VR-Link Examples

VR-Link is distributed with a number of examples.

These examples can be useful as test federates, or just starting points in for VR-Link development.

Simple examples showing how to connect to an exercise:

• Listen - A simple example that listens to an exercise. Listen prints out information about the first Entity it discovers.
• Talk - A simple example that publishes an object in an exercise. Talk publishes a stripped down F18 that flies in a straight line.

More complex examples:

• F18 - A complex F18 example that shows interactions and emitter systems in a full federate.
• Embark - A simple example which embarks a helicopter on an aircraft carrier.

Other Specific Functionality Examples:

• ListenC - Listen for the C language. Shows how to use VR-Link with C++ wrappers.
• Articulated Parts - A simple function which manipulates Articulated Parts.
• Performance Measuring - A simple function which uses a high resolution timer to measure performance for some code.
• Link 16 Helper Classes - Functions that demonstrate how to use the Link 16 helper classes for Radio Transmitter and Signal classes.
• Replacing the dead-reckoner/smoother - Functions that demonstrate how to replace the dead-reckoner or smoother for reflected entities.
• Threading - A simple program to show VR-Link threading classes.
• Multithreading publishers - an example that creates multiple F18 entities and demonstrates how to parallelize the simulation.
• Data Interactions - a simple example that demonstrates how to use data interactions to encode and decode any arbitrary information.

Object Publisher Examples:

• Environmental Process - An example for the Environmental Process Object.

HLA Examples

Simple examples using Special HLA features:

• DDM Talk - A modified version of the talk example that uses DDM.
• DDM Listen - A modified version of the listen example that uses DDM.
• Regulator (Time Managed Talk) - A modified version of the talk example that uses TM.
• Constrained (Time Managed Listen) - A modified version of the listen example that uses TM.
• MC02 Talk - A modified version of the talk example that uses MC02 standard DDM.
• MC02 Listen - A modified version of the listen example that uses MC02 standard DDM.
• Ownership Handler - an example that demonstrates ownership management in HLA

HLA Extension Examples:

• Add Attribute - Adds an attribute to Entities and Fire Interactions.
• Test Interaction - Adds a new interaction to a FOM.
• Test Object - Adds a new object to a FOM.

• Simple Test Interaction - Adds a new interaction to a FOM with the encoding/decoding embedded within the interaction.

  HLA FOM Mapping Examples

  • FOM Mapper - A FOM Mapper for a very simple FOM.
  • TAG Modification Example - How to encode/decode the User Tag in a FOM Mapper.

  For debugging:

  • HLA Netdump - Prints out HLA interactions and object updates.
