Hi everyone
Is there a way to make this template with grasshopper?
I tried to do this with the pufferfish plugin but failed (also the following template was created with the tweener plugin in Rhino, but if it can be made with Grasshaper it will be very useful or for example this please be added to the pufferfish
That plugin is mis-named in my opinion. That is contours (fields, topography), not tweens (by Rhino’s definition). Cool stuff though.
Here is a quick setup to think of it like topography, refine as needed.
Topo.gh (13.3 KB)
You can get even more refined and custom results by using shader maps (and I believe the Element plugin has a shader mesh to iso curve component). Anyway, the reason it is not in Pufferfish because it is not a tween, it is height-field contouring and there are plenty of ways to do it already (even with just the fields components if you just want to use point locations). What is nice about that plug-in is the editing system.
Indeed.
If we forget C# and particles and this and that … here’s an other (a bit naive) way to cut the mustard: raise the inner crvs, do a Patch (requires 2 steps) and then do the Contours (and project everything back to start Plane).
You can easily do this with Tweener, @architect.civil5 :
No, the Tweener is not mis-named, @Michael_Pryor. It actually does tweens between curves on any surface as in Rhino’s sense, not just contours above a 2d field as in this case. It also does contours easily but is not limited to them.
I don’t know why you’re under the impression the Tweener only does contours. Please look at the examples on https://www.food4rhino.com/en/app/tweener (where we already discussed that misconception in the comments). The main “glass lamp” example shows the surface tweens clearly.
@architect.civil5 's example again, done with Tweener in Grasshopper:
it’s a field, as discussed on the plug-in page (tweening is a made up word from McNeel and it isn’t this). IMO what “tweener” is doing is much more interesting and flexible than “tweening” so not sure why you would want to be so associated with that word but it is up to you as the dev. I like the plugins functionality.
hi @mathias.fuchs is there way to bake result in grasshopper
Tolkien likely invented the word tween. He used it to describe Hobbits in their irresponsible twenties.
“At that time Frodo was still in his tweens, as the hobbits called the irresponsible twenties between childhood and coming of age at thirty-three.”
If we’re being pedantic, the term “tweening” has a long history in animation, which is probably more relevant to the interpolation of curves:
Sure, this is what I understand a tween to be, one thing to the next in sequence, a lot dumber than what Tweener is doing.
Yes haha. Like pre-teen.
Sorry, I just meant that the Rhino command etymology likely stems from that, rather than hobbits. But who knows. I recall the term quite fondly from back in my ActionScript 2 and Maya days 
Yea I knew inbetweens as a term, I thought Rhino was first to nickname it to tweens, thanks for the history lesson.
Regardless what Tweener plug-in is called, dunno if you used it, but it is a quite nice / useful plug-in, deserves more attention than it has.
Thanks for asking, @architect.civil5. If you want to get the actual Rhino curves, for the time being, please use the Rhino command interface instead of Grasshopper.
Either use it in one shot with the single command TweenCurves2 to produce Rhino curves directly, or start an interactive Tweener with Tweener_Start, then edit your curves with Tweener_FishEye and/or Tweener_AddControl if desired, and then export the result to Rhino document curves with the Tweener_Apply command.
As for baking in Grasshopper: I want to add that functionality. I thought about it and will probably add it very soon but I was unsure how users expect it to work:
If you have any preference, I’d be grateful if you let me know! Thanks, M
where I can download this plugin for grasshopper? there’s only rhino version on food4rhino
Hi @mathias.fuchs i think (should the main Tweener components - like TweenerStartFromBrepAndCurves and so on - be bakable, )
Curves TWEEN must be bakable and Curves able to use in other components
But if mesh gradient is too greatly
Thanks for asking, @dfytz1 . What you download from https://www.food4rhino.com/en/app/tweener, or from the package manager in Rhino, installs both the Rhino command plugin and the grasshopper components at the same time.
Please try the new Tweener version 0.3.2001.6789, @architect.civil5 … it has a component TweenerExportCurves . Let me know if it worked for you.
