Abstract
Haniwa is a term for unglazed clay artifacts in Japan,
which were lined up on the outer surface of mounded tombs.
This work represents a practical case study of
constructing a relatively accurate digital
model of a Japanese haniwa from 360 degree scan
data of an ancient artifact via non-contact 3D laser
scanning. The goal is that this research will help the
archeologist and geologist to generate artifacts in proper
3D representation and concurrently to provide an
opportunity for attractive, accurate, informative and
interactive 3D visualization, animation and VRML on
a CD or over the Web. In our case study, we use a
discrete cloud of points scattered on a surface to
construct the function representation (FRep) of a 3D volume.
The points have been obtained with a
laser scanner. The FRep reconstruction
is based on the new implementation of the algorithm using radial basis functions.
The algorithm is implemented as
a library function for the HyperFun modeling language.
