Abstract. Virtual scene building is regarded as a significant part in cultural her-
itage digital presentation processes. Geometric modeling method, which has
been widely used in virtual scene reconstructing, requires lots of manual opera-
tions and a long modeling period. This article proposed an approach combining
three modeling methods to reconstruct 3D models. Various methods should be
adopted regarding to different complexity levels of objects to make the design
process more efficient and realistic. In this article, the proposed strategy will be
illustrated by presenting a virtual scene of Qiao's Grand Courtyard, one of the
most famous ancient residential building groups in Shanxi province. As a result,
a simple, efficient, cost-effective and high standard modeling approach has
been obtained for the historic heritage digital presentation.
Keywords: Virtual Scene Building, 3D reconstruction, Virtual roaming.
1 Introduction
Possessing a long civilized history, China contributes a precious cultural wealth for
the world. Some of these cultural heritages are stored in museums, while others are
handed down from generation to generation and rooted in the spirit and blood of Chi-
nese people. With the development of human civilization and technology, digital
technology provides a new way in cultural heritage preservation, and the issue
of digital preservation of cultural heritage has become an important topic in
cross-disciplinary fields, in which digitization of cultural heritage plays a significant
role [1].
Virtual scene building, as an application of VR, is an important step in digital dis-
play design of cultural heritage [2, 3]. On one hand, the realistic sensation and real-
time natural interaction depend on the improvement of the performance of graphic
workstation and implications such as digital helmets, data gloves etc. On the other
hand, it is more important to focus on the continuous improvement of construction
and display techniques in virtual scene and natural interaction. Realistic rendering for
each model's structure, function and detail is the essential requirement of an interac-
tive virtual display project.
