It always seemed a little strange to me that the curvature continuity thing hasn’t caught on in graphics. I guess if it’s not getting translated into a surface it’s easier not to notice the kinks. Personally, I’m a huge fan of it, especially when used with more ‘conservative’ profiles (ones more similar to simple fillets). Look at all the current apple products, the corners are pretty close to a regular fillet, but there’s no ugly C1 kink.
Working with Rhino has made me instinctively tense up when I see that kink, even in graphics haha.
