Research On Application Of Non-Photorealistic Rendering In Design And Invention Of Digital Art

As the progress of digital technique, the relation between computer and human's life is becoming more and more closer and extends every field. The combination of computer technique and art gives birth to a newart form——digital art. During these years, digital art developed rapidlyand has become a mainstream art form that impacts the traditional art. However, as a new subject, the development of digital art is still not enough and lack of corresponding theory and judge system is its shortcoming.Non-Photorealistic Rendering is a special form in the field of digital art, which aims to achieve traditional hand-draw style by simulation. It shortens the distance between digital and art to become the best example of combination of technique and art. Moreover, it is significant for the theory study of digital art to research Non-Photorealistic Rendering that belongs to that in order to find its own art particularity.This thesis discusses leitmotiv, process and result of Non-Photorealistic Rendering from the angle of technique and art, not only the application of technique, but also the analysis of phenomena and essence. During the research process, conception, principle, method and application field are firstly analyzed and summarized, followed by the comparison between Non-Photorealistic Rendering and traditional art in invention process and visual form, which finds the differences and sameness of them. Based on the analysis of its art and technique characters, this thesis points out the main problems that Non-Photorealistic Rendering faces and describes its advantages and disadvantages and agrees with its value and reason of existence.For the further development of Non-Photorealistic Rendering, this thesis brings forward its own judgment and assumption. At the precondition of analysis about relation of Non-Photorealistic Rendering and traditional art, this thesis predicts the development trend of its polarization inevitability and advances the assumption of two development ways: technique and art. At the same time, the thesis points out that only the Non-Photorealistic Rendering breaks through representation form and theory;it can establish its station in art field. The author thinks that sculpt and representation is two parts of Non-Photorealistic Rendering's breakthrough and innovation. At last, this thesis discusses the positive significant of Non-Photorealistic Renderingfor development of digital art and analyzes that research about it is also good to further development and improvement for digital art theory, so digital art can become a real specific art form which can break away from bondage of traditional art.
