Reading : Grasshopper Primer ‘0.1, 0.2, 1.1, 1.2′

– GH was invented trying to develop Rhino’s history tree more explicitly to editing in detail and empowered the user to develop logical sequences beyond the existing capabilities of Rhino’s built in features

-The geometry preview we see is a lightweight representation of the solution and it automatically updates.

-Algorithms are step by step procedures designed to perform an operation.

-You use Grasshopper to design algorithms that then automate tasks in Rhino3D.

-An easy way to get started if you are unclear how to perform a specific operation in Grasshopper would be to try manually and incrementally creating an algorithm using Rhino commands.

 

• File-> Preference to adjust settings

Author: set personal metadata which will be stored with each GH document

Display: fine grain control over the look and feel of the interface

Files: specify things like how often and where to store automatically saved file

Solver: manage core and third-party plugins

• Alt+Tab to quickly switch between any open Grasshopper documents

 

MODE LAB Parametric Design Fundamentals

• Parametric: when expressing explicitly a set of quantities, the variables that expressions are in terms of independent are known as “parameters“
• Parameters are meaningful properties of design; add definition and boundary to design
• Parametric design results are explicit
• Parametric principles

• Modeling tools: 3ds Max, Maya, Revit, Fusion 360, DesignScript, Vasari, Dynamo, GH…

 

Mode Lab Intro to GH

01

           changes of parameter => changes of overall form

• PARAMETERS, instead of shape, is defined
• process is EXPLICIT so a clear understanding of the geometry and how to model it is important

02

syntax based (code) vs. node based (GH), GH is a visual programming tool

03

Container takes element from Rhino to be used

Constructor define an element (eg. in the pt constructor, move mouse to input and right click to set #, or use # slider alternatively)

Save both 3dm and gh files and reopen to maintain relation

04

05

moving a parent object in GH creates a new object bc. cannot define the geometry to move AND define the geometry as the end point (yellow)

Do this by selecting the box, then go to Edit -> Group => a white box, then right click on white box to lable

Creating a list: Params ->Input -> Panel and connecting an out put to the Panel to see list

three kinds of data matching in GH

06

Sets-> Sequence -> Range

range and domain

create pt w/ coordinates: Vector -> Point -> Point XYZ

Maths -> Trigs -> Sine

Enable vs. Preview: turning off Enable breaks off the entire tree’s preview whereas turning preview off allows related parameters to still be viewable

07

Vector-> Point -> Point Polar 

Maths-> Util -> Golden Ratio
