Research On Non-photorealistic Mapping Design Of 3D Animation Under The Influence Of Texture Mapping Technology

Under the influence of factors such as the rapid development of digital technology and the diversified aesthetic needs of the audience,there are a large number of stylized works in 3D animation,which simulate the hand-painted effect of 3D scene,character contour and texture mapping,so as to achieve the purpose of non photorealistic design.At present,the non photorealistic design of 3D animation in the industry is mainly realized by digital hand drawing,stylized plug-in conversion,program material node control and other methods.Its low work efficiency and high technical threshold seriously affect the realization of non photorealistic effect.Through the research on the mapping method,this paper proposes to combine texture mapping with digital hand-painted technology,map the hand-painted map on the basis of texture mapping,and present the effect of non photorealistic rendering.In the mapping design,the model UV coordinates,program mapping and hand-painted mapping technology are combined to improve the accuracy of texture mapping in 3D scene and character mesh model.Finally,through the optimization of animation lights,the non photorealistic animation rendering effect of hand-painted style is realized,and the production efficiency is improved.
