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： Deformations occurring in cloth can be decomposed into two components: the in-plane and the out-of-plane deformations. Stretch and shear are in-plane deformation, and bending is out-of-plane deformation. In the method, the numerical simulation can be done in real-time, and the models fix some flaws that existed in previous real-time models, leading to conspicuous reduction of artifacts. The (|x|−C)2 in the energy function is replaced with |x−x*|2 for some constant vector x*, such that the force Jacobian becomes a constant, which obviates solving the large system of linear equations at every time step. The method uses simplified physical models for both edge-based and triangle-based systems.

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： A method for generating three-dimensional speech animation is provided using data-driven and machine learning approaches. It utilizes the most relevant part of the captured utterances for the synthesis of input phoneme sequences. If highly relevant data are missing or lacking, then it utilizes less relevant (but more abundant) data and relies more heavily on machine learning for the lip-synch generation.

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 method for graphical hairstyle generation presents an interactive technique that produces static hairstyles by generating individual hair strands of the desired shape and color, subject to the presence of gravity and collisions. A variety of hairstyles can be generated by adjusting the wisp parameters while the deformation is solved efficiently accounting for the effects of gravity and collisions. Wisps are generated employing statistical approaches. As for hair deformation, a method is used based on physical simulation concepts but is simplified to efficiently solve the static shape of hair. On top of the statistical wisp model and the deformation solver, a constraint-based styler models artificial features that oppose the natural flow of hair under gravity and hair elasticity, such as a hairpin. Our technique spans a wider range of human hairstyles than previously proposed methods, and the styles generated by this technique are pretty realistic.
