9. ADDENDA -- ADDITIONAL GRAPHICS INFORMATION
ATI FireGL X1 and ATI FireGL Z1 Information
===========================================
The ATI FireGL X1 graphics device is HP’s new high-end 3D graphics product.
The ATI FireGL Z1 graphics device is HP’s new mid-range 3D graphics product.
These devices are supported on the following HP workstations:
* zx2000
* zx6000
The ATI FireGL X1 and ATI FireGL Z1 require the HP-UX 11.23 Operating
Environment for IPF-based systems (June 2003 release or later).
The attributes of the ATI FireGL X1 and ATI FireGL Z1 devices include:
* 8 Overlay planes
* 48 Image planes (for 24-plane single buffered or 24/24
double-buffered rendering)
* A total of 5 hardware color maps (1 image, 4 overlay)
* Support of the Depth 8 PseudoColor Overlay visual
* Support of the Depth 24 TrueColor Image visual
For additional information on these devices, refer to the OpenGL
Implementation Guide and the Graphics Administration Guide.
Threads Information
===================
HP OpenGL supports Level 2 threads for this release. This means HP OpenGL can
be used in a threaded application. More than one thread can use OpenGL. A
given context can only be current in one thread at a given time.
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 additional information on using threads, refer to the following
documentation:
* The http://www.docs.hp.com/ Web site (search for "Threads and
Multiprocessing")
* The OpenGL Programming Guide
* The OpenGL Reference Manual
* Threadtime by S. Norton and M. Dipasquale
64-bit Computing Information
============================
64-bit applications are supported with OpenGL for this release. Applications
using 64-bit computing are supported on SPUs with 64-bit capabilities only;
they are not supported on 32-bit SPUs.
For information on porting your application to take advantage of 64-bit
capabilities, see the http://www.docs.hp.com/ Web site. Search for "64-bit
Computing" and "Porting."
Note that 64-bit OpenGL allows "large data space" because the pointers are now
64-bit. But, the OpenGL data types themselves are the same as the 32-bit
library. For example, GLint is a 32-bit integer, not a 64-bit long.
All 64-bit OpenGL libraries are located in:
/opt/graphics/OpenGL/lib/hpux64.
The following sample compile and link lines may help you to build your
application once it has been ported to take advantage of 64-bit capabilities.
* Sample 32-bit compile and link:
cc -Ae -z -I/opt/graphics/OpenGL/include -I/usr/include/X -o cube.32 \
cube.c -L/opt/graphics/OpenGL/lib/hpux32 -L/usr/lib/hpux32/X11R6 \
-lGLU -lGL -lXhp11 -lXext -lX11 -lm -ldld
* Sample 64-bit compile and link:
cc -Ae +DD64 -z -I/opt/graphics/OpenGL/include \
-I/usr/include/X11R6 -Wl,+compat -o cube.64 cube.c \
-L/opt/graphics/OpenGL/lib/hpux64 \
-L/usr/lib/hpux64/X11R6 -L/usr/lib/hpux64 \
-lGLU -lGL -lXhp11 -lXext -lX11 -lm
