TRIGONOMETRIC FUNCTIONS
TOP: SINE + POINT FROM X, Y, Z 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. 28 DESIGN CRITERIA

COMBINING TECHNIQUES
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.

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.

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)

EVALUATING FIELDS
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.

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.

COMBINING TECHNIQUES
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.

COMBINING TECHNIQUES
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.

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.

I really like the clean joints between the circular-packed panels. It gives me the impression of a levitating structure.

KANGAROO EXPERIMENTING 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. 52 DESIGN CRITERIA
