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

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.

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.

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. This is a very interesting conversation.

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).
