3. Parametric modelingParametric is a “set of equations that express a set of quantities as explicit functions of a number of independ-ent variables, known as “parameters”. Therefore Parametric modeling is the model of parameters (variable). It is not the model which set and analyze by mathematic, and changing some parametric values simply in modeling to build a new one.Parameters could be geometrical parameter and some attribute parameter such like temperature and materi-als as well.Nowadays, the application of parametric modeling is in wide range more and more. Although the developing time is so short, the speed is so breathtaking. Boldly to say, it is time to change design. This is the evolution of design which base on the technical restoration. In my opinion, present design envi-ronment under the current society condition is very complex, fickle and rapid. Parametric modeling quite suits it and this is the demand of this age and technical characteristics. Therefore, parametric modeling is the certain result which could optimize society resources and increase production efficiency. Parametric modeling could apply complex and organic forms commodiously, this is no easy without any parametric design. Moreover, it could create plenty of selections efficiently. Because if you have designed out parametric modeling, the time that create 10 project selections mostly equals to the time that create 100 pro-ject selections. Architects do not need to waste time to care about if the project is as one likes, the only thing they need to care is the parametric relation between input and output.

Guangzhou Opera House was deign by architect Zaha Hadid. It is locates in Haixinsha Square, a brand new stretch of south China’s ever-expanding trading city. Opera house looks like two enormous pebbles that might have been washed up on the shore of the Pearl river. Zaha Hadid is good at buildings that shoot across the urban landscape like bolts of lighting. You can get best experiences at night. Rough-shaped things sheathed in triangles of granite and glass protrusions, one houses the main auditorium while the smaller encloses a multipurpose performance space. It is easily to identified that this absolutely a parametric project. The exposed frame which likes a giant spider web protruding in several unlikely directions. Shapes of struc-tures and spaces within them quite likes a river. Two enormous pebbles are not geometry design as well, the roof and curtain wall grouped into a integrated structure.

7th Strawberry Symposium Exhibition Center + Hotel was design by DADA Architecture by parametric design. Appearance was assembled by 10 different kinds of panels directly, this is one of few projects which using parametric modeling to decrease project cost. Architect uses a series of white curved shell-shape panels to pack the “box”. The scale of openings on panel were controls by parameter. Row upon row of windows were the achievement of parametric modeling as well.
