Abstract: A method of skin microstructure texture filtering for facial animation includes obtaining a plurality of one-dimensional (1D) filtered tiles corresponding to a plurality of filter axis angles and a plurality of filter parameters applied to a neutral tile, and at runtime, for each pixel representing a region of human skin, determining a principal direction of deformation, a principal filter parameter corresponding to the principal direction of deformation, and a secondary filter parameter corresponding to a secondary direction of deformation orthogonal to the principal direction of deformation, and selecting a first 1D filtered tile among the plurality of 1D filtered tiles, the first 1D filter tile corresponding to the secondary direction of deformation and the secondary filter parameter, and generating a respective two-dimensional (2D) filtered tile by convolving the first 1D filtered tile with a second 1D filter kernel corresponding to the principal direction of deformation and the principal filter parameter

Abstract: The present disclosure provides embodiments of systems and methods for rendering and skinning in video game applications that utilize a modified finite elements analysis in combination with position based dynamics. Position based dynamics can be used to provide a tradeoff of accuracy for speed and stability. The resulting position based finite element process provides for rendering and skinning elements, such as character models, during real time execution of a game application. Embodiments of the position based finite element technique can provide high quality deformations with a small number of elements, and simulate those elements more efficiently than previous methods used in the art.
