Abstract: An object space algorithm for computing shadows in dynamic scenes illuminated by area light sources is presented. A mesh with the shadow boundaries as well as other disco...
This paper presents a technique for visualizing large spatial data sets in Web Mapping Systems (WMS). The technique creates a hierarchical clustering tree, which is subsequently u...
We propose a method to find candidate 2D articulated model configurations by searching for locally optimal configurations under a weak but computationally manageable fitness functi...
