WEEK 1 Attractor point + Extrude

STEPS: RECTANGULAR GRID | CIRCLE (SHAPE) | POINT | DISTANCE | MATHEMATICS

VARIATIONS: - RELOCATING POINT - REDEFINING VALUES - REDEFINING RADIUS AND SHAPES - MATHEMATICAL DEVICES

NOTES: Other than parametric volumes, the algorithmic definitions can produce interesting patterns too. The red lines captured from plan view illustrate this and these could potentially be employed into a design scheme as well.

WEEK 2 Multiple attractor points + Loft

STEPS: RECTANGULAR GRID - ATTRACTOR POINTS - DISTANCE - MATHEMATICS - INTERPOLATE CURVE - LOFT

VARIATIONS: RELOCATING POINTS / REDIFINING VALUES / REDIFINING CURVE DEGREE / MATHEMATICAL DEVICES

WEEK 3 Controlling collection

STEPS: CURVE / SERIES / OFFSET | PERPENDICULAR FRAMES | LINE / POINTS / VECTOR | VECTOR ROTATION / AMPLITUDE | DECONSTRUCT / CONSTRUCT / ARC | MERGE / LOFT / GRAFT / SIMPLIFY

VARIATIONS: - REDEFINING VALUES - MATHEMATICAL DEVICES - ATTRACTOR POINTS - ROTATION

NOTES: Patterned forms are easily varied and achieved via this series of algorithms. Desired shapes can be manipulated by relocating points on curves or by introducing attractor points. Overlapping modules could be transformed into interlocking elements and then fabricated into a selfsupporting structure.

WEEK 4 Image sampling

STEPS: GRID / POINT / CIRCLE CNR | IMAGE SAMPLER | SPECIFY DOMAIN / TARGET DOMAIN | REMAP VALUES | POINT / MERGE / POLYLINE | OFFSET / EXTRUDE

VARIATIONS: - IMAGE MANIPULATION - DOMAIN SPECIFICATIONS - INTERPOLATE CURVES - LOFT - GEOMETRY / PATTERNS - ATTRACTOR POINTS

NOTES: Image sampling offers the potential of image manipulation according to the brightness value of the selected file. Not only interesting patterns can be attained, but surfaces can be morphed by introducing a meshing definition. The use of an attractor point can also create unique patternation as well as influence extrusion height, ultimately controlling the overall form of the algorithm.

NTP Kangaroo (Pt. 1)

STEPS: BOX - MESH BOX - WEAVERBIRD EDGES - LENGTH - SPRINGS - KANGAROO - BUTTON / TIMER - MESH

NOTES: After not resetting for awhile, the algorithm takes on a randomised form, greatly contrasting from the symmetry before. It is interesting to note the force morphing the algorithm. This is probably my first true outcome of generative design.

WEEK 5 Kangaroo (Pt. 2)

NOTES: This was an addition to the previous script using the weverbird edges, springs and Kangaroo tool. I added anchor points at the corner of the inital box and also added a gravitational force. The physics tool, Kangaroo, can come in handy in simulating material performance, but first the material properties have to be determined. Nonetheless, Kangaroo presents many opportunities as an interactive design tool. With the catenary designs, I experimented with two distinctively different scripts in creating catenary forms. The first was generated using curves and the catenary tool. Variations were made by dividing the lofted surface and deconstruting the Brep so that alterations could be made at a modular scale. The second one was a play with Kangaroo physics to achieve different projections when different forces or anchor points are introduced. This is particularly useful for our project of a ceiling installation as we can test the material properties and simulate its performance which will inform the form or design to a certain degree.

STEPS: CURVES / DIVIDE | CATENARY / LENGTH | LOFT

VARIATIONS: - REMAPPING CURVES - DIVIDE DOMAIN - ISOTRIM - AVERAGE

STEPS: MESH / MESH EDGES - MERGE - LINE (LENGTH) - SOLVER | DISCONTINUITY | LOAD / ANCHOR POINTS | SOLVER
