Overview

This example shows how to create an observer.

Expected Result

New Observer Result

Example details

To create an observer, you must first create an observer configuration.

   // First, create an observer configuration that describes the observer to 
   // create.  For this example, the default values are fine - we just need to 
   // supply a unique name.
   makVrv::DtObserverConfiguration observerConfig("Example Observer");

The configuration is then added to the DtInputDriver, which will realize the observer immediately if the application is running, or realize it on start up.

   // Then add the configuration to the input driver.  Since we added the 
   // configuration the input driver will create this observer each time it
   // is started.
   vantageApp.de().driverManager().inputDriver().addObserverConfiguration( 
      observerConfig );

Building the Example

VR-Vantage includes pre-built versions of the example application. To build it yourself, follow the instructions at Building VR-Vantage Examples, Applications, and Plug-ins.

Running the Example

This example is an application. You can run it by running ./bin64/exampleCreateObserver.exe (on Windows) or ./bin64/exampleCreateObserver (on Linux). Go in the "menu->Settings->Display Settings->Observer Settings", in the drop down menu "Observer", you should see a new entry "Example Observer".
