Problems solved by technology

[0002] In 3D film and television animation projects, expression control has always been a very important link, which determines the quality and efficiency of animation. At present, blendshape deformation is generally used to make expression bodies, and then the secondary control is added by adding cluster control, so that The production method is relatively cumbersome and consumes the production time of the production staff

Embodiment

[0036] Such as figure 1 , figure 2 As shown, a character expression information control method for three-dimensional animation production, comprising the following steps:

[0037] 1) The processor 1 takes out the prepared character model information from the hard disk 2 and puts it into the memory 3;

[0038] 2) Processor 1 makes a plurality of expression target body models according to the role model information, and executes expression target body transfer processing;

[0039] 3) Processor 1 performs Blendshape deformation processing on the character model and the expression target body model to obtain a new character model;

[0040] 4) Processor 1 performs bone deformation processing on the new character model, and this process is jointly bound and executed by multiple sets of bones to obtain the bound character model;

[0041] 5) Processor 1 performs cluster deformation processing on the bound character model, that is, adds multiple cluster controllers to the bound cha...

Abstract

The invention relates to a method for controlling role expression information for three-dimensional animation production. The method includes the following steps that a processor fetches information of produced role models from a hard disk, and the information is placed in an internal storage; the processor produces a plurality of expression target body models according to the information of the role models and conducts expression target body transit processing on the expression target body models; the processor conducts Blendshape processing on the role models and the expression target body models to acquire new role models; the processor conducts bone deformation processing on the new role models to acquire binding role models; the processor conducts Cluster deformation processing on the binding role models to acquire complete expression control role models; the acquired complete expression control role model information is sent to a display card, and the display card drives a displayer to display role expressions. Compared with the prior art, the method has the advantages of being high in producing efficiency and portability.

Description

technical field [0001] The invention relates to a technology related to 3D animation production, in particular to a method for controlling character expression information used in 3D animation production. Background technique [0002] In 3D film and television animation projects, expression control has always been a very important link, which determines the quality and efficiency of animation. At present, blendshape deformation is generally used to make expression bodies, and then the secondary control is added by adding cluster control, so that The production method is relatively cumbersome and consumes the production time of the production staff. Contents of the invention [0003] The object of the present invention is to provide a character expression information control method for three-dimensional animation production with high production efficiency and strong transplantability in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of...
