It brought me here and made it my second time watching this video (during the first time, I was trying to learn a topic in Computer graphics, and my interest wasn't machine learning then.. Lool). I appreciate this lecture more now!!

Thank you! I'm working on level curve in QGis and I'm using Multilevel b-spline interpolation. What's the difference with B-spline curve? And How does b-spline curve work with level curve (find z=constant)) thank you :)

I have a question about knots. If there are cubic splines with 5 data points, we'll have 2 curves (5-3=2). Then shouldn't the number of knots be 3-two at both ends and one that joins two curves?

In the code for Bezier Surface, your u vector is a column vector (it should be a row vector)

When making surfaces, the corners never move. But, in your chart at 16:05 The corners of the control points are different that the resulting bezier surface. Did I miss something, or is that just a loose demonstration?

At 6:39, the last bullet says Bezier surface of degree (m,n) were n is the degree of curve on x direction and m is the degree of the curve on the y direction. This seems backwards to me. Why is it correct?
@diodin8587

I thinks the slide was wrong. The next slide says a degree (m, n) surface's x-y coordinates shape is (m+1)x(n+1).

38:35 why can you just set t2 equal to 0? because only then can i get the same matrix form as you do... can you explain why one can do that? is t then element of (0,1)?
@S255fjrbr
5 жыл бұрын
is that why they are uniform and you could just have chosen a T such that t2=0? So you just "shift" it to a convenient value?

Thanks for the lesson... unfortunately, at work I have to develop a spreadsheet for two sequential, 6th-Order b-splines & the associated 1st - 4th derivatives of those 2 sequential b-splines.
