2) processor is made a plurality of expression objective body models according to actor model information, and it is carried out the transfer of expression objective body process;
3) processor carries out the Blendshape deformation process to actor model and expression objective body model, obtains new actor model;
4) processor carries out the textured bone processing to new actor model, obtains binding actor model;
5) processor carries out the Cluster deformation process to the binding actor model, obtains complete expression control role model;
Send to video card after the complete expression control role model information that 6) will obtain, the video driver display carries out role's demonstration of expressing one's feelings.
Described Blendshape deformation process may further comprise the steps:
A) the former actor model A of multiple copies obtains actor model B, actor model C, actor model D
B) revise actor model B, actor model C and actor model D, be respectively the expression model that the role makes to be needed, namely revise the point of actor model B for laughing at expression, the point of revising actor model C is the expression of crying, the point of the modification actor model D gas meter feelings of making a living.
C) actor model B, actor model C, actor model D are added to the Blendshape objective body of former actor model A;
D) revise Blendshape objective body parameter, the new role model after obtaining being out of shape.
Described textured bone is processed and be may further comprise the steps:
A) based on the facial positions of actor model A, place corresponding bone B.
B) with actor model A covering to bone B.
C) the weight message bit pattern of drafting actor model A.
D) mobile bone B, thereby the expression of driving actor model A.
Described Cluster deformation process may further comprise the steps:
A) based on the facial positions of actor model A, choose the point on the corresponding model, set up Cluster;
B) repeat a) to set up a plurality of Cluster;
C) move one or more Cluster, thereby drive the expression of actor model A.
Compared with prior art, the present invention has the following advantages:
1) this control system modular construction is clear, and each functions of modules is clear and definite;
2) kit that provides is with strong points, and make efficiency is high;
3) adopt Python and QT to write, have the self-defined property of height, user friendly self-defined and expansion;
4) (QT and Python are cross-platform instruments to have very strong transplantability, can be transplanted to easily the other system platforms such as Linux), native system has the core algorithm of oneself on the other hand, can be transplanted to easily other three-dimensional software platforms such as 3dMax and houdini;
5) native system adopts the software and hardware hybrid algorithm to realize, operation efficiency is provided.
