CS559 Midterm Exam

The CS559 Midterm exam will be held in class on March 28.

The exam will cover all topics covered in class till curves; texture mapping is not included. Related textbook sections and lecture slides are good reading resource.

What willl definitely not on the exam:

• Anything about FlTk
• The syntax of OpenGL commands

Kinds of things you might get asked (you should know)

• the concepts of light and eye
• the image formation principle of a camera
• convolution: definition and how to compute it, how to smooth and sharpen an image, how to detect an edge
• resample: how to down-sample and up-sample an image, what are the common reconstruction kernel
• trichromacy -- why 3 colors are enough to represent all color to human eyes
• the concept of color space
• the concept of image warping and morphing
• 2D/3D transformations and their properties
• projective transformation and its properties
• the basic graphics pipeline from 3D to 2D images
• rasterization -- using incremental computation for speedup
• basic ideas and methods for anti-aliasing
• Z-buffer and BSP tree
• matrix stack and how to concatenate basic transformations to achieve a complex motion 
• Phong shading model: what are emissive, diffuse, specular terms for?
• concept of BRDF
• concepts of flat shading, difference between Gouraud and Phong shading interpolation
• different curves covered in class (no need to remember resulting coefficients, but need to know the properties of different curves, and the basic procedure of deriving them)
• texture mapping will not be included. 

For your reference, previous years' exams are accessible here

• 2006 Midterm Final (w/Key)
• 2005 (Midterm w/key) (Final w/Key)

Please keep in mind that we cover slightly different material and our exam time is shorter. So you can expect less (and different of course) questions.
