Osseous Truss Pavilion

In some of the courses I’ve taught, people asked me how to make the structures of these workshop poster images. In this post I show the osseous truss pavilion that I generated to be the image of the workshop at SIGraDi 2009 that I taught along with Gonçalo Castro Henriques.

It is a system originally developed in Grasshopper 0.60019, based on the Surface Box-Box Morph combination explained in section "11.2 Paneling Tools" of the Grasshopper Primer, by Andrew Payne and Rajaa Issa (p.79-83). The first difference is in the prototype that makes the unit of the truss (or geometric pattern, as is referred in the tutorial). In the beginning it was made directly on Rhino, from NURBS curves of degree 2, closing the three points of the triangle of the diagonal division of a square. For this update, the prototype is generated entirely in Grasshopper, using only the grids of control points.

But the key for this to work as the structure from the image is on the topology of the base surface. The base surface of this pavilion is designed in Rhino, lofting between curves that were previously oriented, point by point, to begin longitudinal, grow to become transversal and end longitudinal again, bending over to make a sort of bridge with two supports. The deformation of these surface isocurves was inspired by the stereographic projections of Cartesian grids.

Launching Parametricismo

The name Parametricism was coined by Patrik Schumacher in: Parametricism as Style - Parametricist Manifesto, originally presented at the Venice Architecture Biennale 2008. The idea is being criticized, among other things, because it’s being questioned whether it is valid to continue classifying architecture in styles or trends. Two years have passed and still we haven’t heard many people use the term.

Probably the word Parametricismo won’t be included in Spanish or Portuguese language dictionaries in the near future as well. So I thought it was a good name for a blog in Portuguese on parametric and generative modeling in Architecture and Design.

Thus, the blog formerly known as Design Paramétrico – UP, —born from a workshop I taught at Universidade Positivo, Curitiba— has reborn as Parametricismo to express a more open but still specific web resource about these technologies and methods, with links, news, workshops and other experiences, published mainly in Portuguese, which is unprecedented so far.

I’m already working on it on Twitter and Facebook, and also waiting to confirm some interesting collaborations coming…

Gonzalo Vélez Jahn, premio Francisco De Venanzi

El 18 de junio, al recientemente galardonado Profesor Gonzalo Vélez Jahn, se le hizo entrega del premio Francisco De Venanzi, importante reconocimiento a la trayectoria en investigación en la Universidad Central de Venezuela en el área de Ciencias, Ingeniería y Arquitectura.

Su hijo Roman Vélez, tuvo la gentileza de compartir su experiencia de asistir al evento y documentarlo en fotos y video. También cedió una copia de la carta de postulación que escribió el Profesor Pedro Luís Hippolyte, antiguo docente del LTAD y actual Coordinador de Investigación de la EACRV – FAU – UCV, de la cual cito:

“A lo largo de su carrera profesional, por más de 50 años, se le considera pionero –en Venezuela- en el campo de la Computación aplicada a la Arquitectura. Fundó en el año 1974 el Laboratorio de Técnicas Avanzadas en Diseño, el cual durante sus 30 años formó estudiantes, profesores e investigadores en la […] Universidad Central de Venezuela y otras universidades del país. En la Facultad de Arquitectura de La Universidad del Zulia impulsó y desarrolló la opción de computación en la maestría de arquitectura.

Ha sido un visionario en el uso de las nuevas tecnologías aplicadas a la arquitectura como la Realidad Virtual, Comunidades Virtuales, Educación a Distancia y las Tecnologías de Información y Comunicación; promovió y desarrolló los primeros encuentros virtuales en Internet […].

Fue uno de los miembros fundadores de la Sociedad Iberoamericana de Gráfica Digital – SIGRADI […]. Participó y coordinó los Congresos Virtuales de Arquitectura 2000 – 2001, Congreso Venezolano de Aplicación de Computadoras en Arquitectura CONVEACA 1999 y 2001 […].

Es un investigador nato; así lo demuestran los numerosos artículos publicados en revistas especializadas y conferencias magistrales dictadas a nivel nacional […] e internacional […].”

Nosotros, los antiguos integrantes del LTAD nos llenamos de alegría y orgullo de ver a nuestro maestro ser reconocido después de tantos años de valiosos aportes a nuestra disciplina y a nuestra Alma Mater.

¡Muchas felicitaciones, Gonzalo!

AA - NAi Design Workshop São Paulo

From July 16 to July 24 I’m going to collaborate in the workshop: Micro-Revolutions: AA – NAi Design Workshop São Paulo (AA Visiting School), at Espaço de Cultura Contemporânea Escola São Paulo, which promises to be a great event:

The goal of the joint Architectural Association and Netherlands Institute of Architects (AA- NAi) Design Workshop in São Paulo is to explore the rehabilitation of otherwise obsolete, residual and overlooked urban environments, communities and physical materials, through critical urban analysis seminars, as well as through the use of innovative computational design and digital fabrication processes. […]

The intense, studio-based workshop, which will be open to designers from all over the world, will include extensive digital parametric modelling design tutorials using Rhino Grasshopper and Rhino Scripting, computer-numerically controlled (CNC) fabrication, including rapid-prototype, laser cutting and CNC routing and milling. Evening seminars and a full-day Forum will include lectures and contributions from both Brazilian and international architects, designers, urban planners, street artists, photographers and other specialists. […]
