Hi, in standard Manipulator class has some functions as following virtual performMovementLeftMouseButton( const double eventTimeDelta, const double dx, const double dy ); virtual bool performMovementMiddleMouseButton( const double eventTimeDelta, const double dx, const double dy ); virtual bool performMovementRightMouseButton( const double eventTimeDelta, const double dx, const double dy ); virtual bool performMouseDeltaMovement( const float dx, const float dy ); what is eventTimeDelta,dx and dy ? and How i can get current mouse position in world position ? is there any predefined function or we have to write our own ? Thank you!
