I have posted another tutorial video. This time about arc-length parameterization.
It’s a concept that was not covered well in class. The video will show the basic concept a different way, as well as give you an idea on how to compute it in practice for a complicated curve (which will be useful for the project).
The video is on media space at: https://mediaspace.wisc.edu/media/t/1_wrarin8j
As an experiment, I’ve also put it online at: https://graphics.cs.wisc.edu/Courses/Graphics14/VideoTests/arc/, this viewer allows you to watch at 2x speed, although it doesn’t work in all browsers.
