2.  Intro
to Video/ Graphics cards
 Components
 Functions of a Graphics Card
 Various types
 Color Depth
 Bit Depth
 Uses
 Advantages

3.  Also
known as Video display Adapters.
 Is a board that plugs into the computer to
give it display capabilities.
 The display capabilities of a
computer, depends on:


the logical circuitry (provided in the video
adapter) and
the display monitor.

8. Intel: develop IGPs (integrated graphics
processors)
 AMD (acquired ATI) develop GPUs
 Nvidia also develop GPUs
 Different manufacturers take GPUs and other
components to assemble video cards; thus
creating slight variations of video cards with
same GPUs
 Video cards are marketed with GPU
manufacturer’s brand name
 Most popular video brands are the Radeon of ATI
and GeForce of Nvidia


9.  Determined
by the intensity of three
beams of light (Red, Green and Blue) and
the amount of information stored about a
pixel
 Different
Modes
8 Bit – 256 Color Mode
16 Bit – High Color mode
24 Bit – True Color Mode

10. Bit Depth : The number of bits used to describe a
pixel is known as its bit depth.
 Example:


24bit – Bit Depth means

8 bits for each Primary color,

around 17 Million Color Combinations,

around 10,000,000 discernible Colors

Thus offers True Color System

12.  Animation
 Gaming
– both PC and console
 Design/Drafting
 Special effects creation/editing
 Medical Instruments
 And other purposes where fast rendering and
high resolutions are needed

13.  Motion
Blur
 Texture
Mapping
 Lens Flare
 Fresnel Effect
 Anisotropic Filtering

14. Texture Mapping
Lens Flare
Motion Blur
Fresnel
Efect
