Shading-Based Surface Modeling and Editing
We present a system for free-form surface modeling and editing that allows a user to create a surface and modify a shape by shaded image using stroke-based drawing tools. After user input sketch contours,smooth distance fields are computed,then translated into height fields. A closed smooth surface is created by the contours and the inferred height fields. Further,user can editing surface by sketched stroke,a new shape,whose rendered image closely approximate user input,is computed using an efficient and stable surface optimization procedure. We demonstrate how several types of free-form surface modeling and editing which may be difficult in terms of standard modeling and deformation approaches can be easily performed using our system.
