VisibilityPolygon | Java implementation with GUI of paper A Linear Algorithm

VisibilityPolygon is a Java library. VisibilityPolygon has no bugs, it has no vulnerabilities and it has low support. However VisibilityPolygon build file is not available. You can download it from GitHub.

Visibility Polygon from a Given Point. --Java Implementation of the paper: A Linear Algorithm for Computing the Visibility Polygon from a Point by H. EL GINDY AND D. AVIS. License: Copyright 2012 Christine Xu. Open --- Open an existed ".vp" file, whose first line is the number of points n, and the next n lines are the x y coordinates for each point. Also, you can specify the n+1th line to be the x y coordinate of the visibility point inside the polygon. See attached sample test files. Save --- Save the current polygon and the visibility point into a ".vp" file, whose format is the same as indicated above. Exit --- Exit the entire program. Clear --- Clear the current graph, including all the vertices of the polygon and the visibility point. Select --- Instead of inserting points into polygon or modify the position of the given point, you can do nothing when you click the canvas. Visibility from a given point --- Do the visibility computation based on the shape of the current polygon and position of the given point, then show the result.
