Introduction to Grasshopper
- Introduction to Grasshopper: what is parametric design? What is Grasshopper?
- Software installation: where to download and how to install Grasshopper
- Launching Grasshopper and understanding the Grasshopper interface
- About the software
First Steps in Grasshopper
- Starting with Points: create a point and control it's position parametrically
- Curves, Lines and Splines: use your point for a curve or line
- Data Matching: how to combine lists and make multiple objects from one component
Functions and Control
- Series, Range and Domain: generate multiple objects into lists
- Functions: use a math function to draw a curve
- Control and Lists: select items from a list, so you can handle them individually
- Transformations: moving, rotating or scaling objects from a single component
- Graph Mapper: tweak the shape from a series of numbers graphically
- About Functions & Control
Example: Panelling to place elements over a surface
- Import Geometry from Rhinoceros into Grashopper
- Sub-divide the Surface: create parts from a single surface, using domains
- Twisted Boxes: twist and deform a box volume to follow a smooth surface
- Morphing Reference Geometry: deform geometry to follow the twisted boxes
- Morphing Example continued: finishing with multiple variants
Example: Twisting Tower: a complete Skyscraper concept from scratch
- Introduction and Project Reference: Turning Torso by Santiago Calatrava (Sweden)
- Floor outlines: translating a series of planar curves into groups of floors
- The Central Core: the elevator shaft from a simple extruded planar curve
- Twisting the Curves: rotating the individual floors around a vertical axis line
- Floor Thickness: extruding planar curves into solid volumes
- Calculating the Façade: preparing the façade surface using a loft component
- Calculating the Façade: continuation: effective use of domains and series
- Reflecting on the result: an overview of the result and adding some color
Diving into the Data Trees
- Data Trees: Introduction, Grasshopper Data Tree diagram and Param Viewer
- Flatten, Merge and Graft: manipulating the list by restructuring the data tree
- Connect corresponding points on Curves: applying the Data Mapper and Flip Matrix
- Diagrid: structuring a surface with diagonal truss profiles
- Diagrid: continuing and finishing the previous example
- An alternative approach for a Diagrid: a façade two diagonal smooth curve pipes
- How to connect one parameter with two different ranges? Using a Remap component
