hidden surface removal, depth-cueing, and transparency. This enables your
3D applications to run more quickly and with good interactive performance.
For OpenGL, texture maps up to 1024x1024, and a 64-bit accumulation
buffer are also supported through software.
The GXT550P offers highly flexible frame buffers that can be dynamically
configured to provide a broad set of color and feature options. When using
OpenGL, PHIGS and GL 3.2, the GXT550P supports 8-bit, 12-bit, and 24-bit
double-buffered color and also includes 8-bits of double-buffered alpha
buffers for more realistic transparency control.
The GXT550P provides 8-bit overlay buffers, which enhance the speed of a
graphical user interface (GUI), 8-bit stencil buffers, and 24-bit Z-buffer for
hidden surface removal operations. This accelerator provides for the display
of up to 16.7 million simultaneous colors from a palette of 16.7 million colors
and four hardware color maps.
The GXT550P graphics accelerator is a 32-bit PCI cards that plugs into a
single PCI slot. It supports display resolutions of 1280x1024 and 1024x768
and refresh rates from 60 Hz to 85 Hz, including refresh rates that comply
with the ISO 9241 Part 3 ergonomic standard. When used with other
compliant components, including monitors, this standard provides improved
viewing, reduced flicker, reduced reflection and sharper characters. These
features, coupled with IBM’s powerful RS/6000 43P Models, make the
POWER GXT550P an ideal solution for demanding 3D application needs.
5.2.4 POWER GXT3000P Graphics Accelerator (# 2825)The POWER GXT3000P Graphics Accelerator for 3D visualization marks a
breakthrough in performance and functionality for design and visualization
solutions. It is the highest performing IBM graphics accelerator available for
RS/6000 workstations. The graphics subsystem, combined with IBM’s
POWER3 and PowerPC-based workstations, delivers outstanding speed and
3D performance for demanding applications in mechanical design and
engineering, for aerospace and automotive, petroleum exploration and
production, scientific visualization and other technical industries.
The GXT3000P is well suited for users with applications that require
high-performance 3D graphics. It delivers significant improvement in
functionality and performance (up to three times the performance of its
predecessor, the POWER GXT800P graphics adapter) at a lower cost.
The GXT3000P provides hardware acceleration for the new OpenGL 1.2
version of the API. This adapter accelerates advanced 3D graphics functions
