  • Patent number: 8310483
    Abstract: A tinted color value is produced for a surface of an object in a computer generated scene. The surface is illuminated by a light source having a lighting color value associated with the light source. A first reflected color value is calculated for the surface. The first reflected color value is calculated based on an assumption that the surface is illuminated by white light rather than the lighting color value associated with the light source. A desaturated color value is computed using the first reflected color value. A tinted color value is computed by combining the desaturated color value with the lighting color value associated with the light source. The tinted color value is stored.

  • Patent number: 8232999
    Abstract: The surface of a body of water can be animated by deconstructing a master wave model into several layer models and then reconstructing the layer models to form an optimized wave model. A wave model is obtained, which describes the wave surfaces in a body of water. The wave model is comprised of a range of wave model frequencies over a given area. A primary layer model, secondary and tertiary layer models are constructed based on portions of the wave model frequencies. An optimized wave model is constructed by combining the primary, secondary, and tertiary layer models. A wave surface point location is determined within the given area. A wave height value is computed for the wave surface point location using the optimized wave model. The wave height value that is associated with the surface point location is stored.

  • Patent number: 8189003
    Abstract: 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.

  • Patent number: 8159490
    Abstract: 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.

  • Patent number: 8026908
    Abstract: In a video or other screen display apparatus, a surround to the actual screen is provided whose light output is variable in order to compensate for the effect of ambient (room) illumination on apparent contrast and chroma of the displayed image. The relationship between ambient light level and the surround illumination is an inverse power function. This provides the effect of making the viewer perceive that the entire room is brighter than it actually is, resulting in a desirable change in his perception of brightness. Thereby, the chromaticity of the surround is variable to allow a match to the calibrated white point of the video display. The apparatus includes an ambient light sensor whose output signal is provided to a control system driving the illuminated surround.

  • Patent number: 7937245
    Abstract: 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.

  • Patent number: 7928985
    Abstract: In computer enabled key frame animation, a method and associated system for rigging a character so as to provide a large range of motion with great fluidity of motion. The rigging uses a character body that moves along a path or freely as needed. The nodes in the body and path are not physically connected but are linked for performing a particular task. This task driven behavior of the nodes which may allow them to re-organize themselves in different re-configurations in order to perform a common duty, implies a variable geometry to the entire dynamic structure. To some regard the nodes can be said to be intelligent.

  • Patent number: 7872654
    Abstract: The present invention deforms hairs from a reference pose based on one or more of the following: magnet position and/or orientation; local reference space position (e.g., a character's head or scalp); and several profile curves and variables. In one embodiment, after an initial deformation is determined, it is refined in order to simulate collisions, control hair length, and reduce the likelihood of hairs penetrating the surface model. The deformed hairs can be rendered to create a frame. This procedure can be performed multiple times, using different inputs, to create different hair deformations. These different inputs can be generated based on interpolations of existing inputs. Frames created using these deformations can then be displayed in sequence to produce an animation. The invention can be used to animate any tubular or cylindrical structure protruding from a surface.

  • Patent number: 7859546
    Abstract: Skin-attached features are placed on a computer generated character by defining a set of placement points on at least a portion of a skin surface of the computer generated character. For each placement point, a radius is defined for the placement point. For each placement point, a density value is determined for the placement point. The density value is a sum of weighted overlaps with neighboring placement points within the radius of the placement point. The weighted overlaps are functions of the radius of the placement point. The number of placement points in the set of placement points is reduced based on the density values.

  • Patent number: 7545379
    Abstract: A computer-based animation method and system for deforming animated characters (people, animals, etc.) using a volume preserving and collision resolution process for the animation. Parts of a character are deformed by a soft mesh deformation to emulate skin deformation due to flesh and muscle movement driven by the rigid body animation along the character's joints. Resolution of the interpenetration or volume loss of deformed parts is needed for smooth and realistic animation. The present method and system enable automatic collision resolution, allowing local deformations on two intersecting parts of a character so the parts no longer interpenetrate, while preserving the volume and general shape of the two parts, e.g., the character's torso and a limb.
