From recent lecture video,

what is the difference between u and up vector?

And also, could you upload the lecture slides for the video? Thanks!

Uploaded lecture slides.

 

The difference between v (not u) and up:

- v is the actual y-axis of the camera

- up is a general up direction of the camera specified by the programmer. it is not identical to v in general.
