CA 2640108

Embodiments of the invention relate for rendering translucent objects. According to some embodiments, the color of a pixel of a translucent object that is not directly illuminated by a light source can be determined by decaying the illumination contributed by the light source according to a predefined decay function. The decay function may be, for example, an exponential decay function. The decay function may be evaluated based on an initial illumination contributed by the light source, and a transmittance distance. In some embodiments, the initial color of the pixel is decayed instead of the illumination. Also disclosed is modifying the renderings of different regions of an object which have been rendered using different methods in order to remove sharp contrasts between these regions.
