Field:
The image on a TV-screen is drawn in two parts:
odd and even lines, which, once together, are known as frames.
Fill
rate:
This is the number of pixels
that the graphics board can render (this means texturing
and shading) over a given period of time. The raw
fill rate of a board is calculated by multiplying the number of pixels it processes
per clock by its core clock.
Flat panel:
Flat panels mark the latest development in display technology. Standard CRT
displays rely on cathode ray tubes, which account for the depth of most computer
monitors and TV sets. Flat-panel technology eliminates these tubes and substantially
improves picture quality.
Fogging:
This is a derived effect of alpha
blending which adds realism by combining a transparency effect and a continuous
blend of 3D objects in background colors. It adds the effect of density to the
atmosphere.
Fps
(Frames per second):
This
is the number of frames that are drawn on-screen per second. The greater the
number of frames, the greater the motion realism. A standard TV image is refreshed
25 (PAL) or 30 (NTSC) times per second. The 3D Prophet graphics boards can display
images on your PC at the correct speed and can accelerate motion up to 60 or
100 frames per second if the game is programmed for this.
Frame:
This is the complete image that appears on a TV-screen,
being made up of two scan fields.
Frame
buffer:
This is the part of the memory that is used
to store a complete image. The frame buffer usually contains 2 frames: one that
is being calculated while the other is being sent to the monitor (see multi-buffering).
Full Scene
Anti-Aliasing (FSAA):
A technique to eliminate
jagged edges (see jaggies and aliasing)
from the whole of a 3D scene's appearance, as opposed to the Edge
Anti-Aliasing technique, which exclusively processes the edges of objects.
FSAA therefore improves the quality of images, and enhances visual comfort.
