using defined curves as parameter inputs

[Mr. Daniel Floden 0]

Hi

 

I've tried to understand how to do this the most straight forward way but I cannot find the suitable functions for it.

I want to do a generic curve with x and y inputs. And the x and y needs to be functions of a number of predefined B-spline curves.

So if I for instance would like to set x as (A^2 * sin B ), where A and B are predefined B-spline curves in my project. How do I do this the most effective way by feature programming?

Hey Daniel,

 

You can find a sample project 'genericcurve' and find it attached (documentation Browser-> Samples -> genericcurve).

 

Additionally I attached a project file (GenericCurveFtrDef) with your specifications.

 

Best Regards

Hi Daniel,

In principle you have to be aware if you are using f(t) or f(x(t)). If you are mapping x=t you can speed up your function. This is possible by using Greville spaced bspline points, see picture below

 

 

I found this excerpt on https://syllabus.byu.edu/view/SnfjQFxAdIyY.html#scheduleContainer chapter 6 on bsplines. There are more sources if you search the internet.

 

Have fun
