Problems solved by technology

Such a method can have a fixed animation control module, but due to format differences, the face model may lose some information after format conversion, such as light and shadow effects, etc.
On the other hand, there may already be a mature display method for a certain format, such as scene selection, the display results after format conversion may not be able to achieve satisfactory results

Embodiment Construction

[0022] Because the face animation definition table has a great correlation with the face model, in order to make the face animation control method of the present invention be applied to face models of different formats, the present invention proposes a layered process of display and control Methods. Firstly, a corresponding simple face model and vertex serial number correspondence table is generated from a face model in a special format, and then the face animation definition table of the simple face model is constructed. After obtaining the animation data, the control layer searches the face animation definition table To generate animation, and then convert the deformed face model into the original special format through the vertex serial number correspondence table, and finally display it. The present invention is based on the MPEG-4 standard, and realizes the animation control of a standard simple face model by constructing a face animation definition table. The simple face...

Abstract

The invention is a cartoon realizing method of face model in any type which is based on MEPG-4, it includes: the display layer and the control layer process the display and cartoon control respectively; for the face model of particular format, it generates the corresponding face model and the peak number correspondence table; works out the face cartoon definition table of the simple face model on base of standard face cartoon definition table; the control layer change the simple face model through searching the face cartoon definition table of simple one, then changes the reformed face model into the one of particular format according to the peak number correspondence table; dislays the face model of particular format.

Description

technical field [0001] The present invention relates to a kind of animation realization method based on MPEG-4 arbitrary format human face model, especially a kind of display and control is divided into two layers of processing, between the two layers with the vertex sequence number corresponding table to carry out data conversion, in the control The layer realizes the animation control method by constructing the face animation definition table (FaceDefTables). Background technique [0002] Computer 3D facial animation is an important human behavior interaction method. Its results can be applied to many fields such as virtual reality, virtual host, virtual meeting, auxiliary teaching, medical research, film production, game entertainment, etc. With the rapid development of computer hardware, network and multimedia technology, 3D facial animation will inevitably be more and more widely used in the future human-computer interaction interface. [0003] MPEG-4 is an object-bas...
