SYSTEM FOR RENDERING REALISTIC FACIAL EXPRESSIONS OF THREE DIMENSION CHARACTER USING GENERAL PURPOSE GRAPHIC PROCESSING UNIT AND METHOD FOR PROCESSING THEREOF

摘要

The present invention relates to a system for rendering a 3D character using a general purpose graphic processing unit (GPGPU) and a processing method thereof. The system for rendering a 3D character renders a 3D character model, such as skin of a multilayered structure like a human face, so that realistic skin expressions are enabled according to reflection and dispersion of light for the skin of the multilayered structure using the GPGPU. To this end, the system for rendering a 3D character has a plurality of GPGPU modules to correspond to rendering paths. According to the present invention, without passing through the rendering paths of a rendering library, an image for each layer of the skin is processed using the GPGPU to generate brightness texture, thus reducing the load on the system for rendering a 3D character. This can allow for real-time realistic skin expressions.
