Box Morphing in Grasshopper. Part 1 – basics of the basics.
Box morphing allows you to transform geometry from a reference box (usually the bounding box of this geometry) into a target box, but this box can be, as it is covered in Part 2, a so-called twisted box, where the sides of the box are no longer parallel. In Part 3 and 4, we’ll se how we can use this technique to panel geometry on a surface.

Intro lugins to demonstrate the Gumball transformation control.

Usage: Click this for more information

Moving the Gumball

Three types of transformation controls. To move the gumball, click, drag and release the controls. If you need to reposition the gumball without moving the objects it transforms, tap the CONTROL key while dragging a transformation control.

1. Translation controls:

• Click and drag on one of the arrows. The translation will move back and forth along the line the arrow lies on.

2. Rotation controls:

• Click and drag on one of the arcs.

3. Scaling controls:

• Click and drag on one of the small boxes.
• If you want uniform scaling, tap the SHIFT key while dragging a scaling control.
