Unigine::Plugins::SpiderVision::SpiderVisionConfig Class
| Header: | #include <plugins/Unigine/SpiderVision/UnigineSpiderVision.h> |
The object of this class describes the current configuration, stores information about all viewports and groups of the current configuration and provides an interface to interact with them.
DisplaysConfig Class
