Week 2 Algorithmic Sketchbook

This task required us to use some data in order to create some points in Grasshopper which were then used to construct a surface. Together with fellow peers we sat down and discussed what data we should look at. After brainstorming we decided that analysing data specific to the 2014 LAGI site would be beneficial in understanding how we can you this to generate form.

Based on the Copenhagen wind rose diagram, wind speed and direction allowed for me to evaluate wind patterns and how using this could generate a form that has assessed the efficiency of this source of energy.

This data was set to 3 parameters in order to represent it in grasshopper. Month was set to the X coordinate, average wind speed to the Y and average wind calm to the Z. Average figures for every second month was inputted into these coordinates which generated points that I then put a line through a lofted. This exercise was very useful in putting into practice how data analysis when tackled in a generative approach can derive a form that is performative the site context and conditions.

AA Driftwood Project:

Through the videos in the tutorial this week we were taught how to go about replicating actual design projects.

Using the curves, intersection and transform menu components in Grasshopper.

Experimenting on the components and methods introduced in the Creating Gridshell tutorial. I made my own curves in rhino which I then subdivided and put geodezic curves through to create a gridshell which I then manipulated by changing the parameters.

Creating a pattern by creating a surface and dividing it into cells using a voronoi component which I then played around with the parameters in order to come up with a custom pattern.

Just like the patterning lists task I watch additional video tutorials to experiment with different ways of using the voronoi component and how I can manipulate it. I then offset all the cells to create a structure out of my custom pattern.

The Spiraling video tutorial introduced the use of mathematical components such as pie, and domains to achieve a sprialing effec. The parameters were then changed to generate new results but to also try relate this to the LAGI competition. Further exploration involves sperating each chord and extruding them to form a structure. These chords could act as a piezoelectric energy generators to harvest wind forces.

This tutorial allowed was about using mathematical expressions to achieve a customized voronoi pattern. Further explarotion includes trying to giving this pattern thickness through using extrude component.

W e e k 5 E x p r e s s i o n s

This tutorial again was about using mathematical expressions to achieve a customized pattern effect on a surface. A random reduc component and cull pattern was used to generate a denser effect. This could be useful for a design propsal for the 2014 LAGI as a customized pattern can be projected onto a surface.

Field Fundamentals introduced the representation of fields using vectors. The line and point charage where used to see the varrying displays.

Image Sampling introduced the idea of generating a pattern from an image. This together with could be used to map wind directions and gradients which can influence siting and positioning of our design proposal.

Continuing on from the Field Fundamentals video further exploration of the field components was conducted, looking at how to use the spin force component. This create varrying fields which could possibly be used to map wind flows of the LAGI site.

Using the graphmapper to develop a custom pattern with the size of each cell changing with the radius of each cirle. Weaver bird’s offset mesh component was used to create a frame for the pattern.

After replicating the video tutorilas I went further and applied a wind force to the Voussoir cloud geometry. The direction and amplitude was varied to see the effects and resulted in an understanding of how to use the kangaroo plug-in to simulation material behaviour, and in regards to our design proposal the behaviour of panels can be simulated under wind.
