Hi,
I have the data for roads, their location(magnetic and geodetical), height and properties like whether it's one way or only for heavy vehicles and such. Now, how do I use this data to create a real time road network? Has someone done it earlier? Is it too ambitious for a Blitz3D application?
Need help.
