Many tween curves at once?

Grasshopper
1

Hi,

I have been experimenting with tween curves and I was wondering if I can do more than one at at a time? Like say ok these are my two curves and now give me 20 curves in between.

Since I could not figure it out I made a sketch with grasshopper and an endless amount of number sliders to get to my curves. but if any of you knows how I can do it better, I am supper happy for advice.I am talking about the group with the red background. As my first attempt with the linear array was not quite what I was looking for. I want my curves to gradually change.

no geometries internalized in your GH file:

please right click on both of them, chose “internalise data”, save file and repost :+1:

…red background? :slight_smile:

yes, red background, and internalized curved. it is all there, but not saved correctly, sorry, luckily i had not closed the window: so here it is again:

Looks like the same curves in @inno’s image are still not internalized.

I found this collection of curves in the red group but no preview was enabled. Make it easier for your audience!

There are better ways than sliders to get a series of numbers:

oh dear, sorry for the mess, attempt no. 3

and thanks for the series component, I already thought all these sliders could not be a good solution. this is so much more elegant

ah, but I just realize I cannot plug the panel output into the factor input of the tween curve component. any suggestions for that?

8

ok, my numbers were higher than 1 and “factor” may not be higher than 1. Thank you this is the solution

Series and Range are both good at getting a sequence of numbers. Then ReMap and Graph Mapper and other components can manipulate them.

Of course you can. Why have duplicate values though? Avoid running data through text panels.

Great, thanks! i did not know about entwine.

Is there a way to connect the end of two subsequent curves, now? I want to do that so I can later turn them into planar surfaces and extrude. I know how to manually do it in Rhino, but Grasshopper … no idea.

Connect Curves, but it’s not as simple as you might think, in part because of two branches:

Would be easier (?) to Weave (or Sort) the tween values first:
