| In the digital media era,the illustration art based on traditional media communication in the past is gradually blooming new vitality and artistic expression.The efficient and intelligent digital media provides a new vision and perception for digital illustration.If the traditional illustration based on paper media still has strong two-dimensional limitations and needs to compress the artistry and narration of the artist’s intention to depict to a single plane,then the digital dynamic illustration adds the concept of time to the two-dimensional illustration.Nevertheless,illustration art still takes plane display as the main way of expression.How to break through the dimension of two-dimensional media and release the unique visual experience of two-dimensional media with three-dimensional media has become an urgent problem for artists in the digital media era.Through the long-term observation and Research on the works of three-dimensional visual expression and digital illustration works,the author understands that the three-dimensional modeling technology is penetrating into people’s daily life with its unique sense of space volume and reality.The digital illustration assisted by three-dimensional technology is increasing day by day.The blending application of media promotes the further development of digital illustration and makes the emergence of digital three-dimensional illustration possible.With the rapid development of digital media art,digital three-dimensional illustration can show the spatial concept of illustration art in an intuitive visual language,cross the constraints of dimensions,add the realism of space in the illusion,reproduce the visual space in the designer’s fantasy,and form a new art form integrating three-dimensional visual form and twodimensional illustration style display.Starting from the development context of illustration,this paper summarizes the development process of illustration,digital dynamic illustration and digital three-dimensional illustration from the perspective of dimensional development,and summarizes the characteristics of digital three-dimensional illustration in the digital era-multidimensional and digital,immersive and interactive,narrative and interesting.On this basis,from multidimensional display From the perspective of interesting performance and humanized communication,this paper discusses the expression language innovation of digital threedimensional illustration,so as to explore the application and expansion of digital threedimensional illustration,and condense the application advantages and innovation direction of digital three-dimensional illustration design.The change of spatial dimension of digital illustration not only means that artists can use richer means of expression,but also means the new development and new opportunities of digital illustration.This paper explores and analyzes the application of digital 3d illustration in the fields of animation design,advertising design,game interaction design and user interface design,and summarizes its innovative advantages,so as to provide theoretical support for the development and application of digital 3d illustration.The significance of this paper is to combine the computer three-dimensional technology in the field of technology and science with the digital illustration in the field of art,which can build a digital three-dimensional illustration with new concepts.With rich creative tools and creative carriers,it can more intuitively show the art space for the viewer and provide a more vivid and interesting application display form. |
