Abstract
In hand-drawn illustrations, we often draw pictures with various thickness lines. And in some animations, lines which construct an image change their thicknesses according to the view direction. However, these features cannot be captured with traditional rendering methods. For solving these problems, we propose a view-dependent line rendering method. That is, after creating 3D data objects, a user sets each line thickness information according to the view direction. Then, it is stored to a user-defined reference table named line rendering information table. By using this method, a user can set the line rendering thickness freely in one object and can control thickness of each line according to the view direction.
