Abstract:
We apply simple techniques from traditional artistic composition to
the art-based rendering of interactive 3D scenes. A human scenemodeler
makes choices about composition in a scene and our system
dynamically adjusts the rendering attributes of objects in the
scene to achieve the desired effects for a given view. We can selectively
group scene elements through shared tone, color, and outline,
so as to simplify and structure an image. This can be used, together
with controlled level of detail, to emphasize important objects. Finally,
we show a technique for adaptively changing color or other
attributes to control the contrast of adjacent elements in the picture.
We also briefly discuss ideas about larger-scale compositional
issues.
