Welcome to Interactive Data Visualization's SpeedTree® SDK 7.0.1. This help system, along with the source code for the reference applications in the SDK, contains all of the information you need to use the SpeedTree SDK effectively.
If you experience problems with SpeedTree, please contact IDV's technical support department. We can be reached from 9am to 6pm, Monday through Friday (EST) by email: email@example.com. Whether you're evaluating or a fully-licensed client, you'll receive a quick response directly from an engineer that's involved in the day-to-day development of the SpeedTree product suite.
This documentation is useful only to developers who are doing a custom integration of SpeedTree into their own engine. If you're using Unreal Engine 4 or Unity 5, SpeedTree has already been integrated and this documentation is of little to no use for your project.
