ottobyte Posted January 12, 2015 Share Posted January 12, 2015 Hi there, I just wondered if Affinity might ever support these? Many thanks Mike klumme 1 Quote AD 1.4.1 | AP 1.4.1 | ottobyte.com | @ottobyte | MacPro 8x2.8, 8gb, OSX 10.11.3 Link to comment Share on other sites More sharing options...
Staff MattP Posted January 14, 2015 Staff Share Posted January 14, 2015 Hi ottobyte, The back-end already has b-splines and can render them to the screen. Our curve classes already load and save b-spline data. We don't have a tool to create them yet, but I haven't overlooked them - they've been in the code for at least a few years now and a tool will exist at some future point - but there has been strangely little interest in them to this point, hence why I haven't made it a priority yet... Thanks, Matt Quote Link to comment Share on other sites More sharing options...
ronniemcbride Posted January 14, 2015 Share Posted January 14, 2015 I'm a bit curious to know what exactly would the implementation of b-splines would be used for besides the exporting paths to a 3D application. Ottobyte could you please explain your use. Thank you! Quote LEARN AFFINITY DESIGNER TODAY.

Staff MattP Posted January 14, 2015 Staff Share Posted January 14, 2015 It's just a different way to draw - some people find it suits them better... Quote Link to comment Share on other sites More sharing options...
Sven Kalkschmidt Posted January 14, 2015 Share Posted January 14, 2015 I know next to nothing about Bezier curves and B-Splines, but would this be a correct example of B-Spline drawing? https://www.youtube.com/watch?v=X0uurzdHzHI Quote Link to comment Share on other sites More sharing options...
Staff MattP Posted January 14, 2015 Staff Share Posted January 14, 2015 Yes, that's a b-spline curve :) Quote Link to comment Share on other sites More sharing options...

ottobyte Posted January 14, 2015 Author Share Posted January 14, 2015 Thanks for all the replies! Yes It's just a different way to draw for me. There is a particular task I am doing now which is becoming very awkward to get the fluidity in the curves I want to achieve. A couple of years ago I had some success using them in Inkscape, I tried that again yesterday and the app has to be the most unsatisfying environment to work in of all time - to make matters worse, it appears to run slower on OS X than it ever did! I digress. @Matt, that's great that you already have the architecture in place. Well I'll be happy to wait until you guys have the time to add them, would be very useful, as apart from Inkscape or 3D modelling software, no OS X app seems to have them.

ronniemcbride Posted January 14, 2015 Share Posted January 14, 2015 Yes, Petar_MK that is b-spline. I never experience the use of b-splines in a 2d vector application. I not saying that it not a great approach I just saying I always have related it to being more powerful in a 3d application because the control vertices are usually offset from the spline curve or surface of the line. This makes sense to me when referring to the surface of a 3 dimensional shape. I had to look this up to see b-splines being used in practice in a 2D application to understand its power. I found this and was like wow that actually a pretty nice approach as well. Link: https://www.youtube.com/watch?v=BZ4jxfxaCXo I know smart mode is not based on b-splines but this topic made me think perhaps I should make myself more acquainted with this approach Thanks for bring this topic up.

ed_in_nj Posted July 25, 2018 Share Posted July 25, 2018 I realize this is an old topic, but I would interested to see an implementation of a B-spline tool in Designer. I'm new to this program and am working thru the learning curve. I come from 'Corel Draw' where I have done 2D maps with topographic lines. In my workflow, B-splines are easier (for me) than Bezier curves. Anyway, I like the program and I'm hoping it will allow me to abandon my use of Corel Draw as I become more familiar with it. Thanks to the developers....and thanks for adding the iPad version (which I have yet to use, but I'm looking forward to trying). -Ed Quote Link to comment Share on other sites More sharing options...
