    During the past decade, researchers have developed several techniques for transplanting motions. These techniques transplant a partial auxiliary motion, possibly defined for a small set of degrees of freedom, on a base motion. Motion transplantation improves motion databases' expressiveness and allows more control in interactive applications by letting users synthesize body parts separately. Howev... View full abstract»

    Desktop grids combine arbitrary computational resources connected to a network. However, the prevalent interactive rendering algorithms can't seamlessly handle the variable computational power offered by a desktop grid's nondedicated resources. In this article, a method for achieving interactive high-fidelity rendering on nondedicated machines such as desktop grids is developed, without the expens... View full abstract»

    Nonrigid deformation is a fundamental feature in face recognition. The proposed method extracts nonrigid deformation by finding the mapping between two shapes. To improve registration accuracy, it integrates geometric shape decomposition and nonrigid point-set registration. On the basis of manifold harmonics, the method first decomposes shapes into low-frequency and high-frequency parts. Then, it ... View full abstract»

    OCME (Out-of-Core Mesh Editing) comprises a novel data structure and related algorithms for out-of-core editing of large meshes. Triangles are inserted in a multigrid on the basis of their size in average constant time. OCME maintains no explicit hierarchy, so inserting, modifying, or deleting data doesn't require costly refitting. View full abstract»

    Sketch-n-Stretch lets novices quickly and easily create 2D animations. The system has a seamless two-layer drawing interface that supports cutouts using a whiteboard metaphor. Cutout animations serve as building blocks to help users construct sophisticated animations. While manipulating cutout animations, users can draw and write text to create effects-such as articulated figures, multiple motions... View full abstract»

    Unorganized point clouds obtained from 3D shape acquisition devices usually present noise, outliers, and nonuniformities. The proposed framework consolidates unorganized points through an iterative procedure of interlaced downsampling and upsampling. Selection operations remove outliers while preserving geometric details. The framework improves the uniformity of points by moving the downsampled pa... View full abstract»

    In computer graphics and geometric modeling, changing the variables is a useful technique that appears in many guises. It lets us change how we traverse curves or surfaces, modify their derivatives or place, and interpret textures or other properties associated with them. It is shown that while changing variables of a parametric curve or surface leaves its geometric shape untouched, changing the w... View full abstract»
