Research And Practice Of Light And Shadow On The Creation Of Animation Atmosphere

With the continuous innovation and development of animation production technology,the artistic expression of animation has also been enhanced like never before.For the animation creators,the meaning of making animation film is no longer limited to let the picture tell the story of the routine,but in the picture quality and effect of continuous exploration,in order to enrich the visual experience of the film,let the audience enjoy the visual feast has become the important goal pursued by many animation films.Among them,light and shadow have an irreplaceable role and value for the creation of animation atmosphere.The sense of light and shadow in animation is a form and means of expression that exists in the virtual three-dimensional space,based on the reference to the realistic light and shadow form,and is used to express the effect of animation picture.This expression has become a common topic of inquiry for many animation researchers.Through continuous technical innovation,the light and shadow effect in animation is not only a tool to compose the scene,but also a major expressive force in every scene of the animation film.It can not only express the creator’s creative intention,assist the development of the plot,express emotion and shape the characters,but also the gorgeous forms and fleeting changes of light and shadow provide the creator with a source of inspiration for continuous innovation.This thesis takes practical applications as a starting point,starting from the concept of "light and shadow,atmosphere",and elaborates on the concept of light and shadow,the types of light and shadow in Unreal Engine,and their effects on various aspects of animation atmosphere.The paper also focuses on the practical application and operation of light and shadow in Unreal Engine,and concludes with a comprehensive and in-depth study of the important influence of light and shadow on the animation atmosphere in the final design process.The research of this article is based on the influence of Unreal Engine’s light and shadow system on the animation atmosphere.The first chapter analyzes the significance of the selected topic,literature,current status and innovation,and presents the arguments.Chapter 2 introduces the concepts of light and shadow and animation atmosphere,as well as the features and advantages of the Unreal Engine,providing a theoretical basis for the subsequent applied research.Chapter 3 explores the aesthetic principles of light and shadow,analyzes the influence of light and shadow on atmosphere creation,and the rendering methods of light and shadow in film and animation creation.Chapter 4introduces the technical methods for creating the atmosphere of animation by light and shadow in Unreal Engine,including the setting,production and optimization of lighting,materials and shadows.Chapter 5 introduces the production background of the Unreal Engine animated short film "Return",analyzes and applies the specific process and effect of light and shadow design and application,and shows the advantages and performance of Unreal Engine in the production of the short film.
