Automatic Pen-and-Ink Illustration of Tone, Gloss, And Texture

We present a method for automatically depicting material appearance using pen and ink. Starting from a classical computer graphics representation -- color map, normal map, illumination, etc. -- we introduce an abstraction layer to bridge between this unsuited input and generic control parameters of pen-and-ink systems, such as primitive shape, size and density. This layer is made of parameters, belonging to tone, gloss and texture categories, that are automatically extracted from the input data. We then demonstrate our approach by presenting how this abstraction layer can easily be used to drive an example pen-and-ink rendering system. We show results on various materials, and validate our choices in a user study.
