Can you add some context on what T-splines are and why it's a big news? I kinda know splines in a trajectory planning sense but never heard of T-splines. Thanks!
The important part is that compared to B-splines, it lets you reduce the data size of a closed form surface by reducing the amount of data needed to describe it.

The first 3 pictures explain it better than I can describe it, the rest is math going into how it's implemented.
