要旨:
Translucent objects are characterized by diffuse light scattering
beneath the object's surface. Light enters and leaves an object at
possibly distinct surface locations. This paper presents the first
method to acquire this transport behavior for arbitrary
inhomogeneous objects. Individual surface points are illuminated in
our DISCO measurement facility and the object's impulse response is
recorded with a high-dynamic range video camera. The acquired data
is resampled into a hierarchical model of the object's light
scattering properties. Missing values are consistently interpolated
resulting in measurement-based, complete and accurate
representations of real translucent objects which can be rendered
with various algorithms.
