Abstract:

I will focus on visual style representations for illustrative visualization. As different rendering styles are an effective means for accentuating features and directing the viewer s attention, an interactive illustrative visualization system needs to provide an easy-to-use yet powerful interface for changing these styles. The lecture will review existing approaches for stylized rendering and discuss practical considerations in the choice of an appropriate representation for visual styles.

I will also review the state-of-the-art of sketch-based interfaces and modeling (SBIM) for scientific visualization, including different aspects and inspiration factors brought from traditional medical/scientific illustration principles, methods and practices I will describe unique techniques and problems, including presentation of systems, algorithms and implementation techniques focusing on interactive SBIM for illustrative botanical modeling and volume graphics.
