Three-dimensional maps are fundamental tools for presenting, exploring, and manipulating geo data. This paper describes multiresolution concepts for 3D maps and their texture-base...
A distance volume is a volume dataset where the value stored at each voxel is the shortest distance to the surface of the object being represented by the volume. Distance volumes ...
In this paper, we explore the perception of finger motions of virtual characters. In three experiments, designed to investigate finger animations, we asked the following questio...
