Animated text, animated wallpper,glowing effects,etc are nothing but graphics. Slide 4: History of Graphics & Graphics Card : Graphics were used with computer hardware before the first graphic card was invented. The first computer graphic to be used on a computer was in the 1940s, when the Whirlwind I was developed for the U.S. Navy at the Massachusetts Institute of Technology. The Whirlwind was a flight simulator that could locate objects. Slide 5: In 1965, IBM created the first graphic display machine. The IBM 1130 computer was used with the IBM 2250 display unit. The IBM 2250 was a cathode ray tube (blank screen TV), which used programmed software from the IBM 1130. The images were drawn on a screen using a light pen and displayed vector graphics. Slide 6: Graphics card: Graphics card or video card is display adaptor or hardware component whose function is to generate output images to display. It is also called as dedicated expansion card. Slide 7: Components of Graphics Card: 1. Graphic Processing Unit (GPU) 2. Video Bios 3. Video Memory 4. RAMDAC 5. Mother Interface 6. Cooling Devices 7. Outputs Slide 8: 1. GPU – Graphics Processing Unit : A GPU is dedicated graphics processor optimized for floating point calculations which are fundamentals to 3D graphics rendering. The main attributes of GPU are core clock rate which typically ranges from 250 MHz to 1600 MHz (speed depends upon memory type),and number of pipelines (vertex and fragment shaders) which translate a 3D image characterized by vertices & lines into 2D image formed by pixels. Slide 9: 2. Video Bios : The VIDEO BIOS or FIRMWARE contains basic programs that governs graphics card operations and provides the instructions so that computer hardware and software can interact with card. It contains information on memory timing, voltage of graphics processor and RAM, operating speed and other information. Like our motherboard BIOS, it is possible to change VIDEO BIOS of our graphics card, but it is recommended that it should be done under experts supervision, since changing VIDEO BIOS may improve your graphics cards graphics performance. Slide 10: 3. Video Memory : An IGP uses RAM of main memory, while Graphics card has its own memory called as Graphics memory or video memory. The memory capacity of most modern video card ranges from 128 MB to 1 GB. Since video memory needs to be accessed by GPU and display circuitry it often uses special high speed memory. Around 2003 the video memory was based on DDR technology was very low and also performance was poor. During and after that year, manufacturer moved towards DDR3,DDR3,GDDR3,GDDR5 technology. Now there are improved graphics card with better memory and better clock rate (speed) are available whose speed ranges from 400MHz to 2.5 GHz. Slide 11: 4. RAMDAC : RAMDAC is Random access Memory Digital To Analog Convertor which converts digital signal to analog signal for use by computer display which uses analog input such as CRT displays. Due to growing popularity of digital display it has mostly disappeared as discrete component. Almost all current LCD,PLASMA displays and TV’s works in digital domain and do not requires RAMDAC. Slide 12: 5. Motherboard Interface : It is the connection system which connects graphics card with motherboard system. Although there are many connection system since 1974.Nowdays AGP and PCI-Express slot are most widely used connection system. 6. Cooling Devices: Graphics card uses lot of electricity which is converted into heat. If heat isn’t dissipated then card could get overheated and get damaged. Cooling devices are incorporated to transfer heat elsewhere. PCI Slots AGP Slot Slide 13: 7. Outputs: These are the connection system which connects graphics card with display. 1. VGA : Analog based standard adopted in 1980s designed for CRT displays. Also called as VGA connector. 2. DVI: Digital based standard designed for flat panel screens such as plasma,LCD display, video projectors,etc.This DVI port is used for HDTV. 3. S-Video : These digital based VIVO are used in televisions, video recorders, gaming consoles,etc. Some modern graphics card also provides HDMI ports that enables user to switch to high end gaming and high definition movies. Slide 14: Why graphics card is important ???? Slide 15: Very poor reflections No glow in surrounding Low Graphics of game without Graphics card : Poor depth of field Slide 16: Clear reflections Glow in surrounding High Graphics of game with Graphics card : Clear depth of field Slide 18: Advantages of Graphics Card : Anti Aliasing : While dealing with images, aliasing artifacts can appear as bands.Anti Aliasing is technique used to counter distortion caused by aliasing effect. Motion Blur : This technique is used to blur objects in fast motion. Slide 19: 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. Slide 20: 6. Anisotropic Filtering : This technique enhances quality of textures at oblique viewing angles. Poor texture quality Detailed textures Slide 21: 7. Pictures comes true : High Definition effects can be added to images so that they looks like real photos. Slide 22: Instructions to install graphics card : 1. Remove your current drivers (read how to remove drivers under the drivers section).2. Open up your case3. Take out your old card4. Pop in your new one(Make sure it's the correct one)5. Lock your case back up6. Boot up7. Install new drivers from the video card brand website (ATI/Nvidia) the drivers on the disk provided are usually out of date.8. Reboot after drivers are installed Slide 23: Applications of Graphics card: 1.Paint Programs: This allows you to create freehand drawing. Slide 24: 2.Creating 3D models using CAD software Slide 25: 3. For creating Animations : You do not have the permission to view this presentation.
