Integrating the IG into an existing application is very easy thanks to its comprehensive C++ SDK.
Accompagnied with an extensive documentation, the API is clear, simple and organized in an easy-to-understand way : set the camera position and view direction, add entities and move them, configure the date and time of day, add cloud layers, set the visibility distance, etc.
When using a multichannel configuration, there is no need to send any command to the slave positions, synchronization with the master will be automatically handled by the IG.
