In response to Scott's question, we have developed a more advanced
DXF loader for Performer which we use in our virtual reality
consulting. We have used it to perform flythroughs of architectural
data coming from the ARRIS CAD system. It is not yet available as a
separate product, but that could change if there is sufficient
interest.

We have also developed a C++ class library for VR devices that is
now in beta test. Currently it supports 10 devices, including
sensors from Ascension, Polhemus, Logitech, Spaceball, and Origin,
plus gloves from VPL and Virtex. All are handled in a device-
independent way, including conversion of data into Performer's
coordinate system, via the base sensor class. Filtering operations
such as origin offsets, tolerance levels, and scaling are also
included. Device-dependent features can be accessed via the derived
class for each supported device. We found this library made it easy
to add VR device control to Performer code.

We are looking for additional beta customers to help ensure that
this device software is usable with a variety of Performer
applications. Versions are available for both IRIX 4.0.5 and 5.2,
running with SGI C++ 3.0. If you are interested, please contact me
via e-mail.

Thanks,
