"[...] When I look outside the door what do I see? An airplane flying over, a car passing by. Everything is moving. That is our environment. Architecture should deal with that.[...] Frank.Gehry There are many words written about the motion in architecture. (Giedion, Ferstegen, Jormakka, Lynn). They try to describe, classify, separate or represent it. This work presents motion as one of the leading factors of contemporary ways of expression in architecture. It will examine different examples of architectural motion, then make a hypothesis, that one of the possible reasons of expressing movement in architecture is the usage of new generation of modern CAD/3D-animation software, like 3DStudio Max, Lightwave, Maya, Catia, Rhino, or CINEMA 4D. Because of availability only chosen features and tools of CINEMA 4D will be described further. Motion can be expressed in architecture in two ways: by the procession or by superimposition. [Lynn,1998] In processional models of time, architecture is the immobile frame through which motion passes. It is based on static frames and have fixed relationships between functional program and user. The elimination of force and motion from form is the basis of recent alternatives (e.g. sequential model). Through the multiplication and sequencing of static frames it introduces the idea of "dynamic" architecture as multiply framed. An alternate model of time and motion resists the separation of form from its animating forces. Form is perceived in a space of virtual movement and force rather than within an ideal equilibrium space. Instead of fixed prototype, a flexible, mutable models are created, which are rather a potential of multiple variables ("performance envelope"). In result "architecture can be modeled not as a frame but as a mobile participant in dynamical flows." [Lynn, 1998] To do that, necessary is more than a shift in technology, but rather a shift in sensibility from reduction to combination to compose time based, topological designs. Although the introduction of time and motion techniques into architecture affects visual qualities, it is inappropriate to understand technology in terms of style.
