Frequently Asked Questions (FAQ)
Q1 What is AGP and what does it mean?
Answer
The Accelerated Graphics Port (AGP or A.G.P) is a high
performance, component level interconnect targeted at 3D graphical
display applications and is based on a set of performance
extensions or enhancements to Peripheral Component Interconnect
(PCI). A typical 3D application requires tremendous amount of
memory to render 3D scenes. AGP provides a cost-effective way of
shifting some of 3D rendering data structures into system memory
from frame buffer of 3D graphics accelerator. The 3DImàge985
supports the higher performance 2X or execute mode of AGP which
allows data structures to be executed in system memory space
without being copied into the frame buffer of 3D graphics
accelerator prior to use by the accelerator.
Q2 Why do we need 3D graphics capability in our PC?
Answer
3D technology is becoming increasingly important (and common)
not only in games, but also in other applications such as VRML,
which allows 3D scene descriptions in Web applications. 3D
technology is used for image editing, modeling, and an increasing
number of in home and business applications. In games, as well as
other applications, 3D acceleration not only allows better visual
qualities and more realistic scenery attributes than software alone,
but it also allows a higher frame rate, which translates into a more
interactive experience for the end users.
Q3 What does “ Rendering Engine” mean?
Answer
“ Rendering Engine” generically applies to the part of the graphics
engine that draws 3D primitives, usually triangles. In most
implementations, the rendering engine is responsible for
interpolation of edges and "filling in" the triangle.
Q4 What does the set-up engine do in a graphics controller?
Answer
A set-up engine allows drivers to pass triangles in the form of raw
