Graphics Questions


(Fall 2015 - Efros & Ng):
These were the graphics prelim topics this year:

Paper (Kopf et al, First Person Hyperlapse)

Graphics rasterization pipeline

Light transport, global illumination

Geometry -- curves and surfaces

(Fall 2010 - Agrawala & Ramamoorthi):
“Exam Topics:

1. Paper presentation
2. High Dynamic Range
3. Textures
4. Reflection”

(Fall 2008 - Barsky & Sequin):
“Exam Topics:

1. What are the key graphics topics/concepts that a 
student would have to know in order to understand this paper?

2. Discussion of the paper, how the method works, and what its 
limitations are.

3. Various ways to construct an interpolating spline through a 
sequence of points (in the plane).  Smoothness, degrees of continuity, 
degrees of freedom, heuristics to set tangents and curvatures.

4. Physical interaction of light with surfaces; what makes an object 
colored?  Abstractions used in CG to describe behavior of reflected 
light, shading models. ”

(Fall 2004 - O'Brien & Sequin):
“Exam Topics:

1. Paper: Energy-Minimizing Splines;
gradient descent, differential geometry, splines.

2. Physical interaction of light with surfaces;
abstractions used in CG to describe behavior of reflected light.

3. Characterization of radiance in a room;
global illumination.

4. Rendering pipeline and raster display;
scan-line conversion of polygons.

5. Different approaches to animation, their pros
and cons for different applications.”
