OpenStreetMap to Valve Map Format converter

This is a console program that imports *.osm XML text file, and exports vmf, obj and map . Currently, it uses information only about buildings.

Since only convex polygons can be used in vmf/map, the program uses the polygon decomposition algorithm created by Mark Bayazit.

How to use it

1. Export osm data from https://www.openstreetmap.org

2. Execute osm2vmf.exe with path to file as argument

   Optional arguments:

   -obj

   -map

   -novmf

3. Open created vmf file in VHE 4.x or Hammer++ (map file in VHE 3.x, JACK or TrenchBroom)

4. Add some entities

5. Compile and run map
