    摘要: Gradient domain editing of animated meshes is described. Exemplary systems edit deforming mesh sequences by applying Laplacian mesh editing techniques in the spacetime domain. A user selects relevant frames or handles to edit and the edits are propagated to the entire sequence. For example, if the mesh depicts an animated figure, then user-modifications to position of limbs, head, torso, etc., in one frame are propagated to the entire sequence. In advanced editing modes, a user can reposition footprints over new terrain and the system automatically conforms the walking figure to the new footprints. A user-sketched curve can automatically provide a new motion path. Movements of one animated figure can be transferred to a different figure. Caricature and cartoon special effects are available. The user can also select spacetime morphing to smoothly change the shape and motion of one animated figure into another over a short interval.

    摘要: A graphics system allows for manipulation of a detail mesh for a subdivision surface. To deform the subdivision surface, the graphics system generates a corresponding deformed control mesh by attempting to satisfy both position constraints of the manipulation and Laplacian constraints for the detail mesh. After the deformed control mesh is generated, the deformed detail mesh can be generated by applying a subdivision function to the deformed control mesh to generate a deformed smooth mesh and then applying detail information to the deformed smooth mesh.

    摘要: A method and system is provided for deforming a shape of an image. In one example, an input is received for deforming a displayed shape, the shape including a boundary polygon or outline contour and a local area within the outline contour. The local area may further include vertices and edges. During deformation, an energy function corresponding to the outline contour and the local area may be determined and reduced or minimized. Positioning of the vertices and lengths of the edges may be determined based on the energy function or preservation of coordinates associated with the outline contour and the local area.

    摘要: A real-time algorithm for rendering of an inhomogeneous scattering media such as smoke under dynamic low-frequency environment lighting is described. An input media animation is represented as a sequence of density fields, each of which is decomposed into a weighted sum of a set of radial basis functions (RBFs) and an optional residual field. Source radiances from single and optionally multiple scattering are directly computed at only the RBF centers and then approximated at other points in the volume using an RBF-based interpolation. Unique approximation techniques are introduced in the computational algorithms to simplify and speed up the computation of source radiance contributed by single and multiple scattering. Using the computed source radiances, a ray marching technique using slice-based integration of radiance along each viewing ray may be performed to render the final image.

    摘要: A system is described for using a texture synthesis approach to produce digital images that simulate motion. The system operates by receiving a large-scale motion image that describes large-scale motion, as well as one or more exemplar images that describes small-scale motion. The system then applies a texture synthesis approach to duplicate the small-scale motion described in the exemplar image(s), as guided by the large-scale motion described in the large-scale motion image. This operation produces a synthesized motion image. The system then combines the synthesized motion image with the large-scale motion image to produce a combined motion image. The combined motion image presents the large-scale motion as modulated by the small-scale motion. The system can also take account for one or more application-specific constraints, such as incompressibility and boundary conditions.
