HP c8000 Release Note page 3

Hewlett-Packard supports the following 3D graphics application programming
interface (API) libraries for use with the HP-UX 11.11 (June, 2004) release:
HP OpenGL, HP PEXlib, HP-PHIGS, and Starbase. Note that the HP PEXlib, HP-
PHIGS, and Starbase APIs are not supported on the ATI FireGL X1 and ATI FireGL
T2. For information about enhancements and changes to the current version of
each API, consult the separate Release Notes document(s) as described in the
ANNOUNCEMENTS section of this document (the Release Notes file(s) for a
particular API will not be present if the associated optional product has not
been installed on your system).
ATI FireGL X1 and ATI FireGL T2 Information
===========================================
The ATI FireGL X1 graphics device is HP's high end 3D graphics product. The
ATI FireGL T2 graphics device is HP's mid-range 3D graphics product. These
devices are supported on the following HP workstations:
* C8000
For more information on these devices (including supported visuals and other
device attributes), refer to the following documentation which can be found by
visiting HP's website at http://www.hp.com/support/workstation_manuals:
* "Graphics Administration Guide"
* "OpenGL Implementation Guide"
Discontinuance Information
==========================
Hewlett-Packard evaluates the capabilities and device support of HP-UX on an
ongoing basis. There are no graphics devices being discontinued with this
release.
Threads Information
===================
HP's 3D graphics APIs (HP OpenGL, HP PEX, HP-PHIGS, and Starbase) all support
Level 1b threads for this release. This means HP's 3D graphics APIs can be
used in a threaded application, but all 3D graphics calls must reside in a
single thread. Other threads can be used for computations, etc.
Note that using OpenGL graphics in a Kernel threaded application requires that
the application link with libpthread.sl (not the archived version,
libpthread.a). Also note that OpenGL libraries are not cancel safe or fork
safe.
For more information on using threads, see the following documentation:
* The devresource.hp.com web site (see "Threads and Multiprocessing")
* The "OpenGL Programming Guide"
* The "OpenGL Reference Manual"
* "Threadtime" by S. Norton and M. Dipasquale
Additions to X11 Support
========================
HP's Xfree86-based Xserver supports the ATI FireGL X1 and ATI FireGL T2
graphics devices. For more details on the features and capabilities of this
Xserver, please refer to the "Graphics Administration Guide" document.
