abstract = {This paper presents a novel system framework for interactive,
three-dimensional, stylized, abstract painterly rendering. In this
framework, the input models are first represented using 3D point
sets and then this point-based representation is used to build a
multiresolution bounding sphere hierarchy. From the leaf to root
nodes, spheres of various sizes are rendered into multiple-size
strokes on the canvas. The proposed sphere hierarchy is developed
using multiscale region segmentation. This segmentation task
assembles spheres with similar attribute regularities into a
meaningful region hierarchy. These attributes include colors,
positions, and curvatures. This hierarchy is very useful in the
following respects: 1) it ensures the screen-space stroke density,
2) controls different input model abstractions, 3) maintains
region structures such as the edges/boundaries at different
scales, and 4) renders models interactively. By choosing suitable
abstractions, brush stroke, and lighting parameters, we can
interactively generate various painterly styles. We also propose a
novel scheme that reduces the popping effect in animation
sequences. Many different stylized images can be generated using
the proposed framework.},
