algorithmic modeling for Rhino

Information

Pufferfish

The Pufferfish is one of few animals which is capable of changing its shape.

This plugin is a set of 172 components which focuses on Tweens, Blends, Morphs, Averages, Scales, & Interpolations - essentially Shape Changing. These components are accompanied by support components which are useful methods for the preparation of tween/blend operations such as making polylines compatible and matching surface structures. In addition, there are extra components which simplify some common grasshopper operations such as testing for equality within a tolerance and rounding to nearest numbers. Please email me if you find any bugs to help make this toolset better for the GH community. Works with Grasshopper for Rhino 5, Rhino 6, and Rhino Mac.

Pufferfish Info

General notes

  1. Grasshoppers native "Interpolate Data" component can "Tween" simple data types such as numbers, colors, vectors and points already. Pufferfish's Tweens of these types differ in 2 ways. The first being that Pufferfish has 3 types of tweens for each: Tween Two, Tween Consecutive, and Tween Through which perform the tweens in different ways with the input lists. The second difference is that Pufferfish uses interpolation types which match nurbs interpolation for simple data types. Those types are Linear, Chord, Square Root, and Uniform. Grasshopper's "Interpolate Data" component uses  Block, Linear, Cubic, and Catmull. Pufferfish also adds the ability to tween Planes, Surfaces, Meshes, and Twisted Boxes as well as average them.
  2. Grasshopper already has a native "Tween Curve" component however, it gets odd results sometimes, specifically when tweening polylines. Pufferfish corrects this with automatic internal polyline and curve compatibilization so that the results are similar to Rhino's tweens. Pufferfish tween curve components also have different interpolation types as well as optional refit and sample point methods.
  3. Meshes must have the same topology to tween. Unlike surfaces, meshes which come from two different sources with different topologies are almost always impossible to rebuild (automatically) to have the same topology and point order for a meaningful looking tween. Please do not ask for this feature unless you can provide some information / documentation about how to do so. As recommended by Autodesk Maya for blending meshes "A common blend shape technique is to create duplicates of a base, deform the duplicates, then use them as targets. For example, you might make several copies of a face, and then alter the copies to create a smiling face, frowning face, a crying face, and so on."
  4. A few minor components may exist in some form elseware in other plugins (it's impossible to check them all). If they are in Pufferfish it is because I felt they are necessary to the workflow and I cannot ensure the user has other plugins installed. For example, Pufferfish has a type of "Rebuild Surface" which varies slightly from but exists also in Lunchbox and Peacock.

Hi martin

The squid is because I used a mesh. With mesh it is easy to tween shapes like that (you can make your parts as mesh). The downside of mesh tweens is that they must have the same topology (common in blending through out must software). The downside of surface is there is no robust way to tween trimmed surfaces (even try Rhino's TweenSrf command will give you the untrimmed tweens). Especially if the trim data between multiple trims is very different. (what if one has holes and one does not  - for example ) In your case, it seems the surface edges are relatively similar. You could loft surface A edges to surface B edges and cut the tween surfaces with that loft. Or intersect the loft with the tween surfaces and make patch surfaces from the results.

Comment by martin on January 29, 2018 at 10:33pm

Thanks for your comment Michael, but I think this command will only get me the top or bottom surface form all along the tween, this for example when iam using diferent surface forms at the top and bottom. My question is because your example tween surface gets from 1 surface form to a different one in the tween proces combining it in the middle; so the tween is neither exactly the bottom nor the top surface form, but more like a combination like the squid example

Comment by Michael Pryor on January 29, 2018 at 12:49pm

Hi martin

Surface tweens work on the untrimmed versions of surfaces. Patch, Boundary, and Planar surfaces result in trimmed surfaces. Rhinos tweensrf command will result also in the untrimmed versions. The way to go about this is to retrim the results. Grasshopper has two components for this "retrim" and "copy trim". Use one of those components on the tween surface results to copy the trim data from either one of your input surfaces. 

Comment by martin on January 28, 2018 at 9:24pm

Hi Michael, first thanks for the pluggin I really like it.

I just have a question, when I tween a surface i get a rectangular tween not the exactly organic shape. I have tried Patch-surface, Boundary surface and Plannar surface directly from rhino. Which surface command should I use? 

Comment by Michael Pryor on January 19, 2018 at 9:45am

Confirmed works for Rhino 6. 

Comment by lv on January 10, 2018 at 2:00am

Thank you for this awesome plugin!

Comment by Michael Pryor on January 8, 2018 at 3:22pm

Hi lv,

Look in the example files "Workflow" folder at the example "Pf_TwistedBoxVariableCurve"

Comment by lv on January 8, 2018 at 1:37pm

Hi,

I would like to change the size of the twisted boxes along one curve. In this example I deconstructed the twisted boxes and moved the corners nearer to the curve. However, by scaling the boxes fit not together anymore. Is there a way to merge the corners of the boxes so that the geometry matches perfectly together?

Thank you in advance
