  abstract = {This dissertation deals with the rendering of
              ``non-photorealistic'' illustrations (imitating drawings or
              paintings for instance) from 3D scenes. Abstraction or stylization
              enhance this type of rendering with communicative, aesthetic and
              expressive qualities that distinguish it from usual image
              synthesis. Our goals is to provide the user with a flexible
              control over the style of the non-photorealistic rendering and,
              also, to propose a style formulation that allows the reuse of the
              same style to render different 3D scenes. We chose a programmable
              approach that relies on the assumption that style attributes
              (color, thickness, ...) are chosen depending on generic
              information from the scene (line charasteristics, depth
              discontinuity, ...), and takes inspiration from procedural
              approaches (such as Pixar Renderman). The idea consists in
              expressing a style as a set of procedures specifying the relations
              between attributes and information: The user ``programs'' a style
              sheet that can be used to render several different 3D scenes or
              several images from an animated sequence. This approach is the
              first one to offer both flexible control over the style of the
              rendering and a reusable formulation of that style.},
