I would like to share some progress on my open source project: UtyMap. This is a library which provides highly customizable API for procedural world generation based on real map data, e.g. OpenStreetMap, NaturalEarth. Core logic is written on C++11 and can be used on many platforms as it has no dependency to specific game engine or application framework. Demo application is built using Unity3D and it provides examples with interactive world creation at different zoom levels, including globe and ground: Full source code is available here: https://github.com/reinterpretcat/utymap Latest release binaries: https://github.com/reinterpretcat/utymap/releases/tag/ver1.1 Released on Google Play: https://play.google.com/store/apps/details?id=com.utymap.demo Update from July 2016: Initial post referred to ActionStreetMap project which is now deprecated and not supported, but full source code is available.
