abstract = {To create a new, flexible system for volume illustration, we have
explored the use of Wang Cubes, the 3D extension of 2D Wang Tiles.
We use small sets of Wang Cubes to generate a large variety of
non-periodic illustrative 3D patterns and textures, and we develop
a direct volume rendering framework with these cubes. With the
generated patterns and textures, our framework can be used to
render volume datasets effectively and a variety of rendering
styles can be achieved with less storage. Specifically, we extend
the non-periodic tiling process of Wang Tiles to Wang Cubes and
modify it for multi-purpose tiling. We automatically generate
isotropic Wang Cubes consisting of 3D patterns or textures to
simulate various illustrative effects. Anisotropic Wang Cubes are
generated to yield patterns which reflect object properties by
using the volume data, curvature, and gradient information. We
also extent the definition of Wang Cubes into a set of different
sized cubes to provide multi-resolution volume rendering. Finally,
we provide both coherent 3D geometry-based and texture-based
rendering frameworks that can be integrated with arbitrary feature
exploration methods.},
