TRIGONOMETRIC FUNCTIONS

BOTTOM:SERIES+ MANUAL ALGORITHM (SINE AND COS AND PHI)+ CONSTRUCT POINT+ CULL LIST+ VORONOI 3D+ BOX+ INTERPOLATE CURVE

I initially used sine and cosine functions and

found them to create very symmetrical outcomes so

using a tan equation instead produced a more organic and interesting outcome.

COMBINED TECHNIQUES INCLUDING:‘FIELD FUNDAMENTALS’ + ‘TRANSFORM MENU’

After investigating Field Fundamentals I decided to re-visit the Box-Morph

technique from earlier weeks to see whether I could combine the two.

I found the outcomes to be dynamic but still have a structure nature from the

gridded boxes.

COMBINING TECHNIQUES

COMBINING TECHNIQUES INCLUDING:‘FIELD FUNDAMENTALS’+ ‘TRIANGULATION ALGORITHMS’ + ‘VECTORS’

I’ve found Voronoi 3D to always reduce the expression of certain design intents. In this case, evidence of the Field Strength’s effect

on its surroundings has been lessened because of Voronoi’s cell-creation

spatiality.

DESIGN CRITERIA 37

The overall forms of various ‘levels’ or ‘platforms’ reminds me a lot of today’s

skyscraper designs - a combination of the old (traditionally achievable

horizontal geometries) with the new (fluid, dynamic

vertical forms)

38 DESIGN CRITERIA

EVALUATING FIELDS

POPULATE 2D + DIVIDE+ SPIN FORCE+ POINT CHARGE + MERGE FIELDS + CIRCLE + DIVIDE + FIELD LINES

DESIGN CRITERIA 39

I found this result to be one of the more interesting

Field Line experiments. The gradual increase in line thicknesses due to

the increasing density of Field Lines gave a stronger

sense of contrast to the composition. The idea of fluid accumulation also

reminded me of the flow of water in producing rivers.

IMAGE SAMPLING

I decided to play around with the Spin Force’s strength and decay to refine the overall aesthetic of the towering forms. I felt the ‘right’ sense of rotation provided the model a strong sense of dynamics

and movement, almost as if this was a snapshot of the model before it flew off or collapsed.

COMBINED TECHNIQUES INCLUDING: ‘GRAPH MAPPER’ + ‘CULL PATTERNS’+ ‘TRANSFORM MENU’

After many earlier attempts, I managed to finally extrude

and offset curves to solids based on distances between the base objects and an external attractor.

I decided to further experiment with these new abilities by applying it to a hexagonal grid, freeform

surface which was another challenge in itself.

Playing around with the Customer Preview and Colour picker settings

allowed me to emphasise specific design intents. In

this case, I wanted to create a stronger sense between

foreground and background by using a very light grey

and a very dark grey respectively.

DESIGN CRITERIA 47

Through creating my own Cull Pattern, I produced a tower with interesting

hierarchal nature. It reminded me of some of OMA’s works (although they did not necessarily

use parametric modelling) and their ‘hyper-rational’

approaches to ‘form follows program’.

I found the most challenging section of the script was

figuring out how to manage the data to offset the points

before interpolating them into smooth curves.

DESIGN CRITERIA 51

I really like the clean joints between the circular-packed

panels. It gives me the impression of a levitating

structure.

KANGAROOEXPERIMENTING WITH OTHER CASE STUDIES - REVERSE ENGINEERING

Learning about the basic Kangaroo force and anchor

point components from LAVA’s Green Void allowed me to apply information directly into this similar case study.
