Embodiments relate to a computer-implemented method of providing a transition between first and second regions within a virtual scene, where the first and second regions are rendered using different methods and being connected to one another along a border line. The second region features a sharply diminishing illumination from the border line. The method includes adding, an overlay of additional illumination to the first region as to make the illumination in portions of the first region that are close to the borderline similar to that of portions of the second region that are close to the border line. The method also includes shifting a position on which calculation of the illumination of the second region is based away from the first region.

Transitioning between shading regions on an object

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.
