Week 1: Introduction to Grasshopper THE BASICS: POINTS, SLIDERS, LINE, AND SURFACE VOLUMES

The first task we were given for this algorithmic sketchbook was one to introduced the interface and basics of Rhino and Grasshopper, which we will use for parametric modelling. Grasshopper, paired with Rhino allows the relationship between numerous design paramaters to define a parametric model, the parts of which are related and can be modified according to the parameters and dependicies defined.1 1

Ronnie Parsons and Gil Akos, Introduction to Grasshopper,

The steps involved: This introductory task comprised creating 5 construct points and 5 number slider componments set to range from 0-100, to create 4 points in Rhino. When linked by the addition of a Polyline compoenennt in Grasshopper, these points created a credible outline of a building. When the value of the sliders was altered the outline changed accordingly.

Modelab collective, (aired 21 September, 2012) < http://lab.modecollective. nu/lab/introduction-to-grasshopper/> [accessed 1 August 2014].

To create a roof to the building, these previous commands were copied and pasted, but the slider connected to the Z components was set within a range above 1 but less than 100 so as to elevate the form above the â&#x20AC;&#x2DC;ground planeâ&#x20AC;&#x2122;. The building was given volume once the Polyline components were connected to a single Loft component which was then connected to a Cap component. Lofting the structure created a freeform surface. What resulted was a modifiable volume bound by 6 surfaces that changed according to the number sliders, to produce varying shapes. In other words, a parametric building, in which a change of the inputs consequently changes the outputs as the overall geometry is formed by numerous related geometries.

Week 2: Understanding Geometry and Transformations

CREATING A GRID FIG.3 CREATING A GRID IN GRASSHOPPER

This weeks task was to generate a grid with an array of columns extending from it. These columns were to orient their axis according to the relative tangent of the curved surface from which they are extending. Variations to the columns heights and radius could be achieved by modifying the inputs.
