Notification• There are no official course prerequisites. • [Warning] However, we assume in CS380 – programming experience in C (or C++):

not teaching basic programming skills, C/C++ language, Visual Studio, Compiler, etc.

– Note that we only support the Windows environment in the lab!!!

– a good knowledge of linear algebra:not teaching general mathematics

– an exposure to calculus and image processing:not teaching computer vision

What is Computer Graphics?• Imaging = capturing 2D images• Modeling = creating 3D objects• Rendering = generating 2D images from 3D models• Animation = simulating changes over time

Research in Computer Graphics

Image User: How will the image be perceived?

Image Creator: What controls are available?



• 2D imaging– Digital imaging/filtering– Color transformations– Display technology– Compositing and layering

• 2D drawing– Sketching, illustration– User interface

Historical Perspective • A short history of graphics:

– 1950: MIT Whirlwind (CRT)– 1955: Sage, Radar with CRT and light pen– 1958: Willy Higinbotham “Tennis for Two”– 1960: MIT “Spacewar” on DEC PDP-1– 1963: Ivan Sutherland‘s “Sketchpad” (CAD)– 1969: ACM SIGGRAPH founded– 1968: Tektronix storage tube ($5-10,000)– 1968: Evans & Sutherland (flight simulators) founded – 1968: Douglas Engelbart: computer mouse– 1970: Xerox: GUI– 1971: Gourand shading– 1974: Z-buffer– 1975: Phong shading model– 1976: First animations rendered– 1979: Eurographics founded– 1980: Whitted: Ray tracing

Historical Perspective • A short history of graphics (Cont.):

– 1981: Apollo Workstation, IBM PC– 1982: Silicon Graphics (SGI) founded– 1984: X Window System– 1984: First Silicon Graphics Workstations (IRIS GL)– Until mid/end of 1990s: Dominance of SGI in the high end

• HW: Reality Engine, InfiniteReality, RealityMonster, ...• SW: OpenGL, OpenInventor, Performer, DigitalMediaLibs, ...

– End of 1990s:Low- to mid range taken over by “PCs” (Nvidia, ATI, ...)• HW: Fast development cycles, Graphics-on-a-chip,...• SW: Direct3D & OpenGL, computergames

– 1995: First feature film “Toy Story”– Today

• Programmable graphics hardware, Cg, Cuda• Realtime Ray Tracing

What We Are Doing Underneath

What we are going to do in this course• Taking both lectures and lab courses (either lab A or B will

be assigned to you by the TA today)– Checking attendances for both lectures and labs

• Programming homework every week! (you will do your homework in the lab courses)

• Quiz at the beginning of every lecture!

• Midterm and final term examinations (all about math in graphics, not open-book, no memory test!)

• Let’s have fun! J

Grading

• Class participation: 10%

• Midterm/final exam: 50% (25% each)

• Programming assignments (about ten HWs): 30%

• Class quizzes: 10%

• An assignment after its original due date will be

degraded from the marked credit, e.g., A à B.

• Plagiarism will not be tolerated (plagiarism

detection software will be used.)

• No grade for copied codes is given!
