This is necessary if you would like to write a application which automatically connects a device using e.g. a IOSensor (See ). It only shows how to start a IO-Node and how to find the coresponding input/output slots. You still need to connect the streams to the application (e.g. using a IOSensor) and some code to process the input data (e.g. SteeringNavigator); The tutorial uses a simple joystick but the steps are in general the same for every device http://instantreality.org/tutorial/connecting-devices/http://instantreality.org/tutorial/get-your-engine-right/This tutorial shows you how to build up different elements of a more complex application by providing a scene, engine and context-setup description. The different parts allow the author to cluster and specify various aspects of your final application. The Scene contains the dynamic spatial content, the Engine contains device and environment specific parts (e.g. window or cluster setup) and the ContextSetup defines the application independent parts like the path of your java installation. The ContextSetup parameter are normally stored in the system preferences (e.g. plist-files on Mac or registry entries on Windows) but this tutorials shows how to overwrite the settings per applicationhttp://instantreality.org/tutorial/get-your-engine-right/http://instantreality.org/tutorial/hello-world-in-x3d/This tutorial shows you how to create a "Hello world!" in X3Dhttp://instantreality.org/tutorial/hello-world-in-x3d/
