Abstract: We present techniques for rendering Hermite Radial Basis Function (HRBF) Implicits in different pen-and-ink styles. HRBF Implicits is a simple and compact representation, providing three fundamental qualities: a small number of point-normal samples as input for surface reconstruction, good projection of points near the surface, and smoothness of the gradient field. Our approach uses these qualities of HRBF implicits to generate a robust distribution of points to position the drawing primitives. The resulting implicit model is then rendered using point-based primitives to depict shape and tone using silhouettes with hidden-line attenuation, drawing directions, and stippling. We present sample renderings obtained for a variety of models.
