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.

Skin microstructure texture filtering for runtime facial animations

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.
