摘要： An automatic garment grading is provided. A retargeting technique is used with the mediator and the correspondence function. The mediator is a parameterized draft. Local coordinates systems are used for making correspondence. The mean value coordinates system (MVC) are improved so that the weights would have positive values, which is omitted mean value coordinates (OMVC). The mediator is parameterized draft, and correspondence function is the OMVC in the method. Smart grading is less time-consuming and easy to implement, and can minimize designer's specialized know-how and save performing time for the grading of real garment and virtual garment.

摘要： A method for simulating the stretching and wiggling of liquids is provided. The complex phase-interface dynamics is effectively simulated by introducing the Eulerian vortex sheet method, which focuses on the vorticity at the interface and is extended to provide user control for the production of visual effects. The generated fluid flow creates complex surface details, such as thin and wiggling fluid sheets. To capture such high-frequency features efficiently, a denser grid is used for surface tracking in addition to coarser simulation grid. A filter, called the liquid-biased filter, is used to downsample the surface in the high-resolution grid into the coarse grid without unrealistic volume loss resulting from aliasing error.

摘要： The method provides a new fluid simulation technique that significantly reduces the non-physical dissipation of velocity using particles and derivative information. In solving the conventional Navier-Stokes equations, the method replace the advection part with a particle simulation. When swapping between the grid-based and particle-based simulators, the physical quantities such as the level set and velocity must be converted. A novel dissipation-suppressing conversion procedure that utilizes the derivative information stored in the particles as well as in the grid points is developed. Through several experiments, the proposed technique can reproduce the detailed movements of high-Reynolds-number fluids, such as droplets/bubbles, thin water sheets, and whirlpools. The increased accuracy in the advection, which forms the basis of the proposed technique, can also be used to produce better results in larger scale fluid simulations.

摘要： A method of simulating the movement of cloth and a computer-readable medium storing a program which executes the method of simulating the movement of cloth, wherein cloth deformation by compressive force is simulated by an immediate buckling model when the compressive force is applied to two extremities of a deformation unit which models the cloth, cloth deformation by stretching is simulated by a spring model, and hysteresis phenomenon of cloth is simulated by using spring-slips for modeling. The immediate buckling model is based on a model of the present invention in which a deformation unit is not contracted by compressive force and generates an immediate bending deformation. As for the compressive force and stretching, simulation is implemented by separate models, hysteresis phenomenon of cloth is simulated by use of spring-clips for modeling, whereby cloth characteristics can be well reflected and the buckling instability of cloth caused by compressive force can be solved, thereby increasing the simulation speed.

摘要： A new method for the identification of body landmarks from three-dimensional (3D) human body scans without human intervention is provided. The method is based on a population in whom landmarks were identified and from whom 3D geometries were obtained. An unmarked body (subject) is landmarked if there is a landmarked body in the population whose geometry is similar to that of the subject. The similarity between the surface geometry of the subject and that of each individual in the population can be determined. A search is performed using the mesh registration technique to find a part-mesh with the least registration error; the landmarks of the best-matched result are then used for the subject.

摘要： In blendshape-based facial animation, two main approaches are used to create the key expressions: manual sculpting and statistically-based techniques. Hand-generated expressions have the advantage of being intuitively recognizable, thus allowing animators to use conventional keyframe control. However, they may cover only a fraction of the expression space, resulting in large reproduction animation errors. On the other hand, statistically-based techniques produce eigenfaces that give minimal reproduction errors but are visually non-intuitive. In the invention the applicants propose a technique to convert a given set of hand-generated key expressions into another set of so-called quasi-eigen faces. The resulting expressions resemble the original hand-generated expressions, but have expression space coverages more like those of statistically generated expression bases. The effectiveness of the proposed technique is demonstrated by applying it to hand-generated expressions.
摘要翻译：在基于混合成像的面部动画中，使用两种主要方法来创建关键表达：手工雕刻和基于统计的技术。手工生成的表达式具有直观可识别的优点，因此允许动画师使用传统的关键帧控制。然而，它们可能仅覆盖表达空间的一部分，导致大的再现动画错误。另一方面，基于统计学的技术产生了特征面，其产生最小的再现误差，但在视觉上不直观。在本发明中，申请人提出了一种将给定的手生成的关键词表达式转换成另一组所谓的准本征面的技术。得到的表达式类似于原始的手工生成的表达式，但是具有更多与表达式基础相似的表达式空间。所提出的技术的有效性通过将其应用于手工生成的表达来证明。
