Visual Comparison of Dijkstra and A-Star


I finalized the beta-version of my routing and OpenStreetMap (OSM) visualization tool.
The first idea was to see how the Dijkstra and A-Star algorithms work. The next idea was to use OSM data to render the roadnetwork and buildings.

The following videos and pictures show the different working style of Dijkstra and A-Star.
