History of Graphics In 1983 Intel made the iSBX 275 Video Graphics Controller Multimodule Board for industrial systems based on the Multibus standard.
Released in 1985, the Commodore Amiga was one of the first personal computers to come standard with a GPU.
Nvidia was first to produce a chip capable of programmable shading, the GeForce 3(code named NV20).

Further,many more graphics cards were introduced like The Nvidia GeForce256(also known as NV10) the ATI Radeon 9700 (also known as R300), etc which have brought about a revolutionary change in graphics today!

What is a Graphic Card?-> “Visual center” of a computer's brain-> Outputs Images to the computer's display -> Incredibly powerful-> Perform a variety of useful functions, especially in the world of computer gaming.

Types Of Graphics Cards
Integrated Graphic cards:- • Built in to the motherboard• Serve Basic display functions• Also called On-Board Graphic cards
PCI Graphic cards:- • Use PCI Slot on motherboard• Older motherboards have PCI Slots• A little Out-of-date

Types Of Graphics CardsAGP Graphic cards:- • Connected with AGP port on motherboard• Have four speeds 1x,2x,4x and 8x• Faster than PCI cards
PCI-E Graphic cards:- • Use PCI-E Slot on motherboard
• Most advance and powerful cards• PCI-E graphics cards can be accelerated to 16 times

How graphic Cards works?
GPU calculates the position and
color of each onscreen pixel
Save visual data Sends it to the RAMDAC (digital
to analog converter) to output to
the monitor.

Advantages of Graphics Card :Motion Blur :
This technique is used to blur objects in fast motion.
![Page 30: GRAPHIC CARD](https://reader035.vdocument.in/reader035/viewer/2022062503/58cfeb641a28ab11578b55e1/html5/thumbnails/30.jpg)
3. Texture Mapping :
This technique allows addition of details on surfaces without adding complexity.
4. Lens flare :This technique allows producing lightning effect as similar as light emitting from light sources.
5. Fresnel Effect :
This technique allows us applying shadows and reflections over an object through different angles.

6. Anisotropic Filtering :
This technique enhances quality of textures at oblique viewing angles.
Poor texture quality
Detailed textures

7. PICTURES COMES TRUE :
High Definition effects can be added to images so that they looks like real photos.
