SuperSplines Pro enables you to define, edit and use complex curves in your games.
Edit your splines in realtime in the Editor or let them be created dynamically. SuperSplines combines easy handling with powerful functionality. It also allows you to dynamically generate roads, rivers, tubes and other curved meshes in the Editor!
Note that this is the pro version of SuperSplines. It's sold at a higher price than the regular version but it comes with the complete source code!
