Abstract
In architecture, the computer is becoming the main tool of communication. The majority of orthographic, axonometric and perspective drawings are produced in digital format and Architects bene!t from the speed, power and precision with which drawing is done. However, the quickness and accuracy of the computer causes a sense of negligence. With powerful 3d modeling and rendering programs, visions of new architectural ideas are created with ease and represented similarly. Perspective renderings are quickly set up, rendered and presented authoritatively. In these new processes the art of representational perspective renderings is forgotten. Despite the precision and accuracy of the computers many renderings fail to achieve the level of success attained by beautifully constructed perspective drawings. While there are a handful of brilliant CGI artists, there are more students and practitioners of architecture who could bene!t from a proper understanding of quality rendering compositions. Therefore, the topic of inquiry is digital architectural rendering. The focus of this research document identi!es the rational, consistent and fundamental qualities of architectural renderings that cause them to be identi!ed as of higher quality and organizes the principles into a practical systematic guideline that can be applied to the construction of digital architectural renderings for both the novice and expert practitioner of architecture. Hypothesis I There is a fundamental set of principles to the construction of digital architectural perspective renderings, that when applied, will improve the quality of the architectural rendering representation. Research Methodology I Based on the assumption that a set of rendering principles exist and are quanti!able, two research strategies were pursued. The !rst phase of research examines case studies and identi!es three separate categories of architectural images for analysis; contemporary digital rendering, historic perspective rendering and architectural photography. Through comparative analysis, two systems, a grid overlay and a data collection chart, record information for each category of images. The resulting information identi!es a set of similar principles consistent across all three categories. Based on the case study research, the assumption is made that a sequential order of implementation exists within the set of identi!ed principles. The second phase of research tests the sequential order of rendering parameters through 3d model experimentation. In this experimental process, two different building types are used as test subjects. The !rst project is a medium scale museum created by Alvaro Siza, called the Mimesis Museum. The second project is a large scale skyscraper proposed by HOK, Shanghai office. These two test subjects are modeled in the 3ds Max software application and rendered with the V-Ray plug-in application for 3ds Max. The process of experimentation results in the identi!cation of a sequential order to the principles identi!ed in the !rst phase of research. The principle rendering parameters and the veri!ed sequence are then applied to two !nal projects as a culmination of the research. Research Conclusion I The principle research !ndings identify a set of principles related to architectural renderings along with a sequential order of application. These results suggest, that through a systematic application of the discovered principles, architectural rendering representations will improve in quality. While these principles will construct a sound framework towards improved rendered images, there remains further research towards the complete development of an artistically stylized architectural image.
