the cultural heritage contents.
1. A Case Study of Virtual Museum: Reconstruction and
Restoration of Dunhuang Caves in China
Abstract:
Some techniques we used and some experiences we had for
building a virtual Dunhuang Caves are introduced in this talk.
The main focus is on how effectively to represent and
disseminate the Caves virtually.
2. 3D Modeling Techniques for Virtual Museum Exhibition
Abstract:
3D
geometric modeling techniques are essential building blocks to
create attractive contents for a virtual museum (VM). They
precisely capture and reconstruct real objects' shapes to
visualize historically valued entities in a virtual space.
Preservation and restoration of the reconstructed objects are
also important functions to realize a usable VM. This talk
introduces some geometric modeling techniques to digitize,
visualize, and manipulate the 3D objects scanned by range
finders, and efficiently support distributed data sharing and
collaborative work in a networked VM. A scanned 3D object is
typically represented as a polygon mesh. Because the polygon
mesh is an unstructured huge dataset, it is difficult to process
such data with 3D modeling operations. We developed a method to
make the 3D modeling an easy task. It transforms a 3D polygon
mesh into a geometrically equivalent 2D gray scale image. Then
the method allows users to easily perform 3D geometric
operations such as deformations and shape blending by editing
and retouching the transformed 2D image. It also provides
various modeling operations through the use of commercially
available image processing tools. Additionally, it effectively
realizes common functions required to construct a networked VM
such as a progressive 3D data transfer to incrementally send a
huge dataset from its rough shapes to the details, an LOD (level
of detail) function to dynamically adjust 3D objects' resolution
for efficient rendering, and a 3D data compression.
3. Image Mosaic Techniques for the Restoration of Virtual
Heritage
Abstract:
In this
paper, we introduce our researches on virtual heritage contents
generation techniques.. Here, we present our contents generation
techniques based on actual measurements, using infrared camera,
X-ray camera.. Especially, we will introduce our mosaic
techniques for underdrawing of wall paintings using IR image,
old sword using X-Ray images.
