Patent number: 8730239Abstract: 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.Type: GrantFiled: March 12, 2012Date of Patent: May 20, 2014Assignee: DreamWorks Animation LLCInventors: Bruce Nunzio Tartaglia, Doug Cooper, Pablo Valle, Michael McNeill

Patent number: 8189003Abstract: Embodiments of the present invention are directed to rendering computer graphics using an augmented direct light model which approximates the effect of indirect light in shadows. More specifically, a shadow illuminator light source is provided for. The shadow illuminator light source is associated with an ordinary, or primary light source and is used to provide illumination in areas which are in shadows with respect to the primary light source. The shadow illuminator provides illumination only to areas which are considered to be in the shadows with respect to the light source the shadow illuminator is associated with. Thus, the shadow illuminator may be used to approximate the effects of indirect light.Type: GrantFiled: May 8, 2007Date of Patent: May 29, 2012Assignee: Dreamworks Animation LLCInventors: Bruce Nunzio Tartaglia, Philippe Denis

Patent number: 8159490Abstract: 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.Type: GrantFiled: October 16, 2007Date of Patent: April 17, 2012Assignee: Dreamworks Animation LLCInventors: Bruce Nunzio Tartaglia, Doug Cooper, Pablo Valle, Michael McNeill

Patent number: 7937245Abstract: Embodiments are directed to modifying an existing scheme for providing translucent illumination in order to take account of subsurface scattering. The color of a selected point of a translucent object can be determined using existing methods. The existing methods need not take subsurface scattering into account. Then, a contribution to the color at the selected point due to subsurface scattering may be calculated. The contribution due to subsurface scattering may be calculated based on a photon map. Embodiments of the invention also include the use of different types of photon maps. In some embodiments, a standard photon map may be used. In other embodiments, a photon map may be defined in a manner similar to a depth map. Thus, the entries of a photon map may be defined in terms of an angle from a light source and a distance between an object's surface and a light source.Type: GrantFiled: April 2, 2008Date of Patent: May 3, 2011Assignee: Dreamworks Animation LLCInventors: Bruce Nunzio Tartaglia, Alexander P. Powell
