要旨:
We propose an approach to �pack� a set of two-dimensional graphical primitives
into a spatial layout that follows artistic goals. We formalize this process as
projecting from a high-dimensional feature space into a 2D layout. Our system
does not expose the control of this projection to the user in form of sliders
or similar interfaces. Instead, we infer the desired layout of all primitives
from interactive placement of a small subset of example primitives. To produce
a pleasant distribution of primitives with spatial extend, we produce a
pleasant distribution of primitives with spatial extend, we propose a novel
generalization of Centroidal Voronoi Tesselation which equalizes the distances
between boundaries of nearby primitives. Compared to previous primitive
distribution approaches our GPU implementation achieves both better fidelity
and asymptotically higher speed. A user study evaluates the system�s usability.
