The reading begins with a quote linking modern technology and its very close effects on architecture. It praises Joseph Paxton’s Crystal Palace as a bold building for its time, leaping forward technologically and materiality as an architectural marvel. This building saw criticism as not being “architectural” because of its method of design, materials, and assembly, which were all unconventional. Similar criticisms may be drawn to modern designs with heavy computer influence or complete conception.
Technology and its infinite abilities open up new dimensions in design. This is all fairly recent, only in the last few years has computer aided design made such great advancements and had the potential for such commanding influence on building design. Advanced programs help make very difficult and expensive buildings to design constructible. The author relents that initially, digital “architectures” reject conventional methods and influences, those contextual or functional, instead seeking to be experimental. However, this new style is not without precedent. It too tries to go break tradition and “establish norms of beauty and proportion in architecture.” Those two conditions can be met through parametrics, as explained later.
“Smooth” architecture, implementing curvilinear shapes, has been formally ignored or dismissed by many architectural forms for being difficult to spatially comprehend or construct. The author figures there is basically no excuse for this considering curvilinear forms are very familiar to us, in the forms of consumer products and spaces in the likes of cars and airplanes. “Blobs,” or smooth surfaces created digitally, and “boxes” should not be seen as completely independent of one another, but as similar forms on a “sliding scale of formal complexity.”
The author makes comparisons between ships and buildings, which are surprisingly similar from a design perspective. Designing each requires many of the same requirements, principles and methods, with a nod to shipbuilding in terms of complexity and difficulty. As such, architects have historically taken precedent from shipbuilding. “Frank Gehry’s Guggenheim Museum in Bilbao would not have been possible without the local steel and shipbuilding industry.”
Architecture borrows techniques from other practices. Animation software, such as Maya, was originally developed for use in films, but is often put to work architecturally. Architecture borrows from product design, automotive, aerospace, and shipbuilding industries. Each large step in technology of these industries makes a considerable impact on the designs possible. The Boeing 777, which was “the first 100% digitally designed aircraft,” serves as a good example.
The next chapter deals with digital morphogenesis. Architecturally, digital media is becoming more frequently used as a generative tool for making forms only possible digitally, and not solely for representation. So essentially using computers to do the designing work based on specifications is becoming more common. When this is done, drawings like plans and sections don’t “generate” the design but rather seek to analyze it. This is a methodical shift from the “making of form” to the “finding of form.” In generating these forms, computers are concerned with topology, which is “a study of intrinsic, qualitative properties of geometric forms that are not normally affected by changes in size or shape.” Topologies “remain invariant through continuous one-to-one transformations or elastic deformations, such as stretching or twisting.” This differentiates them from curved surfaces.
Pre-digital architecture is limited by Euclidean geometric forms and simple shapes like lines, circles, and quadrilaterals. With this traditional method, constructing complex curves relies on the utilization of these simpler geometries to form them with greater complexity and difficulty. NURBS programs, which stand for Non-Uniform Rational B-Splines, bypass this. This system uses a combination of elements called control points, weights, and knots to define topologies. It can create a wide range of geometric forms, from simple lines and Platonic solids to much more complex surfaces. It is also an computationally efficient way to represent geometric forms.
Parametrics are tools that can help determine form by “describing a range of possibilities.” They are essentially rules computers use to generate form. As such, the design parameters are declared, not the shape of the form. Different objects can be created by assigning different values to these parameters. The International Terminal designed by N. Grimshaw and partners demonstrates this method in its irregular roof form. A parametric model was used to make the arches of the roofs instead of modeling each one individually. Parametrics profoundly change the entire nature of design. “For the first time in history, architects are designing not the specific shape of the building but a set of principles encoded as a sequence of parametric equations by which specific instances of the design can be generated and varied in time as needed.”
Parameter based design takes into account the unfolding of the internal system (program) and the enfolding of contextual information fields (responds to the context). Parametrics can accommodate both. Animation programs can be used to determine the forces that represent the unfolding and enfolding of different information fields. Greg Lynn did this first with animation software depicting the kinematics, or the study of the motion of systems of objects. This software sees forms as the reactions of forces, an idea echoed by D’Arcy Thompson in a book published in 1917.
Biological “rules” and genesis can be applied to the generative process for architectural form. Architectural concepts are expressed as a set of generative rules, which set up digital parameters. A morphological process basically takes different randomly generated designs that fulfill certain parameters and crossbreeds them with one another to create a sort of vertical evolution.
Performative architecture, which is beginning to take hold, is used for the design on cities, buildings, landscapes, and infrastructures. It places the performance and use of spaces above form making. It can be described as parametrics with an emphasis on program.
The reading ends on a note of caution to see digital design simply as a different method and not more than what it is. The author suggests that it should be scrutinized and considered on an equal platform as any other architectural methodology.
