Abstract
We present a rapid rendering procedure to reproduce the appearance of an
object that includes translucent material. The conventional method of rendering
the translucence of an object is difficult to implement in real time, since
the translucency is accompanied by complicated light behavior such as scattering
and absorption. To simplify this rendering process, we focus on the contrast-reversing
stimulant property in vision science. This property is based on the perception
that we can recognize a luminance histogram compatible between scattering
and absorption. According to this property, we propose a simple rendering
method to reverse the light path between reflection and transmission. Our
method adopts an additional function for selecting a front or back scattering
process in the calculation of each pixel value. Because this improvement
makes only slight alterations in the conventional reflection model, it
can reproduce a translucent appearance in real time while inheriting the
advantages of various reflection models.
