Raster displays
CS 248 - Introduction to Computer Graphics
Autumn Quarter, 2003
Marc Levoy
Lecture notes for Tuesday September 30
Table of contents:
- Raster displays
- Spatial resolution - How many pixels do we need?
- Frequency sensitivity - sine wave gratings
- Phase sensitivity - vernier acuity
- Temporal resolution - How many frames per second?
Press here for the Powerpoint slides I showed in class
about triads and pixels (HTML or
PPT or
PDF).
For now, ignore the rightmost two columns on the second slide. We'll talk
about subpixel font rendering technology after we've covered rasterization and
antialiasing; it will make more sense to you in a few weeks than it would now.
Section D requires an understanding of Fourier analysis, which we won't cover
until Oct. 9, but in case you're interested...
I didn't have time to cover the remaining sections in class. I'll cover them
next Tuesday, after our discussions of color (which you'll need for your first
assignment).
