GRAPHICS SYSTEM WITH STITCHING HARDWARE SUPPORT OF SKELETAL ANIMATION

摘要

PROBLEM TO BE SOLVED: To obtain a graphics chip (graphics device) having a hardware support for stitching. SOLUTION: The graphics system includes a graphics/audio processor. An additional matrix multiplication calculation nit cascaded to a model view (model view) matrix calculation unit supports a linear (piecewise linear) object, i.e., (stitching) of skinning (skinning) in a one-way in regard to a skeletal animation. A normalizing device connected between cascaded matrix multiplication calculation units provides normalization for avoiding distorted visualization. The additional matrix multiplication calculation unit can be used for an application (e.g. environment mapping) other than a skeleton animation model.
