Updating Algorithms for Constraint Delaunay TIN
Updating Algorithm Constraint Delaunay TIN Integral Ear Elimination Influence Domain Re-Triangulation Polymorphism
font style='font-size:12px;'>
2015/10/12
Present algorithms for D-TIN are far insufficient for the dynamic updating of CD-TIN in different applications. This paper,
based on improvement to present insertion and deletion algorithms for D-TI...
Dynamic Cartography Using Voronoi/Delaunay Methods
Voronoi Delaunay kinetic data structures dynamic topology interactive cartography
font style='font-size:12px;'>
2015/10/9
We describe two reversible line-drawing methods for cartographic applications based on the kinetic (moving-point)
Voronoi diagram. Our objectives were to optimize the user’s ability to draw and edit...
ENCODING AND DECODING OF PLANAR MAPS THROUGH CONFORMING DELAUNAY TRIANGULATIONS
