Information

Pufferfish

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

This plugin is a set of 131 components which focuses on Tweens, Blends, Morphs, Averages, & 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 a few extra components which simplify some common grasshopper operations such as testing for equality with the option of tolerance and reparameterizing numbers. 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 more similar to Rhino's tweens.
  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 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.

 

Pufferfish Changelog

Jan 03, 2018 - Pufferfish V1.7

  • Update to add 7 new components. Components from the Discrete Vectors plug-in (http://www.food4rhino.com/app/discrete-vectors) have been updated and are now a part of Pufferfish. Other minor updates and fixes. Some components require at least Rhino 5 SR12. After installing the pufferfish1-7.gha, please close Rhino completely one time to avoid potential assembly reference errors with the "Twisted Box" components.

Dec 29, 2017 - Pufferfish V1.6

  • Re-uploaded Pufferfish V1.6 to fix a bug in the corner orders of Twisted Box components that use surfaces.

Dec 22, 2017 - Pufferfish V1.6

  • Re-uploaded Pufferfish V1.6 to fix a bug with the Point Divide Curve Target component.

Dec 20, 2017 - Pufferfish V1.6

  • Update to add 6 new components like Twisted Box Through Surfaces and Twisted Box Through Meshes with interpolation options. Tween Mesh and Tween Surface components now have interpolation options. Some component name changes, icon changes, updates. Some components require at least Rhino 5 SR12. After installing the pufferfish1-6 gha, please close Rhino completely one time to avoid potential assembly reference errors with the "Twisted Box" components.

Dec 04, 2017 - Pufferfish V1.5

  • Re-uploaded Pufferfish V1.5 to fix a bug with the Move2Pt component not moving certain geometry types.

Nov 29, 2017 - Pufferfish V1.5

  • Re-uploaded Pufferfish V1.5 and its examples to include 3 forgotten Twisted Box components. Twisted Box Array, Construct Twisted Box, and Deconstruct Twisted Box.

Nov 28, 2017 - Pufferfish V1.5

  • Update to add 41 new components. The new components are primarily focused on a new tab for "Twisted Box" components. Additional various components added to the other tabs. Some updates to existing components. Some new components require at least Rhino 5 SR12. After installing the pufferfish1-5.gha, please close Rhino completely one time to avoid potential assembly reference errors with the new "Twisted Box" components.

Nov 08, 2017 - Pufferfish V1.4

  • Update to improve algorithm for all "On Curve" components and all components with an "Interpolation Type" input.

Nov 01, 2017 - Pufferfish V1.3

  • Update to fix a minor bug in all tween plane components with Quaternion rotation that would result in null planes when input planes X axis's aligned. Added many new examples.

Oct 28, 2017 - Pufferfish V1.2

  • Update to add 9 new components. 3 for tweening planes on curves with Quaternion rotation, 3 for tweening planes on surfaces with Quaternion rotation, 3 for tweening points on curves (like Grasshopper's evaluate curve component except you can interpolate between user defined points on the curve rather than interpolating the entire curve) . Added tolerance input to "Is Arc/Circle/Ellipse" component.

Oct 22, 2017 - Pufferfish V1.1

  • Minor update to add Quaternion rotation option to the Tween Planes components for smoother tween rotations and prevention of Gimbal lock. Suggested by Andrew Heumann, based on a grasshopper definition by Daniel Piker.

can get a tutorial for this toolset? It would be super helpful for people who are just starting out. I have some experience with GH and Maya but I am not able to get the results that are uploaded on…Continue

@Kourniatis Nikos Most likely in the next updates. I have a bunch of stuff in the works - whats here now was just polished up to get V1.0 out there. Otherwise, I would keep making forever and never actually release it:D

Good evening!

Does it work for polysurfaces or breps?
