SpeedTree is for procedurally generating large forests in realtime. they have wind data, normal mapping and diffuse mapping with alpha channels. They have a very large library of like 2000 plants and trees. So if you intend to create a large forest or jungle then it would it would be useful. My game that I am working on needs some lush areas but I do not have the 10,000 USD to plop down on a license. So therefore I will use either loopix or trees we create ourselves. Its a cool package but I dont think its worth 10k. GS out.
