We all know that computer technology has done a lot to advance not only the way the design process can work, but also to improve the constructed outcome of that design process.

That’s why I think it’s important to shed some light on what “aural renderings” can do. (1) You, as an architect, can actually listen to a designed space as built to the parameters of your three dimensional CAD model. Here is a detailed description of the process that goes into creating such an aural rendering:

A 3-D model of the space is built using CAD software, and this model is transferred to an acoustical modeling software package. The acoustical consultant assigns acoustical properties to the modeled room’s surfaces (or potential construction materials) and places sound sources and listener locations. The software then calculates the propagation of sound from the source to the listener using algorithms based on ray-tracing combined with statistical reverberation calculation and other techniques to account for sound scattering and diffraction. The calculated room impulse responses are then convolved with audio material that has been recorded anechoically – in a space free from echoes or reflections – to generate a realistic and listenable result (a piano recital, a busy wedding banquet, or a ceremonial speech as it will sound in the yet-to-be-built space).

EXPERIENCING YOUR BUILDING BEFORE YOUR OCCUPANTS DO

Yes, you can visualize your building’s design and perhaps its final outcome, but so many variables are at play once the building is constructed. Can you be certain that your designed spaces will not only function, but also feel the way you intend?

Simulation technologies can be an extremely helpful tool to you during your design phases. And they can be quite valuable as you must make many decisions during those phases to produce a quality architectural design that realizes your vision.

For instance, the aural qualities to a space may not be so evident in a fly-thru animation; however, an aural rendering may make that space come alive in a way the fly-thru does not. As you know, different modeling techniques can inform you of different things.

As technology develops with new ways to “visualize” your complex architectural designs, wouldn’t it be nice to have a way to fuse them together? Why not visually render a space capturing its light levels at a specific time of day while also aurally rendering how it will sound during a specific function?

Really, the possibilities (and opportunities) become endless. The key is to pull the best of what technology has to offer so you are informed with vital information that helps you make great design decisions.

Don’t use computer technology as a crutch, but strive to push the boundary with them.

COMPUTER VISUALIZATION FOR DESIGN

3D visualization has become such a part of the architectural design process in many firms. Architects use virtual model-making for many reasons.

For instance, 3D computer visualizations help teams to make design decisions by testing different solutions as they create. Also, 3D visualizations help to communicate architectural design schemes to consultants and clients.

All in all, visualizations have made their way into not just helping to produce construction drawings, but also, as a way to communicate design ideas to an array of other involved parties.

VISUALIZATIONS AFTER A DESIGN IS BUILT?

A team of computer scientists at the University of Washington’s Graphics and Imaging Laboratory have developed algorithms to be used with Microsoft’s Photosynth. The big idea behind their work is to create a “collective” visualization where a 3D model is constructed from a repository of Flickr photos of an urban space. So far, they have reconstructed the small city of Dubrovnik and several famous Italian landmarks.

By using a puzzle-like approach to stitching together photos taken by random tourists, the resulting visualizations make me realize the significance to a “collective” approach to perception — especially with the increasing social and dynamic nature of the internet.

As social media becomes more popular and increasing amounts of data are collected, visualization techniques will really be able to place our architectural treasures (and non-treasures) within a dynamic and virtual “time-capsule”.

I wonder what these sort of “collective-visualizations” will look and feel like in the future? Will they be somewhat true to the original or will they take on an architectural spirit of their own? Will architecture move on to a new sort of virtual after-life once it is demolished?

What will be the ultimate purpose of such collective visualizations? Will they exist as a truer collective memory of our real-world buildings, or could they augment present-day architecture that is still in use? Will we have a sort of architectural “Second Life”?

THE NEXT GENERATION OF A MAP

Sameer Agarwal, an assistant professor at UW who worked on the project said this about potential uses for the technology they’ve developed…

Agarwal said the technology could be used for everything from video games, to next-generation GPS, to preservation for the sake of posterity.

Venice is slowly sinking into the lagoon that surrounds it, for instance, and a 3-D tour could digitally preserve the city for future generations. Earthquake-prone cities could be catalogued, both for history and for municipal planning efforts.

“If you have a digital representation of something, then you can study it. Maps only offer you a limited view,” Agarwal said. “There are a number of very different kinds of uses for something like this. And there’s just the pure science aspect of it, which is advancing how you can do large scale 3-D construction.” (1)
