Humans

A nice how-to below: adding figures to a scene.

We’ve been having a long conversation with our photographer recently about human figures in architectural photographs and renderings, with that conversation spilling into our design studio as well.

In our view, human figures in an architectural rendering need to remain anonymous. We have previously intimated as much.

Bad examples of architectural presentations use human figures like candy sprinkles on a dessert that’s already too rich, or a liar who talks to much, or buildings that need signs to point out where the front door is. These things don’t help and are not fixes. Just stop.

We do want to see past the sprinkles and think about the scale of the architectural space proposed. We want the verisimilitude, the invitation to a possible future. We don’t want to be distracted by space invaders, thinking about who these people are, where they got their hair cut, or what they might be really thinking about.

Which is why they often turn their backs on us.

Or skulk in the trees.

Or move faster than the shutter speed – feeling safer behind the blur.

Or being ‘lonely in the modern world’ they quietly sigh and wait for us to finish the render.

Or try to quickly move out of the frame.

(N.B. The first three images above we think are pretty good. The last two technically excellent but alienating. Image one is Foster’s Apple campus. The others are all from the developer package selling Renzo Piano’s London Shard project. Mostly good, but some not. Here is an interesting, if scary, example, a scariness relieved only somewhat after reading about the particular and weird building brief, but, still.)

In seriousness, it has always been thus: creating a quality architectural rendering requires training the fine arts, knowledge of color theory, an intuition about perspective and composition, and an understanding of how to reinforce a narrative and communicate visually. In the digital present, days, it also requires the digital skills to correct the fall of light on a figure, to artfully anonymize it, the ability to properly add shadows and reflected light and to feather it into the scene. Even a quick plan sketch is a tangled network of choices of what to foreground and what to background given the intent of the drawing. A representation in three dimensional space more so.

And per the conversation referenced above, figures, people, models – call them what you will – and messaging gone off the rails are just as much a problem for architectural photographers, especially as the line between the photograph and the CGI becomes finer. We don’t want our figures to be made fun of. Oh no.

For Photoshop skills, look for some technical how-to in the video above – with plenty more where that came from. Keys to a beautiful visual narrative can’t really be put into a checklist or tutorial, although many have tried. Critique checklists are sometimes informative. The American Association of Architectural Illustrators has an annual competition – which you’d think one could learn a lot from, but to look at the latest publication there is surprisingly little there there.

The three images below grabbed off our boards, certainly aren’t polished perfection, but we like the speed with which they were created, and how strong a communication tool they are for informal design updates both within a design team and with our clients.


During design, at BDA we find it convenient to render figures directly within Artlantis and take advantage of quickly moving back and forth between active designing and reflective assessment. Post-processing to get the figures right makes for a less efficient workflow – but for important public-record renderings the figures certainly need to be “right”. Packaged 3d scalies or renderable 3d figures are almost never perfect out of the box, but they are perfectly adequate for scenarios where brisk efficiency is more important than perfect photo-realism, which in a busy small design office is… almost all the time. And often we don’t bother with figures at all, knowing that a space can speak for itself if the space is well-designed and well-presented.

Verisimilitude is a slippery slope. Figures can be semi-transparent in-motion ghosts, as in time-lapse photographs, or you can shoot for natural realism, raising the bar and your time commitment by an order of magnitude with the sudden need to get the lighting, palette, composition, composure, and emphasis right. Before you know it, you’re as wrapped up in the blocking as Raphael must have been when painting the School of Athens, although I think we’ll agree his intentions deviate a bit from the intentions of the typical twenty-first century architect rendering a scene.


As it has always been with architectural representation, the goal is to get to the point. Transmit the right message: what the space is like, how the light comes in, how it might feel to be there.

Antitesselationism

A skilled GDL scripter is capable of producing amazingly clean objects, but the catalog of clean GDL objects is not as deep as one would like it to be. (See the sidebar links here in bd-MAP for access to some of the GDL catalog.)

So we rely on third-party catalogs from time to time, but the objects are often polygon nightmares. AC 16 has a new tool and a new way to clean them up.

Clean is good.

Modern Base Details

We talk about this detail a lot. Here’s another conversation.

Print Me

News: bd-MAP prints nicely now.

Geekery: The web is not designed for printing, and even as it is, Chrome browsers will not print the required background colors of tables. Firefox and Safari work nicely – just be sure “background colors” are enabled in the print dialog.

Africa

This took me by surprise.

Insulation Roundup

The BGI Insulation Report is on our server under reference/material guides. Six HSW credits! Go for it.

Keeping 4-5-10-30-60 in mind, here are the best choices by application, considering the greenness of the material only. In practice, moisture dynamics, air leakage, condensation, and assembly mechanics might make the second-best right for a particular situation, but most of the time it’s easy to stick with number one.

Recommended (not Code) Insulation Values?

For moderate climates, the recommendation is: 4-5-10-30-60.

That is: R-4 windows, R-5 under slabs, R-10 foundation walls or slab perimeter, R-30 above-grade walls, and R-60 in the attic or roof.

Condensation Roundup


Give Mr. Water and inch and he sneaks in to take a mile. The Cloak of Vapor Invisibility is one of his best disguises.

Here’s a little quiz:

Do you know our climate zone?

Do you know the thickness of rigid insulation required by code on the outside of wall sheathing?

Do you know the required thickness of rigid insulation above the roof sheathing, for unvented cathedral ceiling assemblies with vapor-permeable insulation below the sheathing?

Do you know where the vapor barrier should be placed in a wall in our climate?*

Did you know that the best insulation comes in a board version that is rigid enough to screw 1×3 furring strips through without deflection?

Do you know the correct techniques for specifying and installing dense-pack cellulose insulation in walls and ceilings?

Do you know where to get ROXUL mineral-wool insulation locally?

We use walls to climate-control an interior, and also, weirdly, for the distribution of pipes and wires. Do you know that one of the best ways to vapor-seal your residential wall assembly also sorts out the pipes and wires from the insulation, thereby improving effectiveness of both?

Do you have good ideas about how to get a vapor-seal to span the band board required by standard western platform framing, when a vapor-seal is indicated by the building’s climate zone?

What does your thermal barrier checklist look like? Here is the one provided by the 2009 IRC.

And finally, do you understand the difference between a vapor barrier, a vapor retarder, and an air barrier? Do you know how to properly deploy them in our climate? Did you know that for tricky hot/cold climates like that found in Virginia, there is a vapor retarder with seasonal intelligence?

* ATBVO is the acronym to keep in mind for Virginia, according to our favorite energy consultant. “Air tight, but vapor open” to both sides.

Ten Steps to Becoming the Designer You Want to Be

Good advice from a self-described mentor and design veteran.

  1. Get the book
  2. Get the obscure book you’ve never heard of
  3. Choose a topic that fascinates you and learn it inside out
  4. Write, blog, and speak on that topic
  5. Learn Something New Every Day
  6. Create a New Idea Every Day
  7. Experiment
  8. Learn as many frameworks as you can
  9. Choose variety over anything else
  10. Model or draw (all the f*@#ing time)

An open letter to the next generation of designers, part 1.

Everyone has moments in their career when they look back and think, “If I had only known then what I know now….” After 15-plus years as a designer and design researcher at places like IBM, Trilogy, M3 Design, and now frog design, I know I certainly have. Which is why, now that I’m a veteran, I’d like to give share some advice with young designers just starting out. If I could be your mentor, this is what I would tell you:

Footnote:

The obscure book referenced above is The Universal Traveler: A Guide to Creativity, Problem Solving & the Process of Reaching Goals. I discovered this book as an undergraduate in architecture school and I am sure my teachers hated seeing such a hippy book in their studio. Maybe they were on to something: I found the book’s language unfathomable. I barely understood what it was about. Yet it spoke to me, and apparently some seeds were planted. So we have bd-MAP: not a Universal Traveler – as we’re trying to get a rather specific type of work done. bd-MAP would be your Specific Traveler According to Universal Themes.
