WEEK 1WEEK 1LOFT

In the fisrt week I tested the 'loft' definition in Grasshopper to see how different curves might generate different forms of loft. I found that the outcomes of lofts can be smooth or can be straight. For future development, smooth result can be used for roofs, and straight result can be applied to panels and walls.

OC TREEOc Tree component turns a surface into platforms. It was described in tutorial videos as a useful tool in game design, but I think it also helps to form platforms in real-world architecture.

VORONOIIt is an interesting tool to divide a surface or solid into polygons. It creates interesting patterns around or among an object.

SMOOTH MESH

GRIDSHELLSPHERE

Through creating the sphere, I practised definitions such as sphere, divide surface, explode tree, shift list, and loft. I developed an initial understanding of data tree, which I think is critical in using Grasshoper to design.

WEEK 3WEEK 3DATA TREE

I tested more possibilities on the knowledge based on data tree. Panel component allowed me to define the formula and generate differentiated patterns.

WEEK 4WEEK 4

SECTIONING

This week I used Banq Restaurant (designed by Office dA) as my case study. In Grasshopper I specifically tested the contour component. I tried different patterns, l eng ths , rad i us , and some other parameters to see the effect on the outcomes.

NTPNTPCASE STUDY:PORTRAIT BUILDINGI did a case study on Portrait Building because I was shock when I first saw the face on the building from very far. A Grasshopper definition for the portrait building on LMS helped me discovered the secret of the stunning effect - image sampling. Through changing the image and width and number of slices, I made several portrai building with other faces. Also I found the colour contrast between the panels and building is important.

WEEK 5WEEK 5EVALUATE FIELD

Po p i n g a n v a l u a t e f i e l d component after dividing surface gives me a l ist of points. Through remapping the radius of circles based on the points, I evaluated the expression with variables y and z. This gives me an outcome of that the smaller the x, y and z value are, the bigger the circles are. It creates regular shapes on a surface.

WEEK 5WEEK 5IMAGE SAMPLING

Simi lar outcome as above can be achieved by image sampling as well.

This bridge structure was the initial idea of our interim presentation. It's a helix bridge consists of steel strucuture and tensile rope structure.
