The Research And Application Of Character Micro-expression In 3D Animation

With the development of computer technology and innovation,the 3D animation technology is gradually mature,which has been widely used in animation film market.Based on the 3D animation software technology advantages and the convenience of computer animation,commercial animation has become the main force in film market.But at the same time animation film market are requiring higher requirements in many aspects of the 3D animation,especially in the expression of character of truth and vitality into the 3D animation which is a long-term problem.Expression has become a necessary factor in shaping the character of 3D animation,and is a major way to reveal an inner world of characters.Characters in the expression of the 3D animation relates to the overall quality level and development of animation.Nature gives a lot of human emotion expression,one of the most infectious is rich and colorful facial expressions.Realistic human face is a subtle change,whether consciously or unconsciously,people do any expressions were all used to convey information,can reflect the character's psychological change.The article from the role performance of facial expression as the research object,starting from the applied research of micro expression,human psychology and behavior of the relationship of micro expression.As a 3D animation role performance from theory basis,utilizing micro expression in the 3D animation role to enhance the animation role in the performance.By analyzing human micro expression in the performing arts,law and psychology theory,the article summarizes the forming principle of micro expression,forms,and finally the effective application in the 3D animation role performance,which could provide a reference for future researchers.
