THIS WEEK WAS ABOUT GETTING TO KNOW THE GRASSHOPPER INTERFACE.

SIMILAR TO THE RHINO COMMANDS , GRASSHOPPER ALLOWS THE EASE OF LOFTING HOWEVER IT HAS A CONSTANT HISTORY OF THE FORM AND CURVES SO MOVEMENT OF A LOFT IS SO MUCH SIMPLER.

AS I STATRTED TO EXPLORE THE PROGRAM I FOUND MANY WAYS TO REPRESENT A SHAPE AND FORM INCLUDING THE ABIL ITY TO PAINT THE SURFACE IN A MESH

I THEN EXPLORED THE PROCESS OF CREATING A FORM USING THE DALANAY EDGES AND 3D VECTOR TO CREATE A 2D TRANGULATION PATTERN THAT CAN BE USED FOR TERRAIN

I BELEIVE WHEN UNFOLDING A MODEL CREATED IN GRASSHOPPER THIS IS ONE OF THE MOST VALUBLE COMMANDS THAT I FOUND THROUGH THE ENTIRE WEEK. IT TURNS A VERY TEDIOUS PROCESS INTO SOMETHING SO EASY AND EFFICIENT.

LOOKING BACK AT A SUBJECT SUCH AS VIRTUAL ENVIRONMENTS, I COULD ONLY WISH I KNEW OF THESE TOOLS TO ASSIST ME IN THE PROCESS.

BEGUN TO LOFT A SURFACE CREATED THAT ALLOWS THE FORM TO BE BUILT MUCH MORE EFFICIENT AND QUICKLY. COMPOSED OF STRIPS, THIS FORM GOES FROM A COMPLEX FORM TO SOMETHING EASILY PRODUCED AND FABRICATED.

IN TERMS OF MY FUTURE PROJECTS I WOULD USE THIS METHOS IN ORDER TO ALLOW EASY FABRICATION

WAS INDEED BENEFICIAL FOR ME AS I WAS ABLE TO TAKE MY LOFTED SURFACE AND CREATE A RAW FORM TO CONSIDER IN MY PROJECT. I BELEIVE THAT THIS LOFTED EXPIRAMENTAL SURFACE CAN BE MANIPULATED IN ORDER TO BE USED AS A SOLAR POWERED SURFACE WITH ASTHETIC APPEAL

I HOPE TO FURTHER CREATE COMPLEX FORMS USING THE SKILLS I HAVE EXPLORED THIS WEEK

WORKING ON THE SURFACES, IT BECAME EASIER AND EASIER TO CREATE VARIOUS PATTERNS USING THE BASE GEOMETRY AND SHIFTING, CHANGING AND CREATING NEW SHAPES FOR THE SKIN OF THE SURFACE.

THE IDEA OF A REFERENCE BASE GEOMETRY IS SOMETHING THAT CAN BE EXTREAMLY USEFUL WITHIN THE LAGI PROJECT AS IT WILL CREATE EASE FOR GENERATING SPECIF IC PATTERNS AND FORMS.

This grasshopper def in i t ion uses a base curve , ex t rudes th is curve and creates a voronoi pat tern on the sur face through us ing the sca le c o m p o n e n t s . Many o f these forms were g e n e r a t e d through os ing d i f fe rent base curves .



fol lowing the prev ious def in i t ion , we went on to exp lore fur ther us ing the idea o f t ree d iagraming. Our next a im was to create var ied ex t rus ion lengths by us ing the l i s t components . Th is was an in t res ing process howver the outcome was not as in t ru ig ing as we hoped i t would have been.

Th is is someth ing we may cons ider fur ther exp lor ing through our def in i t ions .

Fol lowing a b lock my des ign th ink ing , I begun to analyse the a t t ractor po in t concept . A l though i t seemed a very complex process , i ga ined a deeper unders tanding in to the way in which i had to create a po int that can pul l out the form to any des ignated point . However , i encountered another problem when i was unable to create a second at t ractor po in t . Th is can be seen as an issue due to the fact that is is much too hard to create a coherent parametr ic form.

G R A S S H O P P E R D E F I N I T I O N 4Once the prev ious def in i t ions were exp lored and analysed, we found that the form i tse l f was too s ta t ic and a more dynamic and organic shape needed to come in to p lay .

I s tar ted wi th a sur face created a o f fset and d iv ided both the or ig ina l sur face and the o f fset . F rom th is , two sprate l i s ts were created whereby then i t tok the area and created a r ibbed form which i lo f ted wi th the o f fset to create a open base sur face .

Fo l lowing th is , i then added a merge component to merege the o f fset and the or ig ina l d iv ided sur face p lanes to create a so l id lo f ted form.

f ina l ly , i took the two lo f ted sur faces and p lugged them in to the d ispach command to cre te two seperate target l i s ts which i then pat terened randomly to create c losed and open sur faces





Af ter c lose analys is o f the prev ious example , the form was work ing howver the fabr icat ion o f the form was prov ing to be far too d i f icu l t - a lmost imposs ib le .

We then explored our top ic once again and came up wi th a s impl i f ied vers ion o f our f i le that we would l ike to fur ther exp lore in the coming weeks .

I t works by creat ing a t r iangulated sur face- us ing a brep component - that is puncured and can be manipula ted through the j i t te r components to create the openings in var ied areas and sufaces .

In look ing at th is process , I would l ike to bet ter unders tand the process o f HoopSnake . Th is wi l l ass is t in creat ing a fur ther computat ional des ign that is both in t r igu ing and unique in des ign .

1.To create th is gradient decent pat tern on a sur face , a manipula ted lo f t was used as a base .

2 .The inputs and outputs were created us ing the grasshopper too ls and c lus tered to create a s impl i f ied a lgor i thm.

3 .Then the pat tern was created by a l ter ing the u and v va lues o f the d iv ided sur face .

4 .Two var ia t ional forms have been created in order to create a c i rcu lar pat tern ra ther than a l inear one .

These forms are in terest ing in the way o f which they a l low for a f lowing organic form that can be l ikened to a b iomimet ic process or format ion . The c lus tered nature o f these forms a l lows for manipula t ion and var ia t ion in the shapes . I t a lso prov ided a re ference to how I can make a

complex def in i t ion c lus tered and repeated in necessary . Fur thermore , these organic l ines (created by each c lus ter ) could be lo f ted to form one sur face and is an in terest ing process to cons ider for par t C .

In using the Kangaroo plug-in for Grasshopper , I was able to bet ter unders tand how we can a im to make our form adaptable and p lug in in format ion f rom externa l sources in order to create a un ique pro ject that can in teract wi th both the users and the s i te . In address ing the br ie f , Kangaroo could be used

in showing movement and analys is o f seasonal adaptat ion o f the form over a speci f ic t ime f rame. I be l ieve that I have ga ined a wel l - rounded idea o f the program however I am not too sure i f I w i l l be able to u t i l i se these ideas in our form as a computat ional

Exper iment ing wi th t r iangulat ion , I was able to create an a lgor i thm which al lowed for a perforated t h r e e - d i m e n s i o n a l sur face . Th is was a s tar t ing point for fur ther exp lorat ions as wi l l be seen in week e ight where th is a lgor i thm ass is ted in my unders tanding

o f how to create a sur face wi th ho les . Aesthet ica l ly , the form appealed to me however , i t was far too d i f f icu l t to map th is to a lo f ted sur face , hence I needed to fur ther analyse my ideas and def in i t ion .




E X P E R I M E N T I N G I N G R A S S H O P P E R Tower One: The f i rs t tower uses the pr inc ipa ls o f the prev ious t r iangulated a lgor i thm. In th is case , I mapped the sur face o f the or ig ina l three-d imensional form. The problem wi th th is form in terms of the br ie f i s that there are no areas wi th an angle which in turn wi l l p rove to be d i f f icu l t to p lace so lar f i lm on the form to co l lect energy .

Tower Two:The second tower came about in order to create a s t ructura l form but a lso to accommodate for the so lar panels that wi l l be p laced on the form to co l lect opt imum amounts o f energy . In creat ing th is form, the o f fsets o f random t r iangles where taken however a f ter car fu l cons iderat ion , the ho les were not

accurate ly p laced as they were tak ing away f rom the forms s t ructure and a lso creat ing ho les where so lar panels wi l l be p laced. The problem in th is case was that the ho les needed to be s imi lar to tower one but the s t ructure o f tower two.

In conclus ion , these two towers were merged – as you wi l l see in the fo l lowing pages in order to create a coherent su i tab le form to fu l f i l the LAGI br ie f and energy generat ion requi rements .
