Subject: -1- What is IRIS Performer?
Date: 12 Dec 95 00:00:01 EST
IRIS Performer provides a powerful and extensible programming
interface (with ANSI C and C++ bindings) for creating real-time
visual simulation and other interactive graphics applications.
IRIS Performer 2.0 supports both the IRIS Graphics Library (IRIS
GL) and the industry standard OpenGL graphics library; these
libraries combine with the IRIX operating system and REACT
extensions to form the foundation of a powerful suite of tools and
features for creating real-time visual simulation applications on
Silicon Graphics systems.
IRIS Performer is an integral part of the Onyx/Onyx2 RealityEngine
& InfiniteReality and Indigo2/Octane Impact graphics systems and
provides interfaces to advanced features of RealityEngine-class
graphics. IRIS Performer is compatible with uniprocessor and
multiprocessor SGI graphics platforms and attains maximum
performance on all. IRIS Performer provides an extensible basis
for creating real-time 3D graphics applications in the fields of
visual simulation, entertainment, virtual reality, broadcast video,
and computer aided design. IRIS Performer is the flexible,
intuitive, toolkit-based solution for developers who want to
optimize performance on Silicon Graphics systems.
IRIS Performer consists of two main libraries, libpf and libpr, and
four associated libraries, libpfdu, libpfdb, libpfui, and
libpfutil.
The basis of IRIS Performer is the performance rendering library
libpr, a low level library providing high speed rendering functions
based on pfGeoSets, efficient graphics state control using
pfGeoStates, and other application- neutral functions.
Layered above libpr is libpf, a real-time visual simulation
environment providing a high-performance multi-processing database
rendering system that takes best advantage of IRIS symmetric
multiprocessing CPU hardware.
The database utility library libpfdu provides powerful functions
for defining both geometric and appearance attributes of three
dimensional objects, encourages sharing of state and materials and
generates efficient triangle strips from independent polygonal
input.
The database library libpfdb uses the facilities of libpfdu, libpf,
and libpr to import database files in many popular industry
standard database formats. These loaders also serve as a guide to
developers creating new database importers.
libpfui contains user interface building blocks for creating
manipulators common to many interactive applications. This library
has both a C and C++ API and is GL independent.
Completing the suite of libraries is libpfutil, the IRIS Performer
utility library. It provides a collection of important convenience
routines implementing such diverse tasks as smoke effects,
MultiChannel Option support, graphical user interface tools, X and
IRIS GL event collection and management, and traversal functions.
For aid in application development, IRIS Performer includes sample
application source code ranging from simple programs to illustrate
particular features to the comprehensive, GUI-driven file viewer
perfly.
In addition to these SGI-developed tools, IRIS Performer also
includes a very large repository of sample code, databases, games,
and movies contributed by the Friends of Performer: companies and
individuals with services of general interest to the IRIS Performer
community. We encourage you to sample their wares.

Subject: -4- The IRIS Performer mailing list
Date: 12 Dec 95 00:00:01 EST
The IRIS Performer mailing list is a resource for developers who
are using IRIS Performer to maximize the performance of their
graphics applications on Silicon Graphics hardware. The list is an
unmoderated, free-form discussion of IRIS Performer with issues
both technical and non-technical; and provides feedback to Silicon
Graphics about the product. Much like the comp.sys.sgi.*
newsgroups, it is not an official support channel but is monitored
by the IRIS Performer development team, so it's an excellent source
of early information about upcoming events and product features, as
well as a venue for asking questions and having them answered.
To become a subscriber to the IRIS Performer mailing list you must
send email to:
info-performer-request@sgi.com
New subscribers are added "by hand". Once your request is processed
you will recieve submission/posting instructions, some guidelines,
and a current copy of the Performer Frequently-Asked-Questions (FAQ)
list.
The mailing list has become rather large and carries several
hundred messages per month. A performer newsgroup with a gateway

Subject: -8- How does IRIS Performer relate to IRIS Inventor?
Date: 26 Jun 93 00:00:01 EST
The short answer is, Performer was designed for vis-sim, while
Inventor was designed to be more general purpose.
IRIS Performer is for developers who need to extract maximum
performance from SGI machines for visual simulation, virtual
reality, game development, and high-end CAD systems. Often these
applications need multi-processor Onyx systems with multiple
RealityEngine pipelines with a high degree of parallelism and
running at fixed frame rates.
Inventor is designed for maximum programmer productivity when
writing other kinds of 3D applications, like modelling, animation,
visualization, etc.
Both toolkits are general purpose enough that they could be extended
into the domain of the other, but the question you should consider is
"what is the *fundamental* goal of my graphics development?" If it's
portability to non-SGI systems, easy X-window system integration, or
handy graphic widgets, IRIS Inventor is for you. If it's brochure-
level performance in advanced graphic applications for the specific
domains listed above, then IRIS Performer would be the likely tool.

Historical/Background information:
Note that the above list is included only for completeness' sake.
You probably do not need the "highest numbered" version of
Performer. For example, Performer 2.1 was released -before-
Performer 2.0.4.
Except for Onyx InfiniteReality, systems running 6.2 should load
performer_eoe 2.0.1 from the IRIX cd, and performer_dev 2.0 from
the Performer 2.0 CD. Then load the patches as described below.
Onyx InfiniteReality systems running 6.2 should load performer_eoe
and performer_dev 2.1 from the Performer 2.1 cd.
Systems running 6.3 (O2) should load performer_eoe 2.0.3 from the
IRIX cd, and performer_dev 2.0 from the Performer 2.0 CD. Then
load the patches as described below.
Systems running 6.4 (Origin 200, Origin 2000, Onyx2 IR, Onyx2
Reality, Octane) should load performer_eoe 2.0.4 from the IRIX cd,
and performer_dev 2.0 from the Performer 2.0 CD. Then load the
patches as described below.
Performer 2.1 is only officially supported on Onyx InfiniteReality
systems running IRIX 6.2. It may work on other platforms, but is
only fully tested on Onyx IR. Also note that 2.0.4, 2.0.3, or
2.0.1+patch1347 are all more recent than 2.1.
The N32 and N64 libraries in Performer 2.0 are not intended for
systems running IRIX 6.1. If you require N32 or N64 functionality,
you need to upgrade to 6.2 (or above) and use 2.0.1 (or above).
Performer 2.0 was originally shipped for 5.3. In 6.2, the
performer_eoe portion was updated to version 2.0.1; in 6.3, to
2.0.3; and in 6.4, to 2.0.4. performer_dev 2.0 (plus patch) is to
be used with each.
No further releases of Performer are planned for IRIX 4.x or 5.x.
Performer 1.2 was shipped for both 4.0.5 and 5.2 systems. If you
are using IRIS Performer 1.2, only install that version that is
appropriate for your machine. The IRIS Performer version is
indicated by the "IRIX4" or "IRIX5" string in each product name.
IRIX4 products should only be installed on 4.0.5 systems. IRIX5
products can be installed on 5.2, 5.3, 6.0.1, and 6.1 systems.
When a choice is possible between using Performer 1.2 with IRIX 5.x
or IRIX 4.0.5, IRIX 5.x is highly preferable. IRIX 5.3 is the
current operating system release and contains many bug fixes and
enhancements utilized by IRIS Performer. IRIS Performer 1.2/IRIX4
was intended only for users who are unable to upgrade to IRIX 5.x.
------------------------------

Subject: -15- Is there an IRIS Inventor file reader for IRIS
Performer?
Date: 12 Dec 95 00:00:01 EST
Yes. IRIS Performer 2.x ships with a fully-functional Open
Inventor 2.0 file loader.
IRIS Performer 1.2 ships with a minimal .iv reader that will read a
subset of the IRIS Inventor 1.0 format.
A port of the more robust 2.x reader for Open Inventor files is
also available for Performer 1.2, in the Performer FTP Archives:
ftp://sgigate.sgi.com/pub/Performer/src/pfiv1.6.tar.Z
No Inventor file reader exists for Performer 1.0 or 1.1.
------------------------------
Subject: -16- What are the .tlf files used by the Performer Town and
Village?
Date: 8 Apr 94 00:00:01 EST
They are encrypted .flt files of the Town and Village database.
Only the "demo" version of perfly shipped with RealityEngine
systems in demos.sw.visualization can read these files.
Unencrypted versions of the Town and Village databases are included
in the performer_friends.sw.town subsystem of Performer 1.2 and 2.0.

Subject: -17- What are the minimum requirements for using IRIS
Performer?
Date: 12 Dec 95 00:00:01 EST
IRIS Performer 2.1 is only for IRIX 6.2
IRIS Performer 2.0.4 (eoe) is only for IRIX 6.4
IRIS Performer 2.0.3 (eoe) is only for IRIX 6.3
IRIS Performer 2.0.1 (eoe) is only for IRIX 6.2.
IRIS Performer 2.0 is for IRIX 5.3, 6.1, or 6.2.
Patch 1347 (eoe) is only for IRIX 6.2
Patch 1396 (eoe) is for IRIX 6.2 or IRIX 6.3
Patch 1392 (dev) is for IRIX 6.2, IRIX 6.3, or IRIX 6.4
IRIS Performer 1.2/IRIX5 requires IRIX 5.2 or 5.3.
IRIS Performer 1.2/IRIX4 requires IRIX 4.0.5. Because IRIX 4.0.5F
added several new Graphics Library (GL) calls to support
RealityEngine features, any application that uses GL routines or
tokens found only in 4.0.5F and later, will not run properly under
4.0.5C and earlier releases.

Subject: -18- Binary Compatibility on different machines
Date: 12 Dec 95 00:00:01 EST
Applications compiled with IRIS Performer 2.0 using IRIX 5.3 will
run unmodified across all SGI platforms. For best performance, use
IRIS GL with RealityEngine and other pre-Impact systems and use
OpenGL for Impact and post-Impact graphics hardware.
OpenGL-oriented systems provide the IGLOO (Iris GL on OpenGL)
portability layer to execute IRIS GL applications, but it is not
the maximum performance route. Performance oriented developers are
advised to generate both IRIS GL and OpenGL executables, by linking
with the API-compatible IRIS Performer 2.0 IRIS GL and OpenGL
libraries. In this way, you can assure optimum performance across
present and future graphics systems. For OpenGL development on
RealityEngine with IRIX 5.3, patch 154 (or a superseding patch)
