For example, if the Professional Workstation XP1000 with PowerStorm 300 graphics or Compaq Professional Workstation SP700

Scientific visualization has been one of the driving forces in high-end Professional Workstations where shaded image performance is critical, the geometry accelerated PowerStorm 600 is the best choice.

On the other hand, lights can be directional, have "barn doors" (controls that allow screening the light, much like the flaps on professional theater lights), fall off with distance, have color, cast shadows, and other even more complex functions. These lighting models are extremely complex, very

The AGP bus is up to 8 times as fast as the PCI PCI bus is adequate for today's 3D graphics workloads. This is supported by graphics benchmark results when are almost identical when AGP and PCI versions

Graphics: The Workstation
Difference
Abstract:
Graphics are the most visible and most critical part of
workstations.
Focusing on 3D graphics, this paper explores the role
and importance of graphics and recommends graphics products for
specific needs.
A discussion of graphics implementation issues is included, which
examines when graphics operations make sense to implement in
hardware and which should remain in software.
Finally, key
graphics interfaces -- both software and hardware -- are explored.
This paper should increase understanding of workstation graphics
and help in choosing graphics devices.
