A Brief History of Computer Graphics

A Brief History of Computer Graphics

The use of computer graphics can be traced as far back as 1940, when Jay Forrester at M.I.T. designed equipment for training new pilots. The digital computer was chosen as the ideal instrument, because of its adaptability and the flexibility with which the machine could be programmed. It was not until a few years later that a radar defense system project named Whirlwind showed the first practical use of computer graphics (see fig. 1.2). Whirlwind is a computer linked to radar sites, and it displays an electronic map of the location on its monitor with plot blips that represent incoming airplanes. Whirlwind is the first vacuum-tube computer capable of drawing lines and points on a computer screen.

In 1958, an experimental filmmaker, John Whitney, Sr.,created a short animation by using the analog computer to control the movement of the character. Whitney used the same system to create the opening title sequence of Alfred Hitchcock’s Vertigo. Later Whitney and his brother produced more films based on similar techniques.

In 1957, Digital Equipment Corporation (DEC) opened its company with only three employees. Three years later, DEC introduced the PDP-1 (Programmed Data Processor), the world’s first small interactive computer (see Fig. 1.3). DEC has played a huge role in the development of computer graphics. “The Programmed Data Processor (PDP-1) is a high-speed, solid state digital computer designed to operate with many types of input-output devices with no internal machine changes. It is a single address, single instruction, and stored program computer with powerful program features. Five-megacycle circuits, a magnetic core memory and fully parallel processing make possible a computation rate of 100,000 additions per second. The PDP-1 is unusually versatile.

IBM helped General Motors to develop DAC-1 to showcase General Motors’ automobiles at the Joint Computer Conference in Detroit in 1964. The breakthrough came when Ivan Sutherland at M.I.T. created a computer drawing program called Sketchpad in 1961. Sketchpad is the father of all CAD programs. Sutherland created this sketching program for his doctoral thesis at M.I.T. Lincoln Laboratory. Sketchpad allowed users to draw simple shapes on the computer with a light pen. The light pen used a small photoelectric cell in its tip to emit an electronic pulse when the pen was placed in front of a computer screen. Many software companies still use Sutherland’s Sketchpad program’s interface today. This was the first instance in the history of computer graphics that demonstrated the possibility of Computer Aided Drafting and Design (CADD). Sutherland’s Sketchpad was a perfect example of vector-based graphics comprising lines rather than being based on pixels.

The first video game was created by a student, Steve Russel, at M.I.T. in 1961. Spacewar was the world’s first video arcade game that was written for the DEC’s PDP-1. Later DEC packaged Spacewar with every new unit, so the world’s first video game was run on DEC. By the end of the 1960s, CADD began to appear in the mechanical, civil, chemical, and automobile industries. However, such advancement in digital technology had not captivated the field of architecture. The main reason for the delay was perhaps the high cost associated with CAD systems at the time.

Major corporations such as TRW, General Electric, Lockheed-Georgia and Sperry Rand began to use computer graphics. IBM introduced the first commercially available graphics computer, the IBM 2250 graphics terminal, as a result of the new found interest in computer graphics.

In 1963, the mouse was being invented by Doug Englebart of the Stanford Research Institute. At the same time, the digitizing tablet was being developed. Both the mouse and the digitizing tablet are 2D point devices; therefore you need to switch X and Y coordinates to access a Z coordinate. True 3D pointing devices come at a high cost, which is a major reason why the mouse is still a popular pointing device today. Products such as Spaceball by 3Dconnexion or 3D Controller by Logitech prove effective in 3D space. These products enable the user to pan, zoom and rotate 3D models with accurate control of the design process.

To follow is a list of important events in the 1960s that profoundly affected the future of computer graphics.
1961- Whitney produced the title sequence for Alfred Hitchcock’s Vertigo by using an analog computer.
1963- Doug Englebart invented the world’s first mouse. At about the same time, the digitizing tablet was developed.
1966- Ralph Baer at Sanders Associates created a first video game for consumers. The same year, Sutherland at MIT invented the computer-controlled head-mounted display system. Many years later, this device is being used for virtual reality study.
1968- Evan and Sutherland created the LDS-1 (Line Drawing System) for hardware-accelerated graphics. LDS-1 is more than 100 times faster than the IBM 2250.
If the 1960s were an era of experimentation in computer graphics, the 1970s saw the birth of the personal computer. Many theories brought computer graphics to a new level of realism. In 1974, Ed Catmull discovered texture mapping, z-buffers and rendering curved surfaces in his Ph. D. thesis in computer science.

In 1971, Phong Bui-Toung at Utah developed a new shading method that was an improvement on the old Gouraud-shading. Phong’s shading method accurately renders the colors on a mesh surface and produces accurate reflective surface shading, but both Gouraud and Phong’s shadings have difficulties in smoothing over the outline edge of a 3D object.

In 1976, James Blinn of Utah developed a new technique called Bump mapping. Bump mapping can simulate the roughness of a surface by interpreting a grey scale map.

Today you don’t need to develop your own 3D software in order to render realistic images. You don’t have to be a millionaire to purchase a computer that runs 3D software. Creating computer rendering is not an impossible dream, but a reality.

  1. for windows:
    if you've already deleted them they might still be in the recycle bin. empty your recycle bin. or you can go to Start > Programs > Accessories > System Tools > Disk Cleanup to clear temporary files and compress old files. after disk cleanup choose Disk Defragment to further clean your system. this will take a while so close any running programs.

  2. Reboot the router…

  3. Except that this is based on the early 1980s microcomputer revolution, NOT the 1970s. By the way, the game “Diarrhea Dan” is based on a ZX Spectrum game called “Disco Dan”.

  4. you have been awarded 1 sheet of toilet paper!

  5. When it's loading up, keep pressing F8 until the menu comes up, there should be a repair option, try that

  6. i want to play car park!!!

  7. LMAO. What do you think?

  8. Upgrade to Windows Vista.

    http://www.microsoft.com/windows/windows-vista/get/default.aspx

    Sounds like your just trying to add the client of a XP PC to a VISTA PC network with your other computers, this doesn't matter if you have more computers, but it sounds to me liker trying you convert XP TO VISTA. All your client information will follow.

  9. Your cell phone has an email address. It varies by carrier (calling their customer support would be a good idea). You can email the pictures from your computer to your cell phone's email address and you will receive the picture as a picture message on your cell phone. You will want to make sure that you compress the picture size so that your phone can get it. You will be charged for an incoming picture message (assuming you don't have a message plan).

  10. NORWAY!

  11. iogear – search for it, it will do exactly what you want

  12. Syncback SE downloadable at http://www.2brightsparks.com/products.html may help you automate this routine task for you.

  13. in 1:17, look at the joystick, i mean, that looks soooo wrong

  14. WTF was that Edgar Wright on the 2nd scetch the director of Shaun of the dead and hot fuzz.

  15. xaxaxaxaxaxaxaxa

  16. i laughed so much at the 20 second speed chess

  17. LOVE THE NORWEGIAN GAME 1:05

  18. That’s what I thought. Can’t say i’m too surprised though, considering that Peter Serafinowicz is in it as well

    But yeah, IMDB confirms it

  19. I cannot speak for the philippines, but in the United States, there is no license for any of the above. It is an experience driven industry which changes very fast.

  20. DO NOT GET ALIENWARE!!!
    To pricey, building is definently better. If you want a desktop instead of a laptop then -

    AMD or Intel processor – Dual core might be fine since its gaming and school, but go with quad core processor if you have the money.

    Motherboard – Make sure it matches the brand of the processor you bought, and make sure it has PCI-Express 2.0 x16 in at least one slot.

    Memory – DDR2 or DDR3, just make sure it fits. 4 gig+

    Hard drive – Bigger the better, but it can get expensive. 1 Terabyte if you need a ton of stuff stored, but 500 gigs should do.

    Video Card – Mainly better for the gaming, ATI or Nvidia (I find both are good so it doesnt really matter which brand you pick). Just make sure the card is PCI-Express 2.0 x16. Most are now though.

    Power/Cooling – Not very good on these since my purchases normally come with power and a fan/heatsink.

    Optical drive – Just your DVD Rom/CD Rom

    OS – Vista most likely

  21. lol i was taken in for the first minute

  22. No. You would need to install something in order to do that.

  23. Takes the piss out of the 1970s. That’s why I love this.

  24. wow, im pretty sure that wasnt the aim

  25. you could not have enough memory to support your web cam.

    or

    your webcam is faulty. Is the blue screen a quick flash with writing on or a long blank one. If its short ,and you can't read it, make a video and then skip through the video frame by frame to see what it says, it there is a STOP code on it, then yeah its most likey a hardware problem or software problem. again, it could all be your webcam,

    if there is an error or stop code on the blue screen google the code and you chould be able to find out what is wrong

  26. waggle your joystick for suds

  27. It’s Spanish sand.

  28. Fraid not..

    Deskside support is slowly being phased out (where the repair tech comes to your desk). PCs have gotten so "cheap" that it's less expensive for a company to have a few spares on hand, swap out the hard drive and poof! the user is back in business.
    Of course my perspective is corporate customers, I dont know what small businesses do.

    The real opportunity is setting up wireless networks, installing anti-virus and anti-spamware software, developing secure VPNs for mobile employees, and integrating handheld devices (Blackberry and Windows Mobile phones) into the company.

    The tech repair guys (unless you want to strike out on your own and target home and small business users) are low paid employees due to the commoditization of PCs.

    Hope that helps you..

    Good Luck and HNY

  29. Hmm, whole lotta Commodore PETS…

  30. Go to Power Options in the control panel. You will find all the choices there. Power off, sleep, hibernate, stand by, etc.

    Go to help to read about the various options. You can have a complete power off. You can have a mode that stores memory and powers off for a quicker startup. You can have a mode that just puts it in low power mode which starts up almost instantly. I use the last.

    ? ??l???q ?

  31. Compared to an aeronautical, mechanical and electrical engineer, no.
    No idea about the military's policies.

  32. Hmmm – Homework?

    General Hints – you fill in the details

    Dos window
    ipconfig /all
    Ip address?
    gateway?
    DNS servers

    Ping router

    Cable test

  33. Zero X? WTF?

  34. Lol fapping guy and ‘almost like a movie’ >>’

  35. You need to network your PC with hers using an ethernet cable(LAN). Router is optional as it's primarily used for the internet. So, if you are both setup with the internet thru a router or if your just connected together with a LAN cable, then jsut create a network for printer sharing using the Network Setup Wizard in "Network Connections" in start menu or desktop

  36. the Japanese one on the shelf at 1:04 reads ????”Fudou-san” – “Real Estate.” There’s some katakana at the top of the box, but it seems to be nonsense – ??????????.

    The horse one is… confusing.
