Research Topics and Projects

This is a list of some of the projects I have worked on in the last couple of years.

	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.
	Responsive Interaction on Large Displays With the growing resolution on today's interactive displays it becomes increasingly difficult to maintain responsiveness of the system. I work on applying techniques from computer graphics to address the complexity issues on such interfaces.
	High Quality Rendering While doing research on line rendering and pen-and-ink NPR I found that, in particular if print is the medium aimed for, one should try to produce high quality images. This lead me to attempt to produce vector images of my NPR techniques wherever possible.
	Non-Photorealistic Illustration and Visualization Non-photorealistic rendering is inspired by a long tradition of illustration. I applied NPR techniques to illustration and visualization problems in medical, technical, and other domains. I also worked on combining NPR methods with other rendering techniques to create hybrid rendering styles for illustration and visualization.
	Silhouette and Pen-and-Ink Rendering Hand-drawn pen-and-ink drawings have fascinated me for a long time. Using non-photorealistic rendering I have worked on generating such drawings consisting of silhouette lines and other strokes with the computer.
