Expression of wall painting that uses virtual source of light
7 Conclusion
In this paper presented here, we performed digital color restoration of Nishi
Hongwanji's cultural properties using data stored in digital archives, such as pigment
types, granule diameters, reflection spectra and multi-band photographic images.
Using color-restored images thus obtained, we generated digital representations of
shouhekiga
in Tora-no-ma using the reflection model, taking into consideration
pigment characteristics and gilded surfaces using the gold foil reflection model.
Finally, we created a three-dimensional spatial representation. Second cases, we try to
do VR reconstruction. For the restoration of the wall painting, the wall painting that
lies scattered in all parts of the world is digitalized, a positional match is done, the
lack area was analogized and the tone was corrected. Moreover, three dimension
model is generated based on a open to the public drawing and local measurement
data, and texture mapping did the wall painting restored to three dimension model.
For expression of wall painting in addition, without assuming a complex reflection
model, the effect of the lighting can be simply achieved by using the reflection
distribution filter. Moreover, expressing the presence became possible through the
interaction with the user. One wall painting image is projected in front of the user, and
a virtual effect of the lighting has been achieved under the present situation.
