| Abstract: |
Clip art is a simplified illustration form consisting of layered filled polygons or closed curves used to convey 3D shape information in a 2D vector graphics format. This paper focuses on the problem of direct conversion of smooth surfaces, ranging from the free-form shapes of art and design to the mathematical structures of geometry and topology, into a clip art form suitable for illustration use in books, papers, and presentations. We show how to represent silhouette, shadow, gleam, and other surface feature curves as the intersection of implicit surfaces and derive equations for their efficient interrogation via particle chains. We further describe how to sort, orient, identify, and fill the closed regions that overlay to form clip art. We demonstrate the results with numerous renderings used to illustrate the paper itself.
