Parametric Modeling with Grasshopper
, lines, curves, and surfaces in Grasshopper Contents Grasshopper is a visual programming interface for the 3D modeling program Rhinoceros. Rhino uses non-uniform rational B-splines (NURBS) to precisely, mathematically model geometry.
This tutorial is an introduction to modeling basic geometry - such as points, line, polylines, curves, and surfaces - in Grasshopper. Drop parameters and components on the canvas and connect them together with wires to create node based diagrams that generate geometry in Rhino. Then connect a Number Slider parameter to the input Factor for the Unit X vector to set the length of movement.
