Abstract:
Researchers in nonphotorealistic rendering (NPR) have
investigated a variety of techniques to simulate the styles of
artists. Recent work has resulted in methods for pen-and-ink
illustration, pencil sketching, watercolor, engraving, and
silhouette edge rendering. This paper presents real-time methods
to emulate cartoon styles. We also present variations on a texture
mapping technique to achieve real-time pencil sketching. We
demonstrate our method of inking silhouettes, material and mesh
boundaries, and crease edges. In addition, we present techniques
for emphasizing motion of cartoon objects by introducing
geometry into the cartoon scene. The rendering system is
integrated with an animation system and a runtime multiresolution
mesh (MRM) system to achieve scalability, ensuring
real-time performance on any platform. Such solutions allow us
to take advantage of evolving hardware in order to make
nonphotorealistic animation and rendering achievable on low- and
high-end consumer platforms. All of the techniques described can
be applied to models created with standard modeling tools and
require no additional mark-up information from the modeler.
