Digitala tredimensionella visualiseringsmetoder : ett sätt att kommunicera landskap

Abstract: This thesis investigates the possibilities offered to a working landscape architect by anincreased and altered use of digital 3D environments. A basic assumption is that increased useof digital three-dimensional environments promotes the creative processes and presentationoptions of landscape architects.The thesis is based on literature studies and communication with working landscapearchitects, and includes an investigation of the visualization methods available in the Blender3D modelling software. The thesis provides a thorough survey of what it means to model inthree dimensions, as well as of what modelling methods are feasible for a landscape architectto use. As landscape architects, we work with human and unique processes, and thus it isdifficult to develop standardized and automatic software for our profession. One possiblesolution is to turn to open source development, where software and models are shared andanyone can contribute. Especially interesting is software supporting game engines, which maybe a suitable tool for modelling as well as for presentation.The primary advantage of 3D modelling is the way it allows us to experience and investigatesuch aspects as spatiality and proportionality in a dynamic setting. As landscape architects,our creations are never static but always dynamic, and this should be conveyed to ouraudiences and contractors. The primary disadvantages of 3D are that modelling is timeconsuming and difficult, that digital imagery often comes across as impersonal and strict, andthat digital renditions tend to be interpreted as final suggestions, even at an early stage ofdevelopment.3D models can be divided into three main categories according to intended use: twodimensional,animated, and interactive. The subdivision is fluid, and a 3D model may evolvefrom one category to another in the course of development. Models can also be used indifferent phases: initially as an analysis tool, later as a sketching or working model, andfinally as a presentation model.With the use of digital 3D modelling, we can see, experience, understand and convey a sitebefore it has been built, as well as evaluate its design at an early stage. A two-dimensionalimage always shows a portion of a whole, never the design in its entirety. Increased use ofmoving images, multimedia and virtual realities adds qualities to the planning and projectingprocesses and may also, through communication channels such as the Internet, improvecitizen dialogue concerning larger projects. This, in turn, may lead to a vitalized democracyand an increased awareness of the landscape architectural profession. Extended use of 3Dtechnology may generate as yet unknown fields of application that may strengthen and extendthe role of landscape architects in society.
