LOFTING IN RHINO COMPARED TO GRASSHOPPER

Lofting between curves on Rhino created the same outcome as lofting curves in Grasshopper, however when lofting in Rhino the surface created is not changed if you edit the original curves. In grasshopper this function was activated and edited the original curves allowed for the surface to then reshape according to the new curves. This creates a much easier work flow.

Creating geometric shapes using grasshopper and transferring it back to Rhino was a simple task once understood. This form of Geometric shapes can be used in built form, and already one can see the relationship between this modeling and built examples.

VECTORS AND MESHING IN GRASSHOPPER

A vector defines direction and magnitude, and is usually described in grasshopper using 3 coordinates.

Vectors can be used for scaling/ratios and/or rotations along with other movements. Points are used to specify the position of something and Planes are used to describe orientation.

This exercise demonstrated how to reference two vectors into grasshopper to then find the average vector motion, grasshopper does this by using basic trigonomic functions. (Displayed above). Displayed below is the same function however applying the functions manually rather than using the individual grasshopper tool to work it all out.

Lists display what is contained in the unit. (As above)

CURVES IN GRASSHOPPER

This function uses two existing curves and from there creates points on the curved surfaces (can edit the number of points on these) and then create arcs from these points.

Adding onto the previous function, this allows you to add points onto the arcs, this is essentially dividing up the arc.

Function creating a grid like structure onto the arcs.

GEODESIC CURVE IN GRASSHOPPER

From the curve exercise where arcs were created you could from there create a geodesic curve which give the arcs strange angles to work from creating interesting forms.

Lofting those geodesic curves then creates an interesting loft.

DRIFTWOOD EXERCISE

Exercise to create a surface to be constructed of driftwood.

Using a basic geometric form in rhino, you reference that into grasshopper and then create a closed curve on the inside of the shape, offsetting and extruding that curve and cutting off edges creates the form on the right.

ALGORITHMIC TASK - WEEK 2 6

EMILY LUCCHESI _ 585234 SEMESTER 1 / 2014

CREATING A GRID SHELL

From referencing a curve onto grasshopper you can begin to create shells and grids that define the shape.

In these examples the curves have been referenced in, divided into individual points along the surface then exploded to allow an arc to go through those points. In order to loft that surface an extra calculation needs to be made (as in grasshopper diagram on above right).

After the loft has been created, you can create geodesic curves onto the surface, however due to the nature of the curve the geodesic curve will only work with certain inputs; start and ends points. By moving and adjusting the position of the points that is inputted to the geodesic curve it creates a different curve each time based on the input information.

PATTERNING LISTS

Using a basic surface you can create interesting patterns through grasshopper. A ‘surface divider’ allows you to divide the surface into multiple points, these can be adjusted using the slider command. By then flattening these and using a voronoi component you can begin to create your own patterns. Using the extrude button you can define the boundary. However this function would not work on the model I was working off (unknown reason to date).

By using the ‘Cull Pattern’ command you can adjust the pattern of points in which the voronoi pattern follows. The cull pattern then allows you to attach a list to it defining your own individual pattern by either deleting or including the points to use.

In order to create a more random based pattern, you can use a jitter component which then scrambles the list of points into a random assortment of numbers.

ALGORITHMIC TASK - WEEK 3 8

EXPERIMENTING WITH PATTERNING LISTS I discovered that experimenting with the existing patterning lists was a simple task, however by changing the original surface shape it could create even more interesting shapes and patterns onto the surface. This however also limits the amount of variation between patterns.

Below are three examples of my experimentation with a surface created from curves drawn in rhino. This was done so to see if the patterning was able to form on surfaces other than just a square or rectangle.

Using this theory the patterning should be able to function on any surface on a three-dimensional form.

EXPERIMENTING WITH PATTERNING LISTS

Beginning with a basic loft between curves and then referencing into grasshopper I was able to apply the patterning operations onto the surface.

In addition to this I created my own personalized shape and then used that shape to form the pattern onto the surface.

EMILY LUCCHESI _ 585234 SEMESTER 1 / 2014

Parametric modeling is essentially using the computer to design objects by modeling their components with real-world behaviors and attributes. In using grasshopper and Rhinoceros it was much easier to understand the algorithmic and parametric modeling concepts that the readings and further research were discussing.

I found that not only was I able to generate forms by placing the components correctly but also the generation of form when placing something incorrectly.

These mistakes eventually turned to designs (tweaking it so the model would work).

Throughout my explorations in parametric modeling I noticed that most of the form work I had been creating in the software was similar to some projects I had seen in real life and precedents that I had researched.

The limitations in such programs seem endless.

However with extraordinary designs using such programs comes great knowledge in the way in which the program is used. These were my major limitations.

I was able to create forms and designs however I was limited to what I knew, for example below I created an archway with a circular pattern on it. This could have been created much more elaborately however as my knowledge of the program is limited, the design too, is limited.

EMILY LUCCHESI _ 585234 SEMESTER 1 / 2014

The expressions fundamentals indicate the level of strength and forms coming from the vortex’s This can be useful as the strength of projection of the vortex can be mapped out in different ways. These ways create beautiful forms and visual representations.

FIELD FUNDAMENTALS - EXPRESSIONS These expression, complex as they may seem, can be useful in creating a very curved geometry, one that you are able to control completely.

Simply drawing in rhino will take a long time to create such a form however grasshopper has created a definition that simplifies the process down, making the ability to create controlled curves a much easier function.

THE KLUPA 1000 CM BENCH DESIGN - REVERSE ENGINEER

The base shape of either end of the bench were drawn into rhino, lofted and then referenced as a surface into grasshopper.

The surface was divided up into points and then lines were fit through it.

However the lines would run the opposite way of which the slats ran in the real bench design.

This method proved to be a dead end, as due to our lack of skill we were unable to create lines that ran the opposite direction, to mimic the form of the bench.

REVERSE ENGINEERING 30

EMILY LUCCHESI _ 585234 SEMESTER 1 / 2014

We began this definition by creating two points, moving them along the z-axis and creating a line between the two points. Once this was established we created two polygon forms using the points we created to define their position.

Using a twist function we were able to twist one of the polygon shapes around.

From this twisted form we created a loft to form the boundary of lines.

After lofting the form, we then created divided the points along the line we created before using a number slider to determine the difference between points, referencing this onto the XY plane we then set it to the bounding surface and were able to create lines running across the form.

TREE STATISTICS AND VISUALISATION Text tag creates a list of numeric value into rhino to navigate the points and their location.

Placing a simplify tree structure component before grafting gets rid of the two numeric values of 0,0. Only have information that is specific to each branch.

TREE MENU

Referencing a surface into grasshopper and then dividing the surface up into points, to then panel those points in a pattern to allow for polylines to connect in a certain way.

B placing a surface boundary to the polylines a surface is created forming interesting patterns.

The component ‘shift paths’ allows you to find the average of points on each individual surface of a multiple selection whereas with this component the overall average of all surface points would be found instead.

Changing the panel pattern changes the connection between points on the surface therefore creating a different planar surface

PATH MAPPER

Path mapper component is extremely similar to grafting, where the list that comes out displays one component rather that all of them individually.

This function within the path mapper simply offsets all components by 1.

This function flattens the data.

Adding different functions into the path mapper allows for different pattern along the three-dimensional points. (rhino image on left).

FURTHER DEVELOPING DESIGN 56

EMILY LUCCHESI _ 585234 SEMESTER 1 / 2014

As combining the two definitions led me to a dead end (due to limited time to learn more of the program) I have started a new definition that combines the two main features of these definitions but relating it more to the site itself.

An attempt to also incorporate the Biothing pavilion will be made. In doing the the design should flow with the movement of water vortex’s and be representational of this. create a set of curves in rhino to then reference into grasshopper to then divide and place points charge on

At each point charge put a spin charge in place (representative of how water would avoid an obstacle) Place a field in between spin charges to represent form.

Extrusion of form on z axis, leaning towards y axis slightly.

This creates a maze-like form that could be used as a design for the site.

It represents the way in which the water would move through the vortex and therefore it also influences the way people move through the site.

Materiality of this could also impact what the design can look like.

FURTHERING DESIGN - PIPING

In order to create these pipes, I first moved each line in the z direction to create three layers as to mimic a wall. From this I then baked those lines into rhino and referenced them back into grasshopper as curves, then added the piping component.

If I didn’t not bake the lines back into rhino, grasshopper would not function (perhaps the capacity of my computer) and it would crash, so therefore by baking and referencing as curves separate from a definition grasshopper was able to convert the lines to pipes.

ALGORITHMIC SKETCHBOOK APPENDIX COMPUTATIONAL DESIGN

due to the fact that I am still learning how to use grasshopper for rhino. This limitation to my knowledge of the program (even Computational design can be taught. One of the brilliant though learning is undergoing at the moment) limits my ability things about this form of design. However in teaching one to to design as effectively as I would like to. design using computation there are limitations like their previous knowledge of such programs or ideas of design. In understanding I however am able to understand from my learnings that parametric design further each week i have come to realise computational design provides limitless amounts of ways in that the ideas that I have are no so easily expressed through which you can achieve desirable effects, with the assistance of algorithmic design. In order to design efficiently one has to not plug-ins such as kangaroo physics and python scripting (there have a preconceived idea of what the design may specifically are many more that I have not yet discovered). These plug-in look like as such as outcome may not be achievable. components allow the program to achieve new boundaries This inability to create what it is that I had in mind may also be and explore the design/algorithm further.

PARTICLE TRAJECTORIES AND LOOPS WITH ANEMONE: ROBERT STUART-SMITH DESIGN - HELSINKI PUBLIC LIBRARY

This begins to map out the direction in which something would flow off the surface, such as water. The beginning of a loop system.

The Anemone loop system allows you to see how the points would flow off the surface as water may flow off it. This also allows you to track the movement of the points as well.

Inserting spin charges allows for the curvature of the movement of pints along the surface. This creates a much mor interesting pattern, and by simply changing the radius and decay of the spin charges different effects can be created.

ALTERING FORM Mapping out the way in which people would move around the site.

From this we would then create arches as to lead them through it.

CREATING THE ARCHES - DEFINITION ABOVE RESULT BOTTOM LEFT. These arcs create an interesting form. Maybe some height manipulation to relate to the amount of wind capture along the site. The arcs should become higher when closer in land as the wind would be blocked by surrounding buildings. and shorter when closer to the ocean.

Creating curved surface to pull curves to, this cruved surface represents the desired height difference

MAPPING TO SURFACE - DEFINITION ABOVE RESULT BOTTOM LEFT. By pulling the curves to the surface above and then using those pulled curves to create the arcs it shows a different form, a more interesting to the one if the arcs were all of the same size.

STRUCTURAL ANALYSIS WITH GALAPAGOS BOLLINGER AND GROHMANN - SKYLINK

Using real-life constrcution elements and measurements to create the basis of a truss in rhino.

The FE solver compnent will tell us what the deflection is for the system in place based on the weights and material information we inputted preivously. The loads that we have and the self weight.

Creating meshes around the surfaces

smoothing out the surfaces by inputting sliders to create this smooth effect. It changes how relaxed this is by changing the amount of relaxation points - but the vertices must be welded together in order to create this relaxation

ISOSURFACING AND MINIMISING WITH MILLIPEDE: MARK FORNES - UNDER TENSION

works in a similar way as the component metaball however will treat the mesh as a series of points rather than a flat surface.

For each vertice the distance to the influence point is found (influence point being the points placed manually in Rhino) To inverse relationshipt of distcane you divide with one so that the inverse is created.

SUN-RESPONSIVE PATTERNS

The test point vectors are the normals of each point and therefore we can use them for the number component so we can orient them.

In order to create circle sizes that correlate with the radiation output they must first be normalised.

To find the normal a mathemoatical calulation needs to be done.

By culling the pattern and setting a minimm value you are able to show a certain number of circles that reach that value

Dividing the mass addition and length will create a point to be the points attractor position. Using hexagonal panels in the lunchbox addon for grasshopper we are then able to use these attractor points to scale the hexagons

To establish a link between the cells and the radiation analysis a closest point component is used and then the lines are joined up to create this link.

Using a panel we are able to view the list coming out from the CP component and from this we are then able to use these indexes to select the specific radiation result we want to use to scale each cell

FINALISING THE SKETCHBOOK 88

EMILY LUCCHESI _ 585234 SEMESTER 1 / 2014

CONCLUSION

In working through the algorithmic sketchbook I have noted that there are many ways to do one thing and that in order to be able to create brilliant designs inspired and created by algorithmic modeling the user would have to have had extensive, or intensive, reseach and practice on such programs. However these progrmas are able to simluate so many ‘real life’ occurances that it is a waste not to utilize such software.

Algorithmic modeling is able to expand the ideas of the designer in ways he or she would not have imagined.

There are components and addons and plugins that are able to do virtually anything you think is possble.

By simply ‘playing around’ with what different compnenets do one i also able to gain an understanding of how such programs work.

In my learning of Grasshopper, my understanding of how scriting, and algorithmic softwares has developped, I still have a long way to go to iimprove my technical skills however there are plenty of useful resources to assist anyone in learning these programs.
