In this paper, we analyze the redundancy in calculating all pairs of geodesic distances on a rectangular grid. Fast marching method is an efficient way to estimate the geodesic di...
When teaching a course in compiler design, it is conventional to introduce the iterative calculation of least fixed points quite late in the course, in the guise of iterative dat...
In this paper, we outline two improvements to the fast sweeping method to improve the speed of the method in general and more specifically in cases where the speed is changing rapi...
Critical points of a vector field are key to their characterization. Not only their positions but also their indexes are crucial for understanding vector fields. Considerable wo...
To keep avatars and other moving objects on the ground in virtual environments, it is necessary to find the points where these objects should contact the terrain. This is often do...
