Résumé en anglais

In computer graphics, highlights capture much of the appearance of light reflection off a surface. They are generallylimited to pre-defined models (e.g., Phong, Blinn) or to measured data. In this paper, we introduce new toolsand a corresponding highlight model to provide computer graphics artists a more expressive approach to designhighlights. For each defined light key-direction, the artist simply sketches and paints the main highlight features(shape, intensity, and color) on a plane oriented perpendicularly to the reflected direction. For other light-andviewconfigurations, our system smoothly blends the different user-defined highlights. Based on GPU abilities, oursolution allows real-time editing and feedback. We illustrate our approach with a wide range of highlights, withcomplex shapes and varying colors. This solution also demonstrates the simplicity of introduced tools< Réduire
