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.

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.

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.

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.

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.

as kangaroo mesh surfaces could not be unrolled and fabricated, this method of drawing arcs and manipulating the curvature by moving mid point and interpolating is used instead. This creates a very smooth gradiance of panels according to proximity to curve. It is imperfect, however, as panels tend to fill in negative space when too far from the attractor curve. However, it does create very interesting patterns.
