GeodesicViewer – A tool for exploring geodesics in the theory of relativity
چکیده انگلیسی

The GeodesicViewer realizes exocentric two- and three-dimensional illustrations of lightlike and timelike geodesics in the general theory of relativity. By means of an intuitive graphical user interface, all parameters of a spacetime as well as the initial conditions of the geodesics can be modified interactively. This makes the GeodesicViewer a useful instrument for the exploration of geodesics in four-dimensional Lorentzian spacetimes.Program summaryProgram title: GeodesicViewerCatalogue identifier: AEFP_v1_0Program summary URL:http://cpc.cs.qub.ac.uk/summaries/AEFP_v1_0.htmlProgram obtainable from: CPC Program Library, Queen's University, Belfast, N.
