3 The Mixed-Method Approach for Rapid Modeling

A mixed-method combining three different approaches is adopted regarding to differ-
ent complexity levels to make the design process more efficient realistic. The follow-
ing part will introduce the three modeling approaches by the reconstruction of the
Qiao's Grand Courtyard.

3.1 3D Modeling Based on Modeling Software

The powerful software 3DS MAX is used for reconstruction of majority of artifacts in
a virtual scene. The key technology in this process [6] is to optimize the models and
scene, including reduction the model and face without bringing down the realistic
