WEEK 1SEA SPONGES

SEA SPONGESSea sponge 3

This was the first experimental task using grasshopper. I had to try and create sea sponges using various components such as loft and pipe. This was a fairly difficult task for me because grasshopper is very new to me.

My last sea sponge was the most dif-ficult and interesting one. By deconstructing the brep twice, I was able to have all the planes in various directions to create the randomised appearance.

WEEK 2TRANSFORM MENU

NURBS:Non-Uniform Rational B-SplinesGrasshopper primarily uses NURBS geometry that helps mathematically defines it. It en-ables you to get information on each point or part of the geometry. BURBS can also be used to reference a curve.

POINT:The points can be referenced on the X, Y or Z plane. It is a coordination system that simply specifies the location of something through coordinates such as (0,0,0).

VECTOR:It is described using three coordinates, specifiying direction direction and magnitude. A tangent touches the curve once its on the curve, whereas a normal is perpendicular to a curve.

PLANE:It is used to describe the orientation, Planes have a position in space and helps you know the direction.

LIST:List of data tell us its coordinates.

DATA TREE:Displays the many lists of data, where there are branches that is the the data list. Some paths can be empty and data matching is when you start connecting objects from multiple lists.

TRANSFORMATIONSUsing curves to create its form like the wing image below. I then deconstructed the surface to create points which I could controll. I used the triangular shape to tesselate throughout the surface in which I culd later adjust the size and overlapping of the triangles.

I also used an attractor point that flattened the vertically straight triangles. I moved the attractor point to various positions till i got the desired model.

WEEK 3GRIDSHELL & CULL

Beijing National Stadium, built 2007

WEEK 4FIELD FUNDAMENTALS

Creating a void with arcs. Further experi-mentation can be done by changing the height of the arcs.

Attractor points can have a positive or negative effect on the radius of the circles. The closer the point was, the bigger the circle became, and the opposite reaction would occur too.

EVALUATING FIELDSWith fractal patterning, it was easy to manipulate and change the shape of it becasue it was simply producing ones with different sides. They looked different at various angles and in some situations it was just deleting the unwanted sections.

WEEK 5EVALUATING FIELDS

Here I was able to play with multiple things. Such as the radius of the circle and the number of points. This would affect the density of the circles. The more points meant the more dense it became.

EVALUATING FIELDS

GRAPH CONTROLLERS

Used the cull pattern and shift list to efficiently produce patterns.

IMAGE SAMPLING

HITOSHI ABE

Firstly I made the form and cut out shapes through the chair like form. i then unrolled it and placed the circles on the surface. Manipulating the circles, I was able to allow the circles to come closer or further apart from each other.
