In order for a given geometric configuration to be realized through digital fabrication, a detailed geometry is required. A system of elements can then be obtained from based on the detailed geometry that is provided. Also, the digital fabrication process can be integrated with the iterative design process and the elements required may grow exponentially. This is as a result of the fact that as the design process advances, more geometric configurations are added and this add some details to the given surface. The description of the NURBS surface is defined systematically to create a supporting framework of ribs.
Programming techniques can then be used to extract the geometric information that is contained within each NURBS surface. This is the final information that is used to generate templates that are used in the digital fabrication process (Piegl and Tiller, p. 48). It should be noted that digital fabrication has played an important role in redefining the traditional architectural design process. Through the adoption of digital design principles, a designer can closely integrate the design process and the physical representations that are obtained.
This makes it possible for the material qualities to be tied to the design process. Traditionally, the fabrication process was essentially a hand and tool job that could only take place after the design process. However, digital fabrication makes it possible for the design process to be iterative. This is because the architect or designer can be able to test the designs in a piecemeal and progressive manner. Therefore, digital fabrication makes the design process to be closely tied to the material properties. The final outcome is also much more likely to lie within the set parameters of the designer and limit costs and the chances of waste.
The Beijing National Stadium which is universally known as the “ Bird’ s Nest” was built as the primary site for the twenty-fourth Olympiad that was held in Beijing in August 2008. The stadium was built to act as a practical venue of the Olympics and also as an icon in architecture.
