Expression generation method for three-dimensional cartoon character based on element expression

Abstract

The invention discloses an expression generation method for a three-dimensional cartoon character based on element expression. The expression generation method for the three-dimensional cartoon character based on the element expression includes that step 1, confirming several kinds of element expressions for expressing emotions according to three-dimensional cartoon manufacturing features and a modern sentiment theory; step 2, building an expression model for each element expression with the maximum degree, and separately building an expression model without expression; step 3, decomposing more than one element expression of a complex expression to be expressed, confirming the degree value thereof, and using the degree value as weight to mix with each element expression to obtain an expression model of the complex expression; step 4, setting a key frame animation with the element expression degree to obtain the expression animation. The expression generation method for the three-dimensional cartoon character based on the element expression is capable of quickly and consistently generating the character expression animation, and the character expression animation can be reused among different characters.

Description

Technical field [0001] The invention belongs to the field of three-dimensional animation, and in particular is a method for generating expression animation of a three-dimensional animation character, and is used to provide a method for quickly generating a three-dimensional character expression animation by using a meta-expression drive. Background technique [0002] Three-dimensional animation technology is an emerging technology that has emerged with the development of computer software and hardware technologies in recent years. It can easily and quickly produce three-dimensional animation or film and television special effects shots that meet the needs of directors. [0003] The production principle of 3D cartoons is generally: First, use 3D software (such as 3ds Max, Maya or Houdini) to create a virtual world in the computer; then, add scenes and 3D cartoon characters to this virtual 3D world. ; Finally, set the animation curve of the model, the motion trajectory of the virtual...

Problems solved by technology

[0011] In view of this, the present invention provides a method for generating expression animation of a meta-expression-based three-dimensional animation character, which does not directly drive the deformation of the facial model through the fusion deformer method or the bone binding animation method to combine the required Instead, the basic meta-expressions are combined based on the emotions of the characters, thus effectively overcoming the time-consuming and technically difficult shortcomings of the existing expression animation production methods, so that the expression animations produced by different animators are close to the same, and can be used for Different characters provide expression animations with roughly the same emotional meaning
