1 Computer Graphics Computer graphics deals with all aspects of creating images with a computer Hardware Software Applications Computer graphics is using computers to generate and display images based on 2D/3D models representing a scenario

2 Charts and Graphs

3 Computer Aided Design (CAD)

4 Virtual Reality (VR)

5 Data Visualization

6 Simulation (Training)

7 Computerized Art

8 Entertainment (Movies)

9 Basic Question and Answer Where did this image come from? What hardware/ software did we need to produce it? Application: The object is an artist s rendition of the sun for an animation Software: Maya for modeling and rendering but Maya is built on top of OpenGL Hardware: PC with graphics card for modeling and rendering

10 Basic Graphics System Image formed in FB Output device Input devices Keyboards, button boxes, dials Mouse devices Trackballs and spaceballs Joysticks Data gloves Digitizers Image scanners Touch panels Light pens Voice systems CRT LCD Plasma

11 Computer Graphics: Computer graphics goes back to the earliest days of computing Strip charts Pen plotters Simple displays using Analog/Digital converters to go from computer to calligraphic CRT Cost of refresh for CRT too high Computers slow, expensive, unreliable

12 Cathode Ray Tube (CRT) Can be used either as a line-drawing device (calligraphic) or to display contents of frame buffer (raster mode) Interior of a cathode-ray tube for use in an oscilloscope. 1.Deflection voltage electrodes 2.Electron gun 3.Electron beam 4.Focusing coil 5.Phosphor-coated inner side of the screen

13 Raster Scan Display TV-standards: -PAL -SECAM -NTSC

14 Computer Graphics: Wireframe graphics Draw only lines Sketchpad Display Processors Storage tube wireframe representation of sun object

15 Sketchpad Ivan Sutherland s PhD thesis at MIT Recognized the potential of man-machine interaction Loop Display something User moves light pen Computer generates new display Sutherland also created many of the now common algorithms for computer graphics

16 Display Processor Rather than have the host computer try to refresh display use a special purpose computer called a display processor (DPU) Graphics stored in display list (display file) on display processor Host compiles display list and sends to DPU

17 Direct View Storage Tube Created by Tektronix Did not require constant refresh Standard interface to computers Allowed for standard software Plot3D in Fortran Relatively inexpensive Opened door to use of computer graphics for CAD community

18 Computer Graphics: Raster Graphics Beginning of graphics standards IFIPS (International Federation of Information Processing Societies) formed two committees to come up with a standard graphics API (1973) Graphical Kernel System (GKS): European effort Becomes ISO 2D standard Core: North American effort 3D but fails to become ISO standard

19 Raster Graphics Image produced as an array (the raster) of picture elements (pixels) in the frame buffer

20 Raster Graphics Allows us to go from lines and wire frame images to filled polygons

21 Computer Graphics: Realism comes to computer graphics smooth shading environment mapping bump mapping

22 Computer Graphics: Special purpose hardware Silicon Graphics geometry engine VLSI implementation of graphics pipeline Industry-based standards PHIGS RenderMan Networked graphics: X Window System Human-Computer Interface (HCI)

23 PHIGS and X Programmers Hierarchical Graphics System (PHIGS) Arose from CAD community Database model with retained graphics (structures) X Window System DEC/MIT effort Client-server architecture with graphics PEX combined the two Not easy to use (all the defects of each)

24 SGI and GL Silicon Graphics (SGI) revolutionized the graphics workstation by implementing the pipeline in hardware (1982) To access the system, application programmers used a library called GL With GL, it was relatively simple to program three dimensional interactive applications

25 OpenGL The success of GL lead to OpenGL (1992), a platform-independent API that was Easy to use Close enough to the hardware to get excellent performance Focus on rendering Omitted windowing and input to avoid window system dependencies

26 Computer Graphics: OpenGL API Completely computergenerated feature-length movies are successful New hardware capabilities Texture mapping Blending Accumulation, stencil buffers

27 Computer Graphics: Graphics cards for PCs dominate market Nvidia, ATI, 3DLabs

28 Computer Graphics: Game boxes and game players determine direction of market

29 Computer Graphics: Photorealism Computer graphics routine in movie industry: Maya, Lightwave Programmable pipelines

30 Display Technology: Liquid Crystal Display (LCD) Plasma Display Panel (PDP) Light-emitting Diode Display (LED)

31 Summary Computer graphics is using computers to generate and display images based on 2D/3D models representing a scenario How to model? How to display / render? Modeling user interaction is important!! Which functions to be provided to the user?
