We present an approach to example-based stylization of 3D renderings that
better preserves the rich expressiveness of hand-created artwork. Unlike
previous techniques, which are mainly guided by colors and normals, our
approach is based on light propagation in the scene. This novel type of
guidance can distinguish among context-dependent illumination effects, for
which artists typically use different stylization techniques, and delivers a
look closer to realistic artwork. In addition, we demonstrate that the current
state of the art in guided texture synthesis produces artifacts that can
significantly decrease the fidelity of the synthesized imagery, and propose an
improved algorithm that alleviates them. Finally, we demonstrate our method's
effectiveness on a variety of scenes and styles, in applications like
interactive shading study or autocompletion.
