abstract = {Light and shade in the context of non-photorealistic imaging, such
as digital cel animation, are semantic notations, rather than
physical phenomena. Therefore stylized light and shade should be
intentionally animated instead of simulated. This paper proposes
an intuitive, direct manipulation method for animating stylized
light and shade in real-time. Our method provides intuitive
click-and-drag operations for translating and deforming the shaded
areas, including rotation, directional scaling, splitting, and
squaring of high-lights, all without tedious parameter tuning. Our
prototype system demonstrates the algorithms in our method, which
are implemented along with a real-time cartoon shader on commodity
graphics hard-ware. This system allows the interactive creation of
stylized shading keyframes for animations, illustrating the
effectiveness of the proposed techniques.},
