
to run audio/video communication software.

>
> 11. Does your application use the standard ImmersaDesk VR tracker daemon?
>     If not, which tracker daemon does it use?

	Yes, it uses the standard trackers.
