    摘要: Provided is a method of simulating various viscoelastic fluids having viscosity, elasticity, and plasticity, based on smoothed particle hydrodynamics (SPH), which is widely used in fluid simulation using particles. Artificial forces related with viscosity, elasticity, and plasticity are added to address fundamental numerical limitations of a SPH method due to use of particle approximation and to improve expression of characterized motions of a viscoelastic fluid. Since the artificial forces are added, and parameters are adjusted according to the adding of the artificial forces, a fluid can be realistically expressed, and the control of a fluid motion is facilitated.

    摘要: Disclosed herein is a method and system for transforming the muscles of a character model. The muscles of a target model are created using the muscle information of a reference model. The system includes a reference model processor and a target model processor. The reference model processor creates a reference feature volume, that is, a 3D geometric shape, based on the skeleton and appearance information of the reference model, and subordinates the muscle information of the reference model to the feature volume. The target model processor deforms the reference feature volume to be suitable for the target model, and applies the muscle information of the reference model to the target model, thereby creating muscles for the target model based on the extent of the deformation of the reference feature volume.

    摘要: The present invention relates to a method of creating an animatable digital clone includes receiving input multi-view images of an actor captured by at least two cameras and reconstructing a three-dimensional appearance therefrom, accepting shape information selectively based on a probability of photo-consistency in the input multi-view images obtained from the reconstruction and transferring a mesh topology of a reference human body model onto a shape of the actor obtained from the reconstruction. The method further includes generating an initial human body model of the actor via transfer of the mesh topology utilizing sectional shape information of the actor's joints, and generating a genuine human body model of the actor from learning genuine behavioral characteristics of the actor by applying the initial human body model to multi-view posture learning images where performance of a predefined motion by the actor is recorded.
