Pufferfish

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.

Pufferfish Changelog
