Introduction W1- Vase Design W2- Pavilion W3- Geometry Patterns
Vase 1 - I Began with a basic design in grasshopper by applying 4 circles and extruding them to diffferent heights then applying the loft command.
Vase 2- For this strategy i used a polygon command with 6 sides (Hexagon)and
inserted a stack effect then applied a divider that created a sequence of the same shape.
Vase 3-
For this strategy I used 2 cirles and connected them wiht the use of a shift list command that created a diagonal connection between the vertically distanced circles.
Vase 4-
For this strategy i used a variation of curves and slider options altering
the radius and height of the vase.
Vase 5-
For the final strategy i used a variety of ploygon shapes ranging from 3 sided to a 7 sided ploygon through the manipulation of the number slider to obtain differetn stacks and radius sizes.
Week 2 Pavilion
This week’s task was to create a 20*20m pavilion in Merri Creek, that responds to changing chracteristics. This was obtained by using Rhino and Grasshopper through the attractor field with the change being of natural causes (e.g. sound). Once the first pavilion was made three material applications were added in grasshoper, by the use of a weaverbird plugin. As a result 3 different finishes were observed as seen below.

Side Task -Data Trees All 3 types
This week’s side task was to make a data tree and explore the possible variations possible through the use of a short list, long list, and cross reference. The diagrams above show a mixture of short, long and cross referenced lists.
Short List
These diagrams show the implimentation of the short list command on the data tree.
Long List
These diagrams show the implimentation of the long list command on the data tree.
Cross Reference
These diagrams show the implimentation of the cross referencecommand on the data tree.
Week 3 Geometric Patterning
This Week’s Task: 1- Cull / list item from a grid / connect points with lines - cull / list 2- Item from a grid / connect points with lines (flatten a grid’s data structure / use “flattern tree”) 3- Image sampling to modulate circles / 4- Curves on a grid - voronoi / cull / list item
This task enabled me to explore the different variations and patterns available in parametric modelling programs and the ability to integrate this into my design is exciting. A few of the following strategies are shown in one or more scripting techniques which may create different physical shapes.
Pattern 1This pattern was made out by creating a simple connection between 2 curves and creating a cross reference list link both of them together in order to make different patterns.
Pattern 1(Different Strategy)- With this pat-
tern I used a different strategy and scripting to come up with 2 grid layers and cross referenced to create the points on the grid to create the following pattern.
Pattern 2- This strategy involved the use of a different non
square grid, with multiple geometries applied and with the use of a flatten tree to trim down extruding surfaces.
Pattern 3- This strategy used a digital picture (Black and
White) to create a pattern in a grid by the use of referencing 0 to black colour and 1 to white colour, which as a result produces different sized circles.
Pattern 3 (Different Strategy)- This strategy
made use of the same image based pattern but used a data tree to manage the large number of data and also numbered the grid and coloured points of it.
Pattern 4- This pattern was created by using a 2D voronoi
component , a Boolean command was used to create a scattered number of a certain shape by the use of true and false data manipulation.
Pattern 5 (Attractor Strategy)- This was an
extra pattern that I wanted to explore and see what kind of effect it had on the overall shape. The strategy made use attractors, like the pavilion from the previous task consequently a point chosen at random created a dispersion in the number and size of circles around that point.
Week 4 Mathematical Functions
This weeks task was to: 1&2) Create 2 mathematical scripts, one using trig functions with any lofted surface. One with an ‘If ’ function and compare the results. 3&4) Create a pattern using mathematical functions replicating natural patterns. One using any math function, and the second using an ‘If ’ function
Task 1- Lofted surface using trigonometric functions.
Shape produced through use of Sin and Cosine functions producing a spiral like curve and rounded edges.
Task 2- Lofted surface using the trigonometric functions and the additon of an ‘If ’ function. Shape produced through use of Sin and Cosine functions producing a spiral like curve and rounded edges. the addition of the ‘If ’ function added a sharper look to the lofted surface, with less rounded edges.
Task 3 (extra exploration) Experimentation with extra patterns and trying to replicate naturally occuring patterns. Dna Strand modeled in Grasshopper with a mathematical function, by usinf tan and Tan and Sin functions to resemble the twisting nature of a dna structure. Sun flower petal pattern re modeled in grasshopper by the use of a sin and cosine function .
Task 3 (Final pattern)- This pattern used the exploration from the Sun flower pattern and the DNA strand and focused on a natural ornament like pattern such as the sun flower pattern that is found in religous buildings such as mosques and churches as seen below. This pattern mixed all 3 ideas and inspirations into this mixture, I would like toe explore this kind of reccuring tesselations for my design.
Task 4- This is the same pattern but with the implimentation of an ‘If ’ function, which produced a totally different result
