Generate mesh and smooth mesh

grasshopper is able to offset multiple curves at same time, which is more convenience than doing it in Rhino.

Creating a curved tube, it is same as adding thickness to simple line. It will be helpful to cre-ate structure thickness in future practise.

Project surface to 2D, easy for having simple elevation of a structure.

Creating section surfaces from a single surfaceLabeling those surface in a grid for later fabri-cation. Grasshopper has a easy method to achieve this process. This is a good sample for labeling and fabrication.

puting geomatries on curves along the surface

Creating Gridshellthis is a process of creating structure form along the curved line, this can be helpful to generate a line structure for fur-ther development.

The yellow panel shows the output data in a list, it is good to use to when there is problem with form shape and structure

Patterning listsCreating different types of pattern on a surface, the surface can be plat.Can the surface be curved? Further development

Problem with cull

Why some are not connected

Creating Voronoi pattern based structure. “soild difference” commend can combine two solid form into one.Different scale can give this structrue dif-ferent meaning.

From case study oneUsing field to create patternsThe pattern can be changed by entering different parameter, it is a good starting point for people to study and generate different kinds of curves.

Random pattern mesh surface.Use a new plug-in “weaverbird”, it is very easy to use as a mesh creatorPutting the random value into the definition, the results are interesting. Maybe use them as type of modern window frame.

Studying “cull pattern” and “dispatch” command

Cull pattern can remove elements from a existing list, it often help people to select the thing that they want from list.

Dispatch command is separate a list into two and how to separate can also be controlled by entering true false pattern command.

Dividing surface into series parts, creating pattern along the surface.Remind me of Michelin.

REVERSE-ENGINEER

The definition i made has the limitation on controlling curve and changing patterns. Some triangular pattern are clash with each other, which is not a successful result. Need to add some command for controlling curve.

After adding the graph mapper to the evaluated curve, all the curves are able to be controlled. Furthermore, there is no clash between pattern.

Want to develop some surface, first think in my head is wavestart to create wave surface, using sine expression.

Limits: wave can only move in one direction, how about creating some wave surface that is capable to move in multiple directions.

Water drop effectOther attempt for creating wave surface. this time I was able to a kind of water wave effect, the expression is based on sine too, but much more complicated. Maybe can collect some curves from those surface and use them as a water wave data.

Urban city experimentAgain using random factor and voronoi to develop some ran-dom urban planning. Why we like random stuff, because it always give us surprise

Low density low rise

Medium density medium rise

High density high rise

Using the similar definition as previousAim to create some random curves and surface

DEVELOPING SPINE

Creating basic spine shape form

ONE

Change each panel’s shape by putting a attracting point

Limits: difficulty due to control the size changing for panels

TWO

Similar result but different approachThis time a graph mapper is added into the definition to give a control of the size changing in each panel

Crazy spiral stairTaking the idea of spiral, can use it to create spiral curves

Spiral structure matrixpotential to develop them into spine structure

SPIRAL SPINE

CURVE MANIPULATION

Use point to change push lines on the Z axis

point on line point pushes line changing push value

push in negative direction

multiple points

point doesn’t need to be on the linethey can be anywhere around the linemagnetic field based logic

experiment 1

experiment 2

Changing parameter for getting different values

Using magnetic field as basic logic

this curve manipulation definition is going to help us creating curve and also space

instead of using point to push linehow about use curve to push curve

FURTHER DEVELOP THE PREVIOUS LOGIC

curve on pathway push the curve up change the size

multiple pathway

change the size

push up alone Z axis

parameter for different usage

experiment 2 experiment 3

experiment 5 creating sculpture form

SITE MODEL fabrcation

Noticing the 3D printer is not suitable for the final de-sign there for using panel tool to creating flat strips.

Curve to surface to panel surface for making site model

Separate cut line and score line

SPINE REFINEMENT

Creating fins along the curveRotating into different direction

Rotation controlCurve

Dividing curve

Rotating divided curves

Creating surface between curves

Rotating divided curves

Cull patternSelecting surface for fins

Dividing into levelsCreating different functions for different levelAdding substructures

Defining curve into different lev-els for different functions

Top: transparent rotatable fins (energy generator)Middle: transparent panelsBottom: solid panels, larger size

Creating substructure for supporting reason

Generally looking of the spine

STRUCTURE AND DESIGN ISSUES FOR NEXT PART

Fins are thin and without pro-tectionFurther develop the fin for top level

Jointing problemHow to connect each core structure?Using a joint (has to be rotatable & able to have 360 degree rotation in order to achieve design intent)

FINS DESIGN AND ADDING PIEZO-CELLS

Material: 2mm White Perspex

scale 1:5

scale 1:10

scale 1:10

DESIGNING JOINT

Due to the difficulty of using grasshopper to design the whole joint, the definition is showing the relation between the core structure and joint

For me many detail part are not able to be make by grasshopper in a short period of time, therefore i used rhino to refine the joint design

using 3mm MDF material to fabri-cate the jointconsidering the thickness and size in the fabrication method.
