Sketch and Paint-based Interface for Highlight Modeling
Proc. Eurographics Workshop on Sketch-based Interfaces and Modeling 2008, June 2008
In computer graphics, highlights capture much of the appearance of
light reflection off a surface. They are generally limited to
pre-defined models (e.g., Phong, Blinn) or to measured data.
In this paper, we introduce new tools and a corresponding highlight
model to provide computer graphics artists a more expressive approach
to design highlights. 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-and-view configurations, our system smoothly blends the
different user-defined highlights. Based on GPU cabilities, our solution
allows real-time editing and feedback. We illustrate our approach with
a wide range of highlights, with complex shapes and varying colors.
This solution also demonstrates the simplicity of introduced tools.
