Interacting with Non-Photorealistic Rendering

Many NPR techniques are encapsulated algorithms that allow little influence on the final product other than global parameter changes. In addition, interfaces for NPR are often cluttered with an enormous number of parameters whose influence is difficult to understand. I work on giving people understandable and direct local control over the rendering process.
