such as Gouraud shading, antialiasing, depth buffering, fog and atmospheric
effects, and blending. This should enable your 3D applications to run more
quickly and with good interactive performance. Additional benefits to using
the POWER GXT3000P graphics accelerator are:
• Increased subpixel addressing over previously supported adapters
• Face culling support
• OpenGL polygon offset support
• OpenGL polygon mode support
• OpenGL specular lighting support in hardware
• Trilinear texture mapping
Featured hardware enhancements over the POWER GXT800P Graphics
Adapter include:
• OpenGL and graPHIGS lighting mode
• 3D texture mapping
• Video scaling
• Stereo in a window
The POWER GXT3000P offers a highly flexible frame buffer that can be
dynamically configured to provide a broad set of color and feature options.
When using OpenGL and graPHIGS APIs, the GXT3000P offers support for
8-bit and 24-bit double-buffered color, and also includes 8-bits of
double-buffered alpha buffers for more realistic transparency control. In
addition, this accelerator provides 8-bit overlay buffers that enhance the
speed of a graphical user interface (GUI), 8-bit stencil buffers, 8-bit window
ID buffer, and a 24-bit Z-buffer for hidden surface removal operations. The
POWER GXT3000P allows for the display of up to 16.7 million simultaneous
colors.
The GXT3000P graphics accelerator is a single 64-bit PCI card that attaches
to one 64-bit PCI slot in the RS/6000 Models 150 or 260, but covers the slot
adjacent to it (uses two slots of space).
Stereo viewing requires additional equipment, such as emitter, cable and
glasses, in addition special software support.
