A novel method and system is disclosed to realistically simulate the progress or worsening of facial skin features that contribute to the overall look and condition of the skin. The method utilizes two close-up photographs of the face, one is captured with a digital camera in standard white light, and the other is captured with the same camera in UV light. Then, the method processes these images to simulate the progress or worsening of the major skin features: hyperpigmented spots, wrinkles and small texture features. The worsening of these features simulates facial skin aging due to prolonged exposures to sunlight, biological aging or degradation of the skin health. The progress of these features simulates the improvement of facial skin in terms of overall look and healthiness as though the patient has gone through a treatment. Therefore, the present invention discloses a series of methods that are useful in dermatology, cosmetics and computer animations.

Embodiments of the present invention provide methods and apparatus wherein physics models are integrated with motion capture animation to allow for variability in animations, dynamic response, such as animating events different from those for which motion capture data was obtained, including changes in character purpose and collisions. The physical model may include sets of internal forces and / or external forces. To facilitate the integration of mo-cap animation data with physics models, mo-cap animation data is played back using forces on physical models rather than directly setting joint angles or positions in a graphical skeleton, which allows the animation to be dynamically altered in real-time in a physically realistic manner by external forces and impulses.

Disclosed are a system and method for creating multi-angle views of an object-of-interest from images stored in a dataset. A user specifies the location of an object-of-interest. As the user virtually navigates through the locality represented by the image dataset, his current virtual position is determined. Using the user's virtual position and the location of the object-of-interest, images in the image dataset are selected and interpolated or stitched together, if necessary, to present to the user a view from his current virtual position looking toward the object-of-interest. The object-of-interest remains in the view no matter where the user virtually travels. From the same image dataset, another user can select a different object-of-interest and virtually navigate in a similar manner, with his own object-of-interest always in view. The object-of-interest also can be “virtual,” added by computer-animation techniques to the image dataset. For some image datasets, the user can virtually navigate through time as well as through space.

A multi-user animation process receives input from multiple remote clients to manipulate avatars through a modeled 3-D environment. Each user is represented by an avatar. The 3-D environment and avatar position / location data is provided to client workstations, which display a simulated environment visible to all participants. A text or speech-based bulletin board application is coupled to the animation process. The bulletin board application receives text or speech input from the multiple remote users and publishes the input in a public forum. The bulletin board application maintains multiple forums organized by topic. Access or participation to particular forums is coordinated with the animation process, such that each user may be permitted access to a forum only when the user's avatar is located within a designated room or region of the modeled 3-D environment.

Methods for defining smooth and continuous coordinate systems in a volume comprised of a lattice structure of guide columns derived from arbitrarily modeled surface topologies involving polygons, nurbs, linear segments, and subdivision surfaces. Applications of these techniques in computer graphics and computer animation include: (1) the definition of pseudo-coordinate systems for use in creating geometry which must grow from said surface (2) the creation of a highly stable coordinate system involving guide columns in which Cartesian physical simulations may be carried out and rendered as well as deformed and rerendered if desired.

Methods and systems are disclosed to realistically simulate facial wrinkle aging of a person using a neutral state (natural look) image and one or more expression images (e.g., smile, frown, pout, wink) that induce wrinkles. The neutral and expression images are processed to simulate wrinkle aging by registering the wrinkles that are visible in the expression image onto the neutral image, thereby generating a wrinkle-aged simulated image. Advantageously, a person's own wrinkle histological data is utilized, hence providing an accurate and realistic wrinkle aging simulation. Similarly, the neutral image is processed to eliminate all visible wrinkles thereby generating a wrinkle de-aged simulation image. Additionally, blending of a neutral image with an aged or de-aged simulation image is disclosed, where the degree of blending is based on statistical modeling of skin condition with age and / or expected outcome of a particular type of treatment. The methods and systems disclosed have wide applicability, including, for example, areas such as dermatology, cosmetics and computer animation, among others.

A computer software method for creating a computer animation using static and animated images is disclosed. The computer software method provides a user interface that has a first window portion and a second window portion. In the first window portion, images can be manipulated to create a frame, the frame being one of a plurality of frames which make up a computer animation. The second window portion displays the plurality of frames thus allowing previewing the computer animation. The computer software method permits a user to load at least one image into the first window portion. The at least one image in the first window portion can be edited and manipulated so as to build a scene. The user can then create a frame by capturing the contents of the first window. The computer software adds the newly created frame to the plurality of frames displayed in the second window portion. The plurality of frames is then displayed in the second window portion as an animation.

A computer-animated scene illuminated by indirect light is shaded. The scene is comprised of sample locations on a surface element of an object in the scene. A point cloud representation of the scene is generated. Optionally, an importance map of the scene, based on the point cloud representation, is generated. The importance map is generated by rasterizing one or more points in the point cloud and designating areas of interest based on the energy value of the one or more points in the point cloud. A ray tracing engine is biased, based on the importance map. The biased ray tracing engine calculates the path of the ray to the sample locations in the scene to an area of interest. The scene is shaded using the output from the biased ray tracing engine.

A computer-animated scene is shaded by a computing system having an in-core memory and coupled to one or more out-of-core storage devices. The scene is comprised of shading locations on a surface element of an object in the scene. A point cloud representation of the scene is generated. An octree data structure based on the point cloud representation of the scene is generated. To generate the octree data structure, the Morton code for each point in the point cloud representation of the scene is computed. The points are then sorted based on the Morton code, recursively subdivided to find at most a threshold number of nodes, and written to the one or more out-of-core storage devices. The shading locations are then shaded based on the nodes written to the out-of-core storage devices.

The present invention is related to rendering computer animated video and / or images generally, and to simulating motion blur efficiently in computer graphics. The present invention includes selecting a plurality of sample locations from which to sample an object scene. If a given sample location overlaps a moving object, existing sample data computed or initialized for the sample location is replicated. This data is then separately updated by sampling the moving object at a plurality of times during the object scene. The replicated data is updated further by subsequently sampling moving and non-moving objects at some or all of the plurality of times. After all of the objects that overlap the sample location have been processed, the replicated data, which may be updated, is combined.

The convex hull and OBB-based three-dimensional grid model framework extracting method has the advantages of accurate data, convenience for operating, high calculating efficiency and the like. The invention also has an important application value in fields, such as computer animation, object identifying and matching, model reconstruction, virtual navigation and the like.

A method of globally analyzing intersections between objects in computer animation includes providing objects represented by meshes, with each of the meshes being formed by a set of vertices, where a set of pairs of vertices defines a set of edges of the mesh. All edges of the meshes are checked to determine if the edges intersect with any of the meshes. An intersection path, formed by the intersection of the meshes, is traced and which vertices that are contained within the intersection path are determined. A polarity of each of the contained vertices is set to indicate that those vertices are contained within the intersection path. The analysis forms the backbone of a collision-response algorithm for unoriented objects such as cloth that is better than previous existing algorithms. The analysis also allows objects to be simulated even when hand-animated elements of the simulation have extreme amounts of interpenetration. Finally, simply displaying the nature and extent of the data found from the analysis provides extremely useful feedback to an end-user.
