+##### Parametrisierung
 In einem früheren Kapitel haben wir gesehen, dass NURBS Flächen durch eine Serie von NURBS Kurven in beiden Richtungen definiert sind. Diese Richtungen sind mit U und V benannt und ermöglichen eine NURBS Fläche entsprechend einer zweidimensionalen Domäne zu parametrisieren. Die Kurven selbst werden als Gleichungen im Computer gespeichert, wodurch die resultierende Fläche mit beliebiger Präzision berechnet werden kann. Das Verbinden zweier NURBS Flächen wird in einer Polyfläche resultieren, in der verschiedene Schnitte der Geometrie verschiedene UV Parameter und Kurvendefinitionen haben werden.
 
 Polygonnetze auf der anderen Seite werden durch eine konkrete Anzahl von genau definierten Eckpunkten und Netzflächen bestimmt. Das Netzwerk von Eckpunkten wird generell nicht mit einfachen UV Koordinaten beschrieben werden können. Die Darstellungspräzision kann nun nur durch Verfeinerung des Polygonnetzes oder das Hinzufügen weiterer Netzflächen verbessert werden, weil die Netzflächen die Darstellungspräzision durch ihre Darstellung klar definieren. Das Fehlen von UV Koordinaten jedoch ermöglicht es, Polygonnetze komplizierterer Geometrie flexibel in einem Polygonnetz handzuhaben, statt wie beim Fall der NURBS Darstellung auf eine Polyfläche zurückgreifen zu müssen.

Es ist kein umfangreiches Buch über Elektronik (da es bereits eine Anzahl großartiger Ressourcen zu diesem Thema gibt). Stattdessen fokusiert sich das Buch auf die Erkundung der Produktentwicklung.

 ## Grasshopper - an Overview
 
-#####Grasshopper is a visual programming editor developed by David Rutten at Robert McNeel & Associates. As a plug-in for Rhino3D, Grasshopper is integrated with the robust and versatile modeling environment used by creative professionals across a diverse range of fields, including architecture, engineering, product design, and more. In tandem, Grasshopper and Rhino offer us the opportunity to define precise parametric control over models, the capability to explore generative design workflows, and a platform to develop higher-level programming logic – all within an intuitive, graphical interface.

 To Launch Grasshopper, type Grasshopper into the Rhino Command line. When you launch Grasshopper, the first thing you will see is a new window floating in front of Rhino. Within this window you can create node-based programs to automate various types of functionality in Rhino. Best practice is to arrange the windows so that they do not overlap and Grasshopper does not obstruct the Rhino viewports.
