| summary |
A rich vocabulary has evolved for describing architecture.
It serves not only as a means of communication, but also as an
embodiment of concepts relating to form, space, structure, function, mood, and symbolism. We architects not only speak in
terms of walls, rooms, roofs, arches, etc., we see in terms of them
and think in terms of them, as well. Such concepts are integral to
our ability to design. Typical CAD representations, however, are
based on geometric/mathematical elements like points, lines,
planes, and symbols. Even more experimental approaches like
parametric shapes or procedural assemblies correspond poorly
to architectural elements, and seldom lend themselves well to
making conceptual changes that would allow exploration of design alternatives. Small wonder some architecture schools experience a division between computer and studio courses, or even
between computer and studio faculty. Different ways of talking
and thinking are involved. The concepts involved are often mutually exclusive.
This paper discusses an attempt to address this conceptual
mismatch, using what are termed “protean” (meaning “very changeable”) elements. These are high-level elements corresponding to
architectural concepts like “wall,” or “dome.” They each have
parameters appropriate for the particular type of element they
represent, and produce the polyhedra necessary for graphics
based on these parameters. A system is being implemented to
allow models to be constructed using these elements. The protean elements form a loosely structured model, in which some
elements hierarchically contain others, and some elements are
essentially freestanding, being created and manipulated independently of other elements. Characteristics of protean element
are discussed, including the underlying object-oriented structure,
the relationship between elements and graphics, and functions
associated with the objects. A scheme is explained whereby all
parts of a design can be represented even when the design
includes extremely unusual forms not conforming to predictable
classes of elements. The necessary support framework is also
discussed; general flow of the system and mechanisms for viewing the model and editing subcomponents are explained.
The current status of the project, and intentions for future
work are discussed. The project has been partially implemented,
and the necessary framework to support the system is mostly complete. |
