782: Midterm Notes
General Notes
- Know terms (e.g., BRDF, radiance, power, irrandiance, Fresnel, just noticable difference, chromaticity, etc.)
- Be able to explain equations (not memorize them).
- On the midterm: material covered in slides and related material from book (if a topic is not coversed in the slides, don't worry about that material in the book)
- NOT on the midterm: PBRT, implementation issues related to labs.
- "short essay" type questions - e.g., explain this, describe that, how would you do X, what would happen if ....
- The list below is not meant to be exhaustive, but rather representative (i.e., it's supposed to give you a good idea of the topics we've covered, but just because something is not on the list doesn't necessarily mean it won't be on the midterm - review the slide sets).
- Percentages are *estimates* of emphasis on midterm
