CONCEPTUALISATION 3

a.6 appendix: algorithmic sketches

week 1: triangulation algorithms

I transferred an extruded curve from Rhino into Grasshopper and used populate geometry command to create random points on this surface. Then the 3D voronoi tool was then used to break up this geometry into smaller pieces. Instead of deleteing some fragments as shown in the tutorial, I decided to keep them and shift them out. They can be used as seats or landscaping elements that relates to the overall structure. What is left behind is a voronoi facade with openings and a curved wall which can be used as structural support.

week 2: curve menu

This is an adaptation of the arc tutorial whereby points along two curves are joint to form an arc. Instead of using an arc, I experimented with Bezier Span tool which allows me to create an S-shaped spline. I think this can be a canopy for people to travel underneath and solar panels can be arranged on the top of the surface as the grid is facing one direction. It would be an interesting experience for people to be able to view the solar panels from below and I can explore with various paneling effects on the roof.

week 2: curve divisions and cross reference

The following two algorithmic sketches show my explorations with the cross refereence tool. Cross reference allows us to connect one point from parameter A to all the points in parameter B. I am intrigued by how this tool allows more complex patterns to be formed based on simple rules. I really like the resultant pattern formed by the overlapping lines.

The points of intersections between the lines can also be determined using the curve intersect tool to create a unique grid of points. In virtual environments, I made my analytical drawing by using a protractor to create a grid and then joining up lines to form a pattern between the points. Looking back, I think this process is rather time-consuming, less accurate and difficult to modify. Grids had to be redrawn to achieve multiple iterations and development. Through the use of computation, parameters like number of division points, lengths of lines/arcs can be manipulated easily to change the pattern. Hence, moving designing towards relationships between parameters rather than a static creation.

These line works can also be useful in creating tensile structures whereby forces can be calculated and loads be distributed evenly to various points of the support.

CONCEPTUALISATION 5

week 3: gridshell

This last algorithmic sketch is based on the gridshell tutorial whereby three circles are divided into points and arcs are being formed by joining a point in each circle together. I think this technique is suitable for weaving elements together. In doing so, one must understand the bending properties of materials well and consider the joinings between pieces.

week 4: field fundamentals

For this algorithmic sketch, I placed two fields within each other and tested out how the direction of the resultant vectors would be affected. I then related the magnitudes of the resultant forces at each point to the radius of circles to achieve the resultant pattern in below.

week 5: graph controllers

These sketches explore the use of equations and a culling pattern to generate a series of point locations. The delaunay edges and voronoi produce interesting effects and forms.

week 5: evaluating fields

The following sketch is about placing point charges on a circle and controlling how these lines will bend using graph mappers. This stimulates the effects of trees swaying in the wind. This is a useful tool in creating multiple iterations of the same unit over a curve/grid of points. The movement of the curves can be along the x, y or z axis to achieve more dynamic variations.

week 7: fractal patterns

This week’s video explore the use of recursive functions to generate repeated branching, I merged the curves with kinked polylines to create dynamic and random movement.

Explorations of the voussoir clouds algorithms using a negative scaling in the z-axis to stimulating forces pulling upwards.
