Curve/Utility/Simplify

The Simplify Curve tool in Grasshopper is under the Utility tab in the Curve menu and is an easy tool that simplifies complex polylines and curves in Rhino. To use the tool, you should first have a curve or polyline in Rhino that has an excess number of control points. You then open up Grasshopper, choose the Simplify tool, and link the Curve to the (c) input. The (t) input controls the deviation tolerance and the (a) input controls the angle tolerance. You must define a number for each of these inputs or, as I did, use the slider tool to be able to easily alter these inputs. When you use a high number for the angle tolerance and the deviation tolerance, the curve becomes simplified and control points are removed. I also used the Move tool to be able to see the result of the simplification next to the original.

Geometry, tessellations, and folds are fascinating subjects to study. Their ubiquitous presence in a wide range of fields demonstrates their usefulness as well as their beauty. The folding and unfolding of materials, especially when in tessellated, regular patterns, creates dynamic structures and designs in nature, fashion, and architecture.

The way mathematics formulates these shapes, patterns, and folds is both simple and intriguing. The same methods of tessellation, folding, and unfolding can be translated easily into architecture. One could conceivably create an interesting, structural, parametrically designed skyscraper from these methods. The 132 5. Issey Miyake collection of clothing accomplishes a similar goal in fashion design. The designers used a computer modelling program to design the three dimensional forms of the garments, which are then modeled in paper adding cuts and fold lines until the forms can be flattened.
