Abstract
We present a rapid rendering procedure to reproduce the appearance of an object that includes translucent material. The convention- al 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 compati- ble 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.
