Knowledgeware Optimization

This tutorial introduces the knowledgeware warning function and multi-parameter optimization. In this tutorial I model a simple room and use its dimensions and configuration to analyze surface area and volume. Using the values, the reverberation time is calculated. As a first attempt at using the engineering optimization tools I let the software determine the room dimensions based on appropriate reverberation times.

Unfolded PowerCopy

Tutorial that explains how to include unfolded geometry in a powercopy.
The tutorial also shows how to use local and global parameters.
18 minutes. Click the image for the video.

Arts & the Environment: FIRE

As part of a University of Michigan initiative to explore arts driven inquiry, Arts on Earth sponsored multidisciplinary faculty teams to develop work that explores environmental issues. Since the summer I have been working with John Marshall from the School of Art & Design and Werner Dahm from the Laboratory for Turbulence & Combustion (Department of Aerospace Engineering). We were given the element of fire.

The opening night of the installations / performances is on: November 5 from 5 - 11.
Here is a link to
Arts & the Environment.

A series of aluminum forms will hold an array of autonomous interactive units that will respond to the movement and environmental conditions around it. The behavior is obviously informed by the dynamic qualities of fire.

Random Numbers linked from Excel

This tutorial will describe the creation of a design table, allowing for the control of geometry from an Excel spread sheet. The design table is also useful for input and output of data from Digital Project. Using the random number generator from Excel, a rule is created to randomly open or close the geometry of a powercopy.

Digital Project - Tutorial 2 - Surfaces

Here is the second Digital Project tutorial developed for the ParaMod Seminar.


It is 65 minutes long and builds on tutorial 1. Here we will use the first sketch to drive the height and shape of the covering surface. At this point the form is less of a concern than learning how to develop the interactions.

Digital Project - Tutorial 1 - The Sketch

Here is the first Digital Project tutorial developed for the ParaMod Seminar. It is 42 minutes long and covers the interface and the sketch. Let me know if I left anything out.

ParaMod Seminar: Structural Density

It is that time of the year; back to school. This semester I will be running the ParaMod grad seminar at the Univ or Michigan School of Architecture. Rather than work with a different topic I am continuing the work that we started in the spring term. The seminar will again be looking at the relationship between structure and organization. Obviously the associativity and intelligence of the Digital Project modeling environment allows for various ways to explore the topic.

The plan is to post samples of the student work to share the research. A series of video tutorials will be developed to support the seminar work. I will be posting these tutorials here too.

Here is a link to the syllabus for the seminar.

Parametric Wooden Strips

Here is an in progress project from our office. The small restaurant interior will be built with wood strips for the benches, bar, and ceiling. Keeping the strips vertical allows for them to be bent around the corners. Where the form pulls and pushes, light comes between the wood strips from behind.

A series of conical forms are used to control the radii of the wood strips. The more extreme the cone, the more open the gap in the strips.
A simple Catia diagram demonstrates the relationship between the cones and the strips. The parametric model allows for quick feedback between the manipulation of cone and the redulting affect of the strips and gaps.

Here is a link to a video of the Catia file.

Back from traveling

Sorry for no posts in a while. I just got back from a trip to Argentina and Uraguay. We lectured in Rosario and decided to spend some time there. Juan Rois from UIC organized a number of visits and meetings while we were there. We got to meet some of Argentina's best architects, went to their offices, and visited their projects under construction. Here is a sampling of the buildings (click for larger image).


We saw some amazing projects. The architects were all very open and interested in talking about similarities and differences between architecture and practice. The most striking difference is the role of labor. In Argentina the labor is less expensive but the materials are more expensive in comparison to the US. As a result, the use of brick and concrete (cheap materials) is more widespread and of much higher quality. The craft and time taken to build with masonry or fabricate on-site formwork is not a fearful proposition as it is in the US.

On top of Casa View with Diego, Juan, and Marcelo.

Waiting for our table. With Gerardo, Marcelo, Luis, Juan, Craig, and Jen.

And the steak... We ate some very good Argentinian beef while drinking very good wine from Mendoza.

Spiral Revisited

This grasshopper project builds on an earlier exercise that built a spiral using simple transformations. While it is relatively simple to define a spiral mathematically, it is difficult to modify the strict form using the expression. If you are interested in the expression for a spiral, here is a link to the Google group posting.

The goal for this project was to have the first few points lay flat before changing elevation. The thought was this would give it a stable base.

Projecting the shape flat then allows for the creation of the "V" column at the termination of the spiral. A split, subset, and interval are used to create spokes between different parts of the spiral.

Intro Rhino Tutorial 005 - Output: Maxwell Render

This is the 5th and last of the Rhino Intro Tutorials. The intro tutorials were completed for the incoming 3G1 studio for their second assignment. Additional Rhino Tutorials will deal with more advanced issues.


This tutorial takes the model from the previous tutorial and creates a simple exterior rendering. A sky and people are added with a couple of simple tricks in photoshop.

Here is a link to the 25 minute video tutorial.

Spiral Structure - Grasshopper

While it is very easy to make a spiral with an equation, I took the approach to make a series of points that build (and translate) from the previous point. Once a series of 10 points have been created, an interpolate curve connects them and then these curves make surfaces. Dividing the curves a series of pipes connect points to form an in between structure.
As more rotation occurs between points, the curve must interpolate, creating oblong cuves.


While the file is not as elegant as I would like, the file includes shift and interval as a way to connect the various divide points. If anyone has a better idea how to repeat the multiple actions of the spiral, I would be open to hearing about it. As far as I know there is no loop function which would do the trick.

Illuminated Surface

Here is a small project that I have been working on for part of an installation. The surface (about 3'x3') will act as backdrop and light for a small table in a gallery. A series of back lights will be controlled interactively through interaction with furniture in the space.


Two splines are used to control a series of surfaces and the toolpaths used to mill the surface.


Here are the lines overlaid on the surfaces. At various points the surface splits to allow a small aperature to move from behind. The various iterations of the line drawings are made through the movement of the two splines. Digital Project was used to define the relationships and only after everything was worked out, the splines were modified to approximate the final proportions of the splines and aperatures.


The two renderings show the light from behind as trapped between the two surfaces. The final piece will be milled from plywood.

This series of models is more of a proof of concept for the aperatures. A new model will be developed using the splines, but using a different method to create a model with thickness. The current iteration is only one surface.

Digital Project Honeycombs

The post for today is an excert from a project that used digital project to build responsive honeycomb structures. The main goal was to work with rules (rule firing in digital project). In this case, as the cells are stretched, the average cell size is computed. The light gray shows the geometric constraints for the cells.

Then as the individual cell is made larger or smaller than the average size, it is made deep/shallow or thick/think. This variation is visible in the iterations below. This level of analysis adds a level of removal from the designer. One cannot be sure where the depth will shift.

Variations are rendered to give some sense of the range of variation possible. I will be gearing up for class in the fall and will post tutorials on document templates and rule firing, check back.

Point Distance Surface

Building on a couple of the Grasshopper tutorials and trying to include a couple of new commands I developed a surface that responds to a location of a point. The video shows the interactions of the various sliders.



video

For a bigger video click here .


Making a few tweeks with the sliders and then baking each, the variations from a screen shot below. Unfortunately I could not find a way to trim in grasshopper so this task is completed once the geometry is baked.



When selecting the point, make sure "point" is selected in Rhino. If "coordinate" is selected you can make a point, but you will not be able to move it around.




Revised file based on some feedback from Gabe. My trim is a bit messy because I could not get it to subtract the correct side. I exploded the surfaces to get the final trim. Here is a link to the grasshopper file.
