VASE 01 MESH TRIAGULATION & REDUCING POLYGONS

Turning curved surfaces into triangulated mesh and reducing the polygons can simplify surfaces to create a simple, geometric formation. Although this form does not follow the exact panels of the reference vase, the random index selection tool allows me to generate an array of outputs, all in which are different.

VASE 03

POINT TO PROFILE, LOFT & TWIST

cross section profiles were divided into nodes before connected and twisted together to form a organic shape. Depending on where the cross sections are placed, (as well as scale and other variables), the formation of the vase could look immensly different.

VASE 04 DIVIDE & SWEEP 2

Similar to lofting, curves were divided and sweep 2 was used to create this form. The inputs were modified and iterated to more accurately mimic this shape.

METHOD 01 BOUNDING BOX

The bounding box method allows the initial geometry to stretch along the surface. Hence, each surface may have controlled variables (such as rotation angle and shape) but scale and stretch may differ.

METHOD 02 PLANE AND ORIENT

geometry must be aligned to the planes that were divided from a surface. Hence, only the base point/line of the geometry will follow the surface. this allows geometry to fit tightly to the surface, but causes gaps to incur between each module. In order to imitate the overlapping texture of fish scale, the surface had to be copied and moved.

PANELLING TOOLS

1ST & 2ND GRID i personally prefer the panelling tools method most as it has highest flexibility, retaining cohesive patternation (such as orientation and plane) while gradiating in different properties (such as length, and rotation). However, while this method enables to transform from one shape to another (even if it is a completely different form), a drawback is the need to copy and alternate each component as separate solids before morphing them on a pointed surface.

AA DRIFTWOOD PAVILIOIN

Following exlab's tutorial, i tried to replicate the AA driftwood pavilion by intersecting offsetted surfaces with original brep, and trimming them off by culling inters that were beyong the input geometry. This produces curved contours.

The graph mapper creates a wide range of inputs that patternate in dynamic ways. Iterating the graph typology, the graph frequency and graph bounds alone create individualized geometries that could be static or potentially kinetic or contain movement.

ATTRACTOR POINTS AND FIELD LINES

SHOWING MERGED FIELD LINES AND CHARGE OF ATTRACTOR POINTS

As attractor points mimic magnetic fields which allow attraction or repelling forces, it enables organic patternation on surfaces. As attractor points could also perform among 3D spaces, there is a high potential to generate new spatial experiences within a volume.

Imitating the works of Aranda Larsch, repeated geometries (in this case, tetrahedras) were created and oriented in a way that becomes a repeated, almost evolving creature which twists and warps. Through patterning and repeated steps, interesting geometries begin to form, resulting in a magnitude of interesting compositions.

CHANGING HOW MUCH THE 'BLOB' MERGES TOGETHER BY MODIFYING THRESHOLD VALUE

As I explored the notion of metaballs for Case study 2.0, I looked at various ways which would most efficiently and accurately represent my case study. In addition, I strived to create and iterate scripts in a way that would allow for highly customized parameters. This is to provide enough scope for experimentation in section B4.

WHAT ARE THE POTENTIALS? There are two main advantages of stop at the xy plane, enabling it to it could be flatly aligned to the ceili Inspiration cloud by Tara Donovan. S be iterated, the vector could also b individual point in any axis, x y or customizable.

CONCEPTUALISATION


Unlike the previous method, this approach finds curves along 2 axis of the metaballs before merging them together into forming a gridded geometry. WHAT ARE THE POTENTIALS? As the final geometry is composed of two metaball components, the simple script is less heavy yet produces similar output as the other two methods. Location and threshold of each 'blob' could also be customized, where location is altered in rhino and threshold in grasshopper. WHY WAS THE METHOD ABANDONED? similarly to the previous script, it provides effective curves and points, but fails to create a surface. Furthermore, it does not cut flat on any side. This, however, could be solved by strategically modifying the bounding box.

i examined the very fundemental planarization of the meshed metaballs for part C development, striving to achieve gradience within the fabrication process. Hence, i Decided to investigate the iteraction of scale and geometry to see which would be more suitable for our design devleopment.

Using very basic unary forces in Kangaroo, I attempted to mimick the flow of waste in our specific selected site. As water flows from North west to South East, the waste drifts under the bridge. However, at the current stage, the simulation is merely in plan, without considering the river bends and high/ low water levels. Hence, this is something i seek to investigate in the next stage. This simulation allows us to more realistically see how our design will react to real world forces on site.
