The key Techniques Study of Constructing the Roaming Modelin Virtual Environment

Abstract

Taking the digitization of Zhengzhou University campus as an example, the 3-D
model of every buildings of Zhengzhou University were constructed with VR technology and 3D
image processing technology. The paper has studied the questions that need to be solved in the
construction process of digitizing campus and in the model roaming process, this solution has
been successfully used in the scientific research item of digitizing Zhengzhou University. The
study results can be summarized as follows：(1) the Texture Mapping Technology make the 3D
model roaming more smoother; (2) the Construction Technologies of many trees models make the
data volume worse; (3) the 3D digitization of Zhengzhou University campus provides a new idea
to construct 3D virtual large scene model.
