ACONCEPTUALISATION
LOFTING & STATE CAPTURE
LOFTING + BAKING THREE CURVES
VISUALISING INTERPOLATION OF LOFTED SURFACES
Blanket-like roofing?
Could be good for transitioning between public and private spaces.
Openings seem inviting.
Overall forms seem organic.

MESH GEOMETRYWELD AND MESH SMOOTH
Adjusting the smoothing level transforms geometric model into organic, more dynamic outcome

CONCEPTUALISATION 11
Increasing interpolated curve density highlights the Moire effect
12 CONCEPTUALISATION
TRANSFORM MENUCONTOUR + LOFT (RIGHT)
Lofting did not seem to match that of the tutorial - this one seems too sharp
and geometric. Maybe adjust loft settings?
CONCEPTUALISATION 13
Applying Dolly Zoom increases sense of depth, helping the viewer feel like they are there in the image
14 CONCEPTUALISATION
SCALING AND DISTORTING COUNTOURS
Extending from 2D distortion, I decided to use a 3D reference geometry and play with its forms.
The initial iteration looks a lot more dynamic whereas
the final iteration looks aggressive probably due to
the sharp edges

DRIFTWOOD SURFACESOFFSET + EXTRUSION + SPLIT SURFACE
Experimented with distorting the reference
curves. At some points, the loft surfaces did not appear?
CONCEPTUALISATION 19
20 CONCEPTUALISATION
DATA TREESCROSS REFERENCE
Tried to use Cross Reference on round, organic curves. The overlapping is very
interesting and there is no overall pattern or repetition.
CONCEPTUALISATION 21
Interesting to see the changes in patterns
of holes and overlaps between the threads
joining the lines of points when I change
the number of points on one line (i.e. left line: 20
points, right line: from 30 to 50 points)
22 CONCEPTUALISATION
CULL PATTERNSLIST + CULL
I thought it would be interesting to use an image with a lot
of gradient definition to cull because culling makes it
monotonous and textures are only created through the
difference in sizes of the circles.
CONCEPTUALISATION 23
GRIDSHELLSDIVIDE + EXPLODE TREE + SHIFT + REBUILD + GEODESIC
Explored different geometric configurations and manually rotates curves to investigate
differences between Grasshoper’s Shift function
24 CONCEPTUALISATION
I really like the depth portrayed in this spiral-
within-spiral form
CONCEPTUALISATION 25
PATTERNING LISTSVORONOI + LIST LENGTH + SERIES + JITTER + ITEM + PARTITION + REGION UNION
Added additional offset curves by scaling the average
discountinuity points of the original pattern. This creates amore fabricatable outcome

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.

COMBINING TECHNIQUES
32 DESIGN CRITERIA
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
34 DESIGN CRITERIA
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
PREVIOUS PAGE:SURFACE+ SURFACE DIVIDE + IMAGE SAMPLER + EXPRESSION+ CIRCLE + GRAFT+ CIRCLE + EXPRESSION+ UNIT Z+ MOVE + GRAFT + LOFT
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.

COMBINING TECHNIQUES
PREVIOUS + CURRENT PAGE:COMBINED TECHNIQUES FROM ‘TRANSFORM MENU’ + ‘CULL PATTERNS’ + GENERAL LEARNING
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’.

COMBINING TECHNIQUESEXPERIMENTING WITH OTHER CASE STUDIES - REVERSE ENGINEERING IBA ARCHITECT’S CANTON TOWER
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.
