'''Project Aim'''
[[BR]]
The aim of the project is as follows:

a. ''Porting the Voronoi classes from JTS to GEOS:'' Providing the functionality of constructing Voronoi diagrams to GEOS by porting it from JTS to GEOS.

b. ''Writing C++ test cases:'' This will include porting the Voronoi Test file from JTS to GEOS. Furthermore one or two test cases will be written from scratch.

c. ''Exposing the functions through C-API:'' It provides a wrapper for the C++ functions. All the reference functions are implemented in geos_ts_c.cpp. (These are the thread safe apis). These functions are also exposed via the non-thread apis that are implemented in geos_c.cpp file. Such wrapper will be provided for the functions/methods that will be ported for Voronoi Class.

d. ''Writing C test cases:'' Test cases to test the Voronoi class methods wrapper functions written in geos_ts_c.cpp and geos_c.cpp will be written to test all the methods exposed via the apis.

=== Week1 Report ===
'''1. Work Done :'''
[[BR]]
  * Have ported the methods that are in geos/triangualte/quadedge/QuadEdgeSubdivion.cpp. The methods are as such:
     * getVoronoiDiagram
     * getVoronoiCellPolygons
     * getVoronoiCellPolygon
     * getVertexUniqueEdges
  * TriangleCircumcentreVisitor was also ported.
  * More methods like geos::geom::Triangle::circumcentre, and geos::geom::closeRing that were required in the above functions were also ported.
 

'''2. Problem Faced :'''
[[BR]]
  * I am having some silly problems during compilation which i am working out with strk, it will be solved soon.  

'''3. Work to be done in the next week :'''
[[BR]]
  * Solve the errors that are coming as of now.
  * Port the classes left, and see the working of the methods ported.
  * Start with the port of VoronoiDiagramBuilder.
