Responsive Honeycomb Morphologies [Gh3D]

Continuing with the experimentation and research of honeycomb morphologies and a as example for a Workshop I gave recently I developed a Grasshopper tool for creating a responsive skin system ,using my previous VB script component for creating honeycomb patterns.

designplaygrouds at ESARQ

Yesterday I went to give a presentation at the ESARQ to the students of the master of Biodigital architecture , recently they have been introduced to the world of rhinoscript and grashopper , so they invited my to talk about my work and ideas about scripting and digital fabrication i would like to thank Ernesto Bueno profesor and researcher and Alberto Esteves director of the master for the invitation.

arabic tessellations update

Here are just some preview images of the tessellations I´m developing for the Dubai tower competition

arabic tesselations

Currently working in collaboration with KRFR group of Barcelona, in the developmento of a tower for Dubai for the XI ThyssenKrupp Elevator competition, this are the first experiments for generating an arabic pattern tesselation, one of the intentions is that the tesselation takes into consideration enviormental data in its generation steps , more from this project on the next posts.

tower body study

This is an experiment i did some time ago ,the use of analysis tools for form finding is becoming one of the top priorities in my research work that's why i have been using lately Ecotect which is a very powerful enviormental analysis tool.
In this project i made a simple algorithm based on a simple geometry ( ellipse) in order to generate the volume of a tower building . The form of the building was optimized to reduce the wind pressure loads this was achieved by making some wind pressure analysis on ecotect and orienting the thinner part of the build in the same direction of the highest wind current. Also some incidental radiation analysis were made to know the solar exposure of the building this kind of analysis help a lot in order to develop bio climatic systems.Finally i used rhinoscript to make a exoesquleton skin for the building.

my version of a rib builder

Extracting ribs from complex surfaces is one of the clasic scripts that exists so finally y have decided to do my own version it still has some things to fix and also there is missing the massive unroll function to get all the rib sections separate to send it to CNC but the hard part is already finished i will post some photos of the finished work

surface components

Project related with the implementation of components over surface geometries, scripting processes can help us to design and implement diverse components on complex surfaces in order to make more efficient bodies.
Particularly this project had the objective of the elaboration of an algorithm that takes a host surface to generate components that resemble the skin of a reptile, as a result we can see surfaces with a very interesting texture.This work is able to be manufactured becaouse each component is made out of simple triangular planes.

complex surface structures

Back into rhinoscipting here is a project i have developed for making a buildable structure from complex surface , the script takes an input surface and then it divides it in square sections, then it runs a macro wich makes an "x" form component in each squared sections. some improvements are posible you could add more pipe sections around each section, any way to understand it better here is the code feel free to use it and let me know any comments please.

Scripted Creature

Lately i have beeen working back with RhinoScript and as a prctice excercise i wanted to create a script wich helped me to create a generative sculpture like object.The result of playing around with this idea is this scripted creature. For the creation of this figure i developed a script wich works in a simple way , the user needs to input a set of points , the the script will elaborate a net work beetween those points withe a distance conditional then script will ask the user to select the created lines he wants to use for the creation of the structure , then script will complete the task making a lofted surface.

Here is the script perhaps it can be usfel to perform other tasks if you find one please let me know.

water bottle design

As an academic task we were asked to design a water botlle made by injection molded pocess, for my design i proposed a bottle with fluid forms that would be similar to the ones we find in water in a natural enviorment, to achieve this forms i made a script in rhino that gererates diferent sections and the loft them togheter to generate a column with fluid forms , after that i altered the column using t-splines plug-in for rhino to obtain the final form , with the correct size and the exact volume needed for the project.

The material i proposed for my design is the PLA 700D (poliactide acid) wich is very similar to PET with the difference that PLA comes from corn wich is an abundant resource, this material also uses 50% less enegry to manufacture it compared to other polymers derived from oil . Using this materials not only represents a saving in energy but also a closed life cicle of product because once we use our bottle we can make composte with it and it can be used to make more corn wich will be used to make more bottles.

rhinoscript concept furniture

This are some concept furniture ideas i had using the rhinoscript I previously made the surfaces in these exaples are made by panels of plywood and could be joined togheter with cotton ropes in the same way that the Knitted Chair of Emiliano Godoy.

tessellation script

Here are a few images of RhinoScript i made using some ArchCut plugin methods the script takes a host surface and panelize it in triangular rounded sections.
