That’s a very impressive amount and depth of study, Jerry. In order to help clarify the workings of such a complex model for the tutors at the final presentation (and for potential users of such a system) could you make some additional explanatory diagrams:

1) relating the variables to plans and sections (or whatever is most appropriate) so that it can be seen directly where a particular variable will have effect; and

2) relating the variable to each other, and to final and intermediate results, so that the chain of dependencies is clearly visible (of course, the GC graph is supposed to do this, too, but I’m sure you could improve on that method of display)

Thanks.

It seems you’ve had a long, hard struggle so far, Bert, but you’re getting close. I’ve gathered that your main strategy is to present differently lit renderings of the same scenes, for a collection of scenes. So when setting up the survey, it would be good to cross-check people’s responses somewhat by, presenting the scenes in different ways. For example, you can show the same scene with two or more kinds of lighting, but then also present two or more different scenes with the same kind of lighting. (Also, the angle of view can have an effect on people’s impressions, so it might be useful to include a few oblique (non-central) views for examining this.)

Thanks for posting this material, Rein. Can you find some way to reduce the number of calculations and/or simplify your model (for example to a single floor, as we suggested last week) so that you can draw some intelligent conclusions about the system’s behavior and feed those back into your design without having to spend a week just running analyses?

Now you’re starting to get some interesting results, Christian. It would be good to see more clarification of the operations (explosion, booleans, etc.) which generate your forms. Then, your next steps could be both taking those operations deeper, to better articulate the architectural organization (not just a skin – though the two skins do make some progress in that direction) and also changing the rules/operations and/or the inputs to those, to see what effect these have on the outcomes. One example of this is, of course, your stated goal of testing the effect of various street patterns on the building form. But you can also look at what effects result from changing the relationships between the context and the project.

(And when presenting your research next week and preparing your report, please be sure to include images and diagrams which support the claims and explanations you’re writing here.)

Hi, Rein The work on the lighting analyses you showed last time we met looked good, and it would be great if you could post here a summary of it - as well as things you've been doing since then - for the benefit of the tutors and in preparation for next week's presentation. Thanks, AC

So, Auke, how's it going with modeling additional variants to try improving on the problem of keeping the floors horizontal, which you pointed out in your last presentation? By the way, it would be great if you could post a summary of that presentation, since it was a good example of the feedback process: building models to answer a question, looking at the results, and then doing further exploration to improve the results. Cheers, AC

ps Please turn on display of all comments you've received (see examples of your classmates' blogs 'Recent Comments', etc.) for the benefit of the tutors reviewing and commenting on your work. Thanks!

It's been good to see the way you were able to realize some of the strategies we discussed for translating your analysis results into 3D models of the facade, Arjan. Have you been able to work out the errors you mentioned when trying to model variations in placement of openings? If not, perhaps you could rely on your earlier experiments with introducing openings into the facade and instead look at the possibility of using different materials in the tension and compression zones, as a way of tapping into this difference for a source of expression.

Really impressive effort on the physical modeling and actuation challenges, Arnoud!

Are you seeing any feedback from this to your ideas about how to incorporate such a tensegrity mechanism into your architectural designs? AC

Hi, Bert

If you’re still not getting satisfactory results from rendering with colored light, I’d suggest you change your approach to coloring the surfaces of your model(s) via their material settings – as is more commony done – and using neutral-colored (e.g. white) light. In this way you can avoid losing more time to technical problems, and it will also give you more control over the scenes you generate, since the monochrome and two-tone images you presented so far do not seem really usable.

So don’t get hung up by the software choice – do whatever you can to achieve some satisfying and meaningful results in the time remaining. (You can even produce differently colored scenes by hand and put scanned copies of them into your surveys.)

e-mail from/to Christian:

... yes, Christian, I think this model is showing something more in the spirit which you seemed to be seeking.

However, here, too, as in the model on which I commented earlier today, the spatial effect(s) of the context upon the site/project are still quite simple. So in order to generate the level of complexity needed to really begin architectural 'space-making' I thought that you could use the 'irregular diagonal' model from earlier in the place of your proposed new building.

One way of doing this, I believe, would be to set all of the height control points of the building footprint to zero (or small, anyway) while leaving the surroundings at various heights, and then placing the 'irregular diagonal' model onto the site. Next you could look at ways of linking its control points to the context, rather than being 'independently' driven. This way, you may be able to generate complex (irregular diagonal) building designs both from a rectangular street pattern and from more complex streets patterns like the one you're showing here. I hope this is clear, but in any case we can discuss it further on Monday.

Have a good weekend!

Andre

ps I'll post these e-mails to your blog, also, so you have all comments collected in one place. I don't see any comments (neither mine, nor anyone else's) appearing on your blog, though. It would be helpful for the instructors/tutors to be able to see those also, not only what you're posting yourself, so please turn on the comment-publishing functionality of your blog, if you are able. (If not, see the blogs of some of your classmates, where links exist for 'Recent comments', 'Latest comments', etc. Thanks!

Subject: RE: [cvangruijthu] New comment on "Parametric deconstructivism"

Hi Andre,

Thank you for placing a comment on my post. I also agree that the results as shown in the blog 'parametric deconstructivism' are not really what I want to achieve. I understand from out your comment that it would be the best to bring back the adjustable irregular / diagonal streetpattern and relate this to the new to rise design? At this moment I got a model the same as 'parametric deconstructivism' but with an adjustable streetpattern. By adjusting the streetpattern I create the irregular, diagonal negative volumes which forms the streets within the city-grid. Also the footprint of the new to rise design changes. In the supplement I attached a quickly made render from the model as it is now. Do you think I approach this way the research question more then the model you gave comment on?

Greets,

Christian

It seems you’re beginning to find ways of relating your project’s context (in this case the buildings surrounding your site) to some of the characteristics of your proposed design, which is the basic aim of your research. It’s not clear, however, whether the relationships and results are those which your really want – expressed for example in your earlier model of a volume subdivided with irregular, diagonal negative volumes, which we suggested on Monday would be a good starting point for the proposed design, rather than for the surrounding context.

Therefore, I’d suggest that in addition to the exploration of modeling other contexts, which you’ve said you’re planning next, you should also try implanting that earlier model into the grid you currently have, in order to see what effect a different set of relationships has within the same context.
