Handwritten notes from 09-14.
- The console log, which you can usually display with F12, is a good place to see error messages. I'll demo it.
- The program that I worked on last time is in 0914-interactivegreen. Point your browser at a.html. Last night, I rewrote it to:
- Change yellow to green everywhere since it's adding green not adding yellow.
- Put the 2 standard include files in the same dir.
- Now we're starting a module on 3D rotations.
-
My note on 3D rotation.
- All rigid transformations in 3D that don't move the origin have a line of fixed points, i.e., an axis, that they rotate around.
- deriving the vector formula for a rotation given the axis and angle
- computing the matrix from a rotation axis and angle
- testing whether a matrix is a rotation
- if it is, then finding the axis and angle.
