1. Create 3 random points using number slider and digit scroller 2. Feed the points to Interpolate command to form a curve3. The same procedure for the other curve4. Use the Extend Line command to extend one of the curve at the ends5. Generate surface using Loft command and achieve different results by changing the param-eters

WEEK 1 1. VASE

4

The strategy is to create different circles at different positions in z axix and loft them to create the vol-umn, the form is changed through control points.

1. Generate a series of number from 0 to 2 pi 2. Input these numbers to points and create a y = sin(x) function using the graph mapper3. Duplicate the process and create another sin curve 4. Loft the two curves to form a surface5. Offset the surface, however it does not have a solid option in GH5. Explode the edges and loft again to obtain a solid object

1. Define random points 2. Form closed curves using those points 3. Create surface of the closed loop4. loft to create the volumn

1. Construct four points to create a curve2. At the end of the curve, form a circle with its centre located at the end point3. Sweep the circle along the rail line

WEEK 2Pavilion

Weaverbird Method

The pavilion is created by catenary between two closed curve. The height of the curve is determined by an influencing factor point that pass through the pavilion. In practise, the influencing factor could be the direction of sun, the view, or the circulation pattern. From the studio, I applied the weaverbird texture to the pavilion.

14

The contouring method divide the pavilion geometry vertically into equal pieces to provide an interesting visual effect. In a real project, the contouring method generates interesting shadow pattern from the sunlight and makes the object more interactive.

WEEK 2Pavilion

16

Inspired by the online tutorial. The driftwood method divides the pavilion into vertical compo-nents that makes the manufacturing process easier by digital fabrication. It gives the pavilion a fluid look that creates interesting visual effect with timber.

WEEK 2Data Tree

20

I created a random curve among the grid system to see how the cull pattern works. By changing the 4 boolean toggle I have obtained different density of curves that connect points from the grid to the points on the curve. The cull pattern ignores the row of points on the grid that is set to false.

21

WEEK 3Cull Pattern 1

22

By adding the flatten tree command to the grid system, the data has become a single branch. Interestingly, the pattern has changed as well. The row of points becomes diagonal in the cull pattern. And all curves seem to join at the end of the random curve i created.

23

WEEK 3Cull Pattern 2

24

The voronoi pattern is formed by hexagons with each face connecting to another hexagon. The structure is very efficient as it was used in the Water Cube in China. It cannot be achieved with-out the cull pattern command to ignore the alternating diagonal string of points.

25

WEEK 3Voronoi

26

Gathering a pattern such as pedestrian movement, noise, heat can be very useful in the analyz-ing stage in design. In this example, the density of brightness is presented by the size of the di-ameter of a circle; The brighter the larger diameter. Cull pattern can be used to delete unwanted information that exceeds the limit.

WEEK 3Image Sampler

28

To apply a grid pattern on a surface, it needs to be reparametized in order to fit into the new defined space. By using this method, any pattern can be applied to buildings easily.
