This page was last updated: March 10, 2009

Test date and time:

Test rules:

1. This is Test #2, not a comprehensive final. However, . . .
2. . . . I reserve the right to re-use a verbatim question from Test #1.
3. The test is worth 100 points.
4. Closed book, closed notes.
5. You are responsible for (1) what is in all handouts, (2) what was said in class, (3) what you have done in the projects.
6. The test is designed to be done in one hour, but you will have the full 90 minutes.
7. The test is over promptly at 11:00. Only the tests that have been turned in by then will be graded.
8. No make-up tests.
9. I do re-grades, but the entire test gets re-graded

The test can potentially cover any of the following topics:

• Texture mapping: general concepts, how we get it, why we want it, what it gets us.

• Terrain visualization. Assigning texture coordinates. Height exaggeration for visualization. Height exaggeration for lighting. Pseudo-lighting.

• Direct volume rendering. Transfer functions. Volume rendering using parallel texture planes.

• OpenGL lighting. How do you get it? Wat does it do for you? What simplifications can you do?

• Stencil buffer. What is it? How does it work? What can you use it for?

• Accumulation buffer. What is it? How does it work? What can you use it for?

• OpenGL Shaders. What parts of the pipeline can they replace? Why does anyone want to do this? What vis things can you do with this?

• Spline curves. Bezier curves, Coons curves. Use of Coons curve in keyframe animation.

• Delauney Triangulation. What is it? What does it tell you?
  Voronoi diagram. What is it? What does it tell you?
  Re-sampling. Interpolated scalar values within a triangle.

• Ethics in Visualization. Kantian, Utilitarian, Intuitionism, Case Study. Visualization vs. Conceptualization.

• OpenDX. What is it? How do you use it?

• More Information about visualization and computer graphics.
