20090018803 | METHOD OF CLOTH SIMULATION USING LINEAR STRETCH/SHEAR MODEL - 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.

20100057455 | Method and System for 3D Lip-Synch Generation with Data-Faithful Machine Learning - 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. | 03-04-2010 |
20100215235 | METHOD FOR POPULATION-DRIVEN IDENTIFICATION OF BODY LANDMARKS - 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. | 08-26-2010 |
20100250213 | SEMI-LAGRANGIAN CIP FLUID SOLVER WITHOUT DIMENSIONAL SPLITTING - A new constrained interpolation profile method, which is stable and accurate but requires less amount of computation, is provided. CIP is a high-order fluid advection solver that can reproduce rich details of fluids. It has third-order accuracy but its computation is performed over a compact stencil. A novel modification of the original CIP method that fixes all of the above problems without increasing the computational load or reducing the accuracy is provided. The proposed method brings significant improvements in both accuracy and speed. | 09-30-2010 |
20110112800 | Method for Simulating Stretching and Wiggling Liquids - 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. | 05-12-2011 |
20120143573 | Method for Tracking Detail-Preserving Fully-Eulerian Interface - A method for tracking fully-Eulerian interface is provided, which preserves the fine details of liquids. Unlike existing Eulerian methods, the method shows good mass conservation even though it does not employ conventional Lagrangian elements. In addition, it handles complex merging and splitting of interfaces robustly due to the implicit representation. To model the interface more accurately, a high order polynomial reconstruction of the signed distance function is utilized based on a number of sub-grid quadrature points. By combining this accurate polynomial representation with a high-order re-initialization method, the method preserves the detailed structures of the interface. Moreover, the method is simple to implement, unconditionally stable, and is suitable for parallel computing environments. | 06-07-2012 |
20150242545 | Method of Simulation of Moving Interfaces using Geometry-Aware Volume of Fluid Method - A method for simulating moving interface in viscous incompressible two phase flows is provided by conservation of the fluid volume and a detailed reconstruction of the fluid surface using sub-grid refinement of the level set with the volume-of-fluid method. | 08-27-2015 |
20150242546 | Method of Cloth Simulation using Constrainable Multigrid - A method of cloth simulation using a constrainable multigrid is provided. The method includes steps of: calculating a change of geometry of the mesh of nodes at a plurality of time steps using a multigrid method by solving a time-varying partial differential equation at multiple resolutions or levels; providing a hierarchical mesh through restriction or coarsening by down-sampling from level m to m−1 or prolongation or interpolation by up-sampling from level m to m+1; transferring soft constraints between different hierarchical levels using a damper-based constraint method; updating the position vector x and the velocity vector v of the mesh nodes; and displaying an updated state of the mesh of nodes using updated position vector x and velocity vector v on a display. | 08-27-2015 |
20150243076 | METHOD OF SMART GRADING BASED ON PARAMETERIZED DRAFT - 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. | 08-27-2015 |
