Interactive shadowing for 2D Anime
In this paper, we propose all instant shadow generation technique for 2D animation, especially Japanese Anime. In traditional 2D Anime production, the entire animation including shadows is drawn by hand so that it takes long time to complete. Shadows play all important role in the creation of symbolic visual effects. However shadows are not always drawn due to time constraints and lack of animators especially When the production schedule is tight. To solve this problem, We develop all easy shadowing approach that enables animators to easily create a layer of shadow and its animation based on the character's shapes. Our approach is both instant and intuitive. The only inputs required tire character or object shapes in input animation sequence With alpha value generally used in the Anime production pipeline. First, shadows are automatically rendered on a virtual plane by using a Shadow Map(1) based oil these inputs. Then the rendered shadows call be edited by simple operations and simplified by the Gaussian Filter. Several special effects such as blurring call be applied to the rendered shadow at the same time. Compared to existing approaches, ours is more efficient and effective to handle automatic shadowing in real-time. Copyright (C) 2009 John Wiley & Sons, Ltd.
